创建数据库vueblog然后执行下面命令生成表
DROP TABLE IF EXISTS `m_blog`; /*!40101 SET @saved_cs_client = @@character_set_client */; SET character_set_client = utf8mb4 ; CREATE TABLE `m_blog` ( `id` bigint(20) NOT NULL AUTO_INCREMENT, `user_id` bigint(20) NOT NULL, `title` varchar(255) NOT NULL, `description` varchar(255) NOT NULL, `content` longtext, `created` datetime NOT NULL ON UPDATE CURRENT_TIMESTAMP, `status` tinyint(4) DEFAULT NULL, PRIMARY KEY (`id`) ) ENGINE=InnoDB AUTO_INCREMENT=21 DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_0900_ai_ci; /*!40101 SET character_set_client = @saved_cs_client */; DROP TABLE IF EXISTS `m_user`; /*!40101 SET @saved_cs_client = @@character_set_client */; SET character_set_client = utf8mb4 ; CREATE TABLE `m_user` ( `id` bigint(20) NOT NULL AUTO_INCREMENT, `username` varchar(64) DEFAULT NULL, `avatar` varchar(255) DEFAULT NULL, `email` varchar(64) DEFAULT NULL, `password` varchar(64) DEFAULT NULL, `status` int(5) NOT NULL, `created` datetime DEFAULT NULL, `last_login` datetime DEFAULT NULL, PRIMARY KEY (`id`), KEY `UK_USERNAME` (`username`) USING BTREE ) ENGINE=InnoDB AUTO_INCREMENT=2 DEFAULT CHARSET=utf8; /*!40101 SET character_set_client = @saved_cs_client */; INSERT INTO `vueblog`.`m_user` (`id`, `username`, `avatar`, `email`, `password`, `status`, `created`, `last_login`) VALUES ('1', 'markerhub', 'https://image-1300566513.cos.ap-guangzhou.myqcloud.com/upload/images/5a9f48118166308daba8b6da7e466aab.jpg', NULL, '96e79218965eb72c92a549dd5a330112', '0', '2020-04-20 10:44:01', NULL);
1.0 配置分页
创建MybatisPlusConfig类(创建路径com/vueblog/config)
package com.vueblog.config; import com.baomidou.mybatisplus.extension.plugins.PaginationInterceptor; import org.mybatis.spring.annotation.MapperScan; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import org.springframework.transaction.annotation.EnableTransactionManagement; @Configuration @EnableTransactionManagement @MapperScan("com.markerhub.mapper") public class MybatisPlusConfig { @Bean public PaginationInterceptor paginationInterceptor() { PaginationInterceptor paginationInterceptor = new PaginationInterceptor(); return paginationInterceptor; } }
2.0 生成代码
创建CodeGenerator(在com.vueblog包下面)
**修改对应的数据库:账号密码、数据库名、包配置(ctrl+f可找到对应位置) **
然后运行输入俩表 ,号隔开是多表
package com.vueblog; import com.baomidou.mybatisplus.core.exceptions.MybatisPlusException; import com.baomidou.mybatisplus.core.toolkit.StringPool; import com.baomidou.mybatisplus.core.toolkit.StringUtils; import com.baomidou.mybatisplus.generator.AutoGenerator; import com.baomidou.mybatisplus.generator.InjectionConfig; import com.baomidou.mybatisplus.generator.config.*; import com.baomidou.mybatisplus.generator.config.po.TableInfo; import com.baomidou.mybatisplus.generator.config.rules.NamingStrategy; import com.baomidou.mybatisplus.generator.engine.FreemarkerTemplateEngine; import java.util.ArrayList; import java.util.List; import java.util.Scanner; // 演示例子,执行 main 方法控制台输入模块表名回车自动生成对应项目目录中 public class CodeGenerator { /** * <p> * 读取控制台内容 * </p> */ public static String scanner(String tip) { Scanner scanner = new Scanner(System.in); StringBuilder help = new StringBuilder(); help.append("请输入" + tip + ":"); System.out.println(help.toString()); if (scanner.hasNext()) { String ipt = scanner.next(); if (StringUtils.isNotEmpty(ipt)) { return ipt; } } throw new MybatisPlusException("请输入正确的" + tip + "!"); } public static void main(String[] args) { // 代码生成器 AutoGenerator mpg = new AutoGenerator(); // 全局配置 GlobalConfig gc = new GlobalConfig(); String projectPath = System.getProperty("user.dir"); gc.setOutputDir(projectPath + "/src/main/java"); // gc.setOutputDir("D:\test"); gc.setAuthor("anonymous"); gc.setOpen(false); // gc.setSwagger2(true); 实体属性 Swagger2 注解 gc.setServiceName("%sService"); mpg.setGlobalConfig(gc); // 数据源配置 数据库名 账号密码 DataSourceConfig dsc = new DataSourceConfig(); dsc.setUrl("jdbc:mysql://localhost:3306/vueblog?useUnicode=true&useSSL=false&characterEncoding=utf8&serverTimezone=UTC"); // dsc.setSchemaName("public"); dsc.setDriverName("com.mysql.cj.jdbc.Driver"); dsc.setUsername("root"); dsc.setPassword("123456"); mpg.setDataSource(dsc); // 包配置 PackageConfig pc = new PackageConfig(); pc.setModuleName(null); pc.setParent("com.vueblog"); mpg.setPackageInfo(pc); // 自定义配置 InjectionConfig cfg = new InjectionConfig() { @Override public void initMap() { // to do nothing } }; // 如果模板引擎是 freemarker String templatePath = "/templates/mapper.xml.ftl"; // 如果模板引擎是 velocity // String templatePath = "/templates/mapper.xml.vm"; // 自定义输出配置 List<FileOutConfig> focList = new ArrayList<>(); // 自定义配置会被优先输出 focList.add(new FileOutConfig(templatePath) { @Override public String outputFile(TableInfo tableInfo) { // 自定义输出文件名 , 如果你 Entity 设置了前后缀、此处注意 xml 的名称会跟着发生变化! return projectPath + "/src/main/resources/mapper/" + "/" + tableInfo.getEntityName() + "Mapper" + StringPool.DOT_XML; } }); cfg.setFileOutConfigList(focList); mpg.setCfg(cfg); // 配置模板 TemplateConfig templateConfig = new TemplateConfig(); templateConfig.setXml(null); mpg.setTemplate(templateConfig); // 策略配置 StrategyConfig strategy = new StrategyConfig(); strategy.setNaming(NamingStrategy.underline_to_camel); strategy.setColumnNaming(NamingStrategy.underline_to_camel); strategy.setEntityLombokModel(true); strategy.setRestControllerStyle(true); strategy.setInclude(scanner("表名,多个英文逗号分割").split(",")); strategy.setControllerMappingHyphenStyle(true); strategy.setTablePrefix("m_"); mpg.setStrategy(strategy); mpg.setTemplateEngine(new FreemarkerTemplateEngine()); mpg.execute(); } }
效果如下:
1.0 UserController类(ctrl+R可全局搜索类)
package com.vueblog.controller; import com.vueblog.service.UserService; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.web.bind.annotation.GetMapping; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RestController; /** * <p> * 前端控制器 * </p> * * @author * @since 2021-02-05 */ @RestController @RequestMapping("/user") public class UserController { @Autowired private UserService userService; @GetMapping("/index") public Object index(){ return userService.getById(1); } }
2.0 运行项目 查看效果
这里我们用到了一个Result的类,这个用于我们的异步统一返回的结果封装。一般来说,结果里面有几个要素必要的
Result类(路径com.vueblog.common.lang;)
package com.vueblog.common.lang;
import lombok.Data;
import java.io.Serializable;
@Data
public class Result implements Serializable { //序列化
private int code; //200是正常 400表示异常
private String msg;
private Object data;//返回数据
//成功
public static Result succ( Object data){
return succ(200,"操作成功",data); } //成功 public static Result succ(int code,String msg,Object data){ Result r = new Result(); r.setCode(code); r.setMsg(msg); r.setData(data); return r; } //失败 public static Result fail(String msg){ return fail(400,msg,null); } //失败 public static Result fail(String msg,Object data){ return fail(400,msg,data); } //失败 public static Result fail(int code,String msg,Object data){ Result r = new Result(); r.setCode(code); r.setMsg(msg); r.setData(data); return r; }
}
在UserController 中引用测试
package com.vueblog.controller;
import com.vueblog.common.lang.Result;
import com.vueblog.entity.User;
import com.vueblog.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
/**
前端控制器
@author
@since 2021-02-05
*/
@RestController
@RequestMapping("/user")
public class UserController {
@Autowired
private UserService userService;
@GetMapping("/index")
public Object index(){
User user = userService.getById(1);
return Result.succ(200,“操作成功”,user);
}
}
页面运行效果图 (http://localhost:8081/user/index)
考虑到后面可能需要做集群、负载均衡等,所以就需要会话共享,而shiro的缓存和会话信息,我们一般考虑使用redis来存储这些数据,所以,我们不仅仅需要整合shiro,同时也需要整合redis。在开源的项目中,我们找到了一个starter可以快速整合shiro-redis,配置简单,这里也推荐大家使用。
而因为我们需要做的是前后端分离项目的骨架,所以一般我们会采用token或者jwt作为跨域身份验证解决方案。所以整合shiro的过程中,我们需要引入jwt的身份验证过程。
那么我们就开始整合:
我们使用一个shiro-redis-spring-boot-starter的jar包,具体教程可以看官方文档:github.com/alexxiyang/…
导入shiro-redis的starter包:还有jwt的工具包,以及为了简化开发,引入hutool工具包。
pom.xml中导入:
<!-- shiro-redis --> <dependency> <groupId>org.crazycake</groupId> <artifactId>shiro-redis-spring-boot-starter</artifactId> <version>3.2.1</version> </dependency> <!-- hutool工具类 --> <dependency> <groupId>cn.hutool</groupId> <artifactId>hutool-all</artifactId> <version>5.3.3</version> </dependency> <!-- jwt 生成工具 校验工具--> <dependency> <groupId>io.jsonwebtoken</groupId> <artifactId>jjwt</artifactId> <version>0.9.1</version> </dependency>

路径:resources/WETA-INF/
restart.include.shiro-redis=/shiro-[\w-\.]+jar
小提示:登录调用AccountRealm类下面的doGetAuthenticationInfo
创建类AccountProfile 用于传递数据
路径:com.vueblog.shiro
package com.vueblog.shiro; import lombok.Data; import java.io.Serializable; @Data public class AccountProfile implements Serializable { private Long id; private String username; private String avatar; private String email; }
完善AccountRealm
package com.vueblog.shiro; import cn.hutool.core.bean.BeanUtil; import com.vueblog.entity.User; import com.vueblog.service.UserService; import com.vueblog.util.JwtUtils; import org.apache.shiro.authc.*; import org.apache.shiro.authz.AuthorizationInfo; import org.apache.shiro.realm.AuthorizingRealm; import org.apache.shiro.subject.PrincipalCollection; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Component; @Component public class AccountRealm extends AuthorizingRealm { @Autowired JwtUtils jwtUtils; @Autowired UserService userService; //为了让realm支持jwt的凭证校验 @Override public boolean supports(AuthenticationToken token) { return token instanceof JwtToken; } //权限校验 @Override protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) { return null; } //登录认证校验 @Override protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException { JwtToken jwtToken = (JwtToken) token; //获取userId String userId = jwtUtils.getClaimByToken((String) jwtToken.getPrincipal()).getSubject(); //获取用户内容 User user = userService.getById(Long.valueOf(userId)); if(user == null){ throw new UnknownAccountException("账户不存在"); } if(user.getStatus() == -1){ throw new LockedAccountException("账户不存在"); } AccountProfile profile = new AccountProfile(); BeanUtil.copyProperties(user,profile);//将user数据转移到profile //用户信息 密钥token 用户名字 return new SimpleAuthenticationInfo(profile,jwtToken.getCredentials(),getName()); } }
创建GlobalExceptionHandler 类
捕获全局异常
package com.vueblog.common.exception; import com.vueblog.common.lang.Result; import lombok.extern.slf4j.Slf4j; import org.apache.shiro.ShiroException; import org.springframework.http.HttpStatus; import org.springframework.web.bind.annotation.ExceptionHandler; import org.springframework.web.bind.annotation.ResponseStatus; import org.springframework.web.bind.annotation.RestControllerAdvice; /** * 日志输出 * 全局捕获异常 */ @Slf4j @RestControllerAdvice public class GlobalExceptionHandler { @ResponseStatus(HttpStatus.UNAUTHORIZED) //因为前后端分离 返回一个状态 一般是401 没有权限 @ExceptionHandler(value = ShiroException.class)//捕获运行时异常ShiroException是大部分异常的父类 public Result handler(ShiroException e){ log.error("运行时异常:-----------------{}",e); return Result.fail(401,e.getMessage(),null); } @ResponseStatus(HttpStatus.BAD_REQUEST) //因为前后端分离 返回一个状态 @ExceptionHandler(value = RuntimeException.class)//捕获运行时异常 public Result handler(RuntimeException e){ log.error("运行时异常:-----------------{}",e); return Result.fail(e.getMessage()); } }
然而我们运行测试发现并没有拦截
因为我们没有进行登录拦截
@RequiresAuthentication//登录拦截注解
运行效果:
提示401登录异常
当我们表单数据提交的时候,前端的校验我们可以使用一些类似于jQuery Validate等js插件实现,而后端我们可以使用Hibernate validatior来做校验。
我们使用springboot框架作为基础,那么就已经自动集成了Hibernate validatior。(校验登录非空等等)
User实体类中
import javax.validation.constraints.Email;
import javax.validation.constraints.NotBlank;
…
@TableName(“m_user”)
public class User implements Serializable {
private static final long serialVersionUID = 1L;
@TableId(value = “id”, type = IdType.AUTO)
private Long id;
@NotBlank(message = “昵称不能为空”)
private String username;
@NotBlank(message = “邮箱不能为空”)
@Email(message = “邮箱格式不正确”)
private String email;
...
}
在userController类中写一个方法测试
/** * *@RequestBody主要用来接收前端传递给后端的json字符串中的数据的(请求体中的数据的); * GET方式无请求体,所以使用@RequestBody接收数据时, * 前端不能使用GET方式提交数据, * 而是用POST方式进行提交。在后端的同一个接收方法里, * @RequestBody与@RequestParam()可以同时使用,@RequestBody最多只能有一个, * 而@RequestParam()可以有多个。 * * @Validated注解用于检查user中填写的规则 如果不满足抛出异常 * 可在GlobalExceptionHandler中捕获此异常 进行自定义 返回数据信息 */ @PostMapping("/save") public Result save(@Validated @RequestBody User user){ return Result.succ(user); }
启动postMan测试
如果postman没法启动
可以新建一个环境变量POSTMAN_DISABLE_GPU = true。
1.打开高级系统设置;
2.在“高级”选项卡中,单击“环境变量”;
3.添加一个新的系统变量;
4.关闭Postman并重新打开
定义捕获异常返回处理
在捕获异常 GlobalExceptionHandler类中修改如下:
/** * 实体校验异常 * MethodArgumentNotValidException捕获实体校验异常 */ @ResponseStatus(HttpStatus.BAD_REQUEST) //因为前后端分离 返回一个状态 @ExceptionHandler(value = MethodArgumentNotValidException.class)//捕获运行时异常 public Result handler(MethodArgumentNotValidException e){ log.error("实体捕获异常 :-----------------{}",e); BindingResult bindingException = e.getBindingResult(); //多个异常顺序抛出异常 ObjectError objectError = bindingException.getAllErrors().stream().findFirst().get(); return Result.fail(objectError.getDefaultMessage()); }
效果如下:(变得简短了)
输入正确的格式如下:
返回了我们需要的信息
因为是前后端分析,所以跨域问题是避免不了的,我们直接在后台进行全局跨域处理:
路径:com.vueblog.config
注意:此配置是配置到confroller的,在confroller之前是经过jwtFilter,所以在进行访问之前配置一下Filter的跨域问题
package com.vueblog.config; import org.springframework.context.annotation.Configuration; import org.springframework.web.servlet.config.annotation.CorsRegistry; import org.springframework.web.servlet.config.annotation.WebMvcConfigurer; /** * 解决跨域问题 */ @Configuration public class CorsConfig implements WebMvcConfigurer { @Override public void addCorsMappings(CorsRegistry registry) { registry.addMapping("/**") .allowedOrigins("*") .allowedMethods("GET", "HEAD", "POST", "PUT", "DELETE", "OPTIONS") .allowCredentials(true) .maxAge(3600) .allowedHeaders("*"); } }
jwtFilter进行跨域处理:
路径:com.vueblog.shiro
/** * 对跨域提供支持 * @param request * @param response * @return * @throws Exception */ @Override protected boolean preHandle(ServletRequest request, ServletResponse response) throws Exception { HttpServletRequest httpServletRequest = WebUtils.toHttp(request); HttpServletResponse httpServletResponse = WebUtils.toHttp(response); httpServletResponse.setHeader("Access-control-Allow-Origin", httpServletRequest.getHeader("Origin")); httpServletResponse.setHeader("Access-Control-Allow-Methods", "GET,POST,OPTIONS,PUT,DELETE"); httpServletResponse.setHeader("Access-Control-Allow-Headers", httpServletRequest.getHeader("Access-Control-Request-Headers")); // 跨域时会首先发送一个OPTIONS请求,这里我们给OPTIONS请求直接返回正常状态 if (httpServletRequest.getMethod().equals(RequestMethod.OPTIONS.name())) { httpServletResponse.setStatus(org.springframework.http.HttpStatus.OK.value()); return false; } return super.preHandle(request, response); }
----基本框架已经搭建完成-----
创建LoginDto
路径: com.vueblog.common.dto
package com.vueblog.common.dto;
import lombok.Data;
import javax.validation.constraints.NotBlank;
import java.io.Serializable;
@Data
public class LoginDto implements Serializable {
@NotBlank(message = "用户名不能为空") private String username; @NotBlank(message = "密码不能为空") private String password;
}
在GlobalExceptionHandler类中增加断言异常
路径:com.vueblog.common.exception
/**
* 断言异常
* @param e
* @return
*/
@ResponseStatus(HttpStatus.BAD_REQUEST)
@ExceptionHandler(value = IllegalArgumentException.class)
public Result handler(IllegalArgumentException e){
log.error(“Assert异常:------------------>{}”,e);
return Result.fail(e.getMessage());
}
创建AccountController类
登录和退出逻辑
package com.vueblog.controller;
import cn.hutool.core.lang.Assert;
import cn.hutool.core.map.MapUtil;
import cn.hutool.crypto.SecureUtil;
import com.baomidou.mybatisplus.core.conditions.query.QueryWrapper;
import com.vueblog.common.dto.LoginDto;
import com.vueblog.common.lang.Result;
import com.vueblog.entity.User;
import com.vueblog.service.UserService;
import com.vueblog.util.JwtUtils;
import org.apache.shiro.SecurityUtils;
import org.apache.shiro.authz.annotation.RequiresAuthentication;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.validation.annotation.Validated;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import javax.servlet.http.HttpServletResponse;
@RestController
public class AccountController {
@Autowired UserService userService; @Autowired JwtUtils jwtUtils; @RequestMapping("/login") public Result login(@Validated @RequestBody LoginDto loginDto, HttpServletResponse response){ User user = userService.getOne(new QueryWrapper<User>().eq("username", loginDto.getUsername())); Assert.notNull(user,"用户不存在");//断言拦截 //判断账号密码是否错误 因为是md5加密所以这里md5判断 if(!user.getPassword().equals(SecureUtil.md5(loginDto.getPassword()))){ //密码不同则抛出异常 return Result.fail("密码不正确"); } String jwt = jwtUtils.generateToken(user.getId()); //将token 放在我们的header里面 response.setHeader("Authorization",jwt); response.setHeader("Access-control-Expose-Headers","Authorization"); return Result.succ(MapUtil.builder() .put("id",user.getId()) .put("username",user.getUsername()) .put("avatar",user.getAvatar()) .put("email",user.getEmail()).map() ); } //需要认证权限才能退出登录 @RequiresAuthentication @RequestMapping("/logout") public Result logout() { //退出登录 SecurityUtils.getSubject().logout(); return null; }
}
运行效果:
创建工具类ShiroUtil
路径om.vueblog.util,可于判断等等
package com.vueblog.util;
import com.vueblog.shiro.AccountProfile;
import org.apache.shiro.SecurityUtils;
public class ShiroUtil {
public static AccountProfile getProfile(){
return (AccountProfile) SecurityUtils.getSubject().getPrincipal(); }
}
完善BlogController类
package com.vueblog.controller;
import cn.hutool.core.bean.BeanUtil;
import cn.hutool.core.lang.Assert;
import com.baomidou.mybatisplus.core.conditions.query.QueryWrapper;
import com.baomidou.mybatisplus.core.metadata.IPage;
import com.baomidou.mybatisplus.extension.plugins.pagination.Page;
import com.vueblog.common.lang.Result;
import com.vueblog.entity.Blog;
import com.vueblog.service.BlogService;
import com.vueblog.util.ShiroUtil;
import org.apache.shiro.authz.annotation.RequiresAuthentication;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.validation.annotation.Validated;
import org.springframework.web.bind.annotation.*;
import java.time.LocalDateTime;
/**

*/
@RestController
public class BlogController {
@Autowired
BlogService blogService;
//木有值默认为1
@GetMapping("/blogs")
public Result list(@RequestParam(defaultValue = “1”) Integer currentPage){
Page page = new Page(currentPage, 5);
IPage pageData = blogService.page(page, new QueryWrapper().orderByDesc(“created”));
return Result.succ(pageData);
}
//@PathVariable动态路由
@GetMapping("/blog/{id}")
public Result detail(@PathVariable Long id){
Blog blog = blogService.getById(id);
//判断是否为空 为空则断言异常
Assert.notNull(blog,“该博客已被删除”);
return Result.succ(blog);
}
//@Validated校验
//@RequestBody
//添加删除 木有id则添加 有id则编辑
@RequiresAuthentication //需要认证之后才能操作
@PostMapping("/blog/edit")
public Result edit(@Validated @RequestBody Blog blog){
//一个空对象用于赋值 Blog temp = null; //如果有id则是编辑 if(blog.getId() != null){ temp = blogService.getById(blog.getId());//将数据库的内容传递给temp //只能编辑自己的文章 Assert.isTrue(temp.getUserId().longValue()== ShiroUtil.getProfile().getId().longValue(),"没有编辑权限"); } else { temp = new Blog(); temp.setUserId(ShiroUtil.getProfile().getId()); temp.setCreated(LocalDateTime.now()); temp.setStatus(0); } //将blog的值赋给temp 忽略 id userid created status 引用于hutool BeanUtil.copyProperties(blog,temp,"id","userId","created","status"); blogService.saveOrUpdate(temp); return Result.succ(null);
}
//@PathVariable动态路由
@RequiresAuthentication //需要认证之后才能操作
@PostMapping("/blogdel/{id}")
public Result del(@PathVariable Long id){
boolean b = blogService.removeById(id);
//判断是否为空 为空则断言异常
if(b==true){
return Result.succ("文章删除成功");
}else{
return Result.fail(“文章删除失败”);
}
}
}
运行程序

{ "title":"标题测试", "description":"描述测试哦奥德萨", "content":"内容测试阿斯顿撒哦i等哈送到哈桑" }
修改
{ "id":21, "title":"标题测试修改", "description":"描述测试哦奥德萨", "content":"内容测试阿斯顿撒哦i等哈送到哈桑" }
文章删除
后端的一个骨架基本完成然后开始我们的前端开发
接下来,我们来完成vueblog前端的部分功能。可能会使用的到技术如下:
vue
element-ui
axios
mavon-editor
markdown-it
github-markdown-css
https://nodejs.org/zh-cn/
安装完成之后检查下版本信息:
接下来,我们安装vue的环境
npm install -g cnpm --registry=https://registry.npm.taobao.org
cnpm install --g vue-cli
选中要建立的文件cmd打开
进入你的项目目录,创建一个基于 webpack 模板的新项目: vue init webpack 项目名
输入:
vue init webpack xx
全部enter即可
完成
运行项目
进入demo(项目)目录 运行
cd demo npm run dev
浏览器打开

集成开发工具Visual Studio Code(VsCode)
汉化插件:chinese
插件如何导入和一些推荐插件:
https://blog.csdn.net/jiandan1127/article/details/85957003/
ctrl+`(~键)打开终端
输入:
npm run dev
效果如下则成功:
https://element.eleme.cn/#/zh-CN/component/installation
ctrl+`(~键)打开终端输入安装命令
# 安装element-ui cnpm install element-ui --save
然后我们打开项目src目录下的main.js,引入element-ui依赖。
import Element from 'element-ui' import "element-ui/lib/theme-chalk/index.css" Vue.use(Element)
测试elementUi是否引入成功
import Vue from ‘vue’
import Router from ‘vue-router’
import HelloWorld from ‘@/components/HelloWorld’
import Demo from ‘@/views/Demo’
Vue.use(Router)
export default new Router({
routes: [
{
path: ‘/’,
name: ‘HelloWorld’,
component: HelloWorld
}, {
path: ‘/Demo’,
name: ‘Demo’,
component: Demo
}
]
})
新建Demo.vue
src/views/demo
引入button按钮(官方直接复制)
<template> <div class="Demo"> {{msg}} <el-button type="primary">主要按钮</el-button> </div> </template> <script> export default{ name: "Demo", data() { return { msg: "测试" }; } } </script>
App.vue添加:
Demo页面autoOpenBrowser修改为true。
autoOpenBrowser:true
接下来,我们来安装axios(www.axios-js.com/),axios是一个基于 promise 的 HTTP 库,这样我们进行前后端对接的时候,使用这个工具可以提高我们的开发效率。
安装命令:
cnpm install axios --save
然后同样我们在main.js中全局引入axios。
import axios from ‘axios’
//引用全局
Vue.prototype.$axios = axios
接下来,我们先定义好路由和页面,因为我们只是做一个简单的博客项目,页面比较少,所以我们可以直接先定义好,然后在慢慢开发,这样需要用到链接的地方我们就可以直接可以使用:
我们在views文件夹下定义几个页面:
BlogDetail.vue(博客详情页)
BlogEdit.vue(编辑博客)
Blogs.vue(博客列表)
Login.vue(登录页面)
可以配置插件:VueHelper(新建vue项目 最上方输入vuet按键tab可直接生成模板)
建立页面完成
注意:每个页面下方<template><temlate> 里面只能有一个<div></div>
路径:rountr/index.js
import Vue from 'vue' import Router from 'vue-router' import HelloWorld from '@/components/HelloWorld' import Demo from '@/views/Demo' import Login from '@/views/Login' import Blogs from '@/views/Blogs' import BlogEdit from '@/views/BlogEdit' import BlogDetail from '@/views/BlogDetail' Vue.use(Router) export default new Router({ routes: [ { path: '/', name: 'Index', redirect:{name : "Blogs"} }, { path: '/blogs', name: 'Blogs', component: Blogs },{ path: '/Login', name: 'Login', component: Login },{ path: '/blog/add', name: 'BlogEdit', component: BlogEdit }, { path: '/Demo', name: 'Demo', component: Demo },{ path: '/blog/:blogid', name: 'BlogDetail', component: BlogDetail } ,{ path: '/blog/:blogid/edit', name: 'BlogEdit', component: BlogEdit } ]})
打开终端 npm run dev启动项目
可自行测试其他路由
测试完我们可以删掉App.vue中的测试和图片
Login.vie
<template> <div> <el-container> <el-header> <img class="mlogo" src="../assets/logo.jpg" alt="logo图片" /> </el-header> <el-main> <el-form :model="ruleForm" :rules="rules" ref="ruleForm" label-width="100px" class="demo-ruleForm"> <el-form-item label="用户姓名" prop="username"> <el-input v-model="ruleForm.username"></el-input> </el-form-item> <el-form-item label="用户密码" prop="password"> <el-input v-model="ruleForm.password"></el-input> </el-form-item> <el-form-item> <el-button type="primary" @click="submitForm('ruleForm')">立即创建</el-button> <el-button @click="resetForm('ruleForm')">重置</el-button> </el-form-item> </el-form> </el-main> </el-container> </div> </template> <script> export default { name: "Login", data () { return { ruleForm: { username: '', password: '' }, rules: { username: [ { required: true, message: '请输入用户名称', trigger: 'blur' }, { min: 3, max: 15, message: '长度在 3 到 15 个字符', trigger: 'blur' } ], password: [ { required: true, message: '请选择密码', trigger: 'blur' } ] } }; }, methods: { submitForm (formName) { this.$refs[formName].validate((valid) => { if (valid) { alert('submit!'); } else { console.log('error submit!!'); return false; } }); }, resetForm (formName) { this.$refs[formName].resetFields(); } } } </script> <style scoped> .el-header, .el-footer { background-color: #b3c0d1; color: #333; text-align: center; line-height: 60px; } .el-main { /* background-color: #e9eef3; */ color: #333; text-align: center; line-height: 160px; } .mlogo { height: 80%; } .demo-ruleForm { max-width: 500px; margin: 0 auto; } </style>
在src包下面创建stroe文件夹
然后创建index.js
import Vue from 'vue' import Vuex from 'vuex'; Vue.use(Vuex) export default new Vuex.Store({ state: { token:'', userInfo:{} }, mutations: { }, actions: { }, modules: { } })
然后我们给main.js中引入store
// 存储 import store from './store' //在new Vue({}) 里面加入store new Vue({ el: '#app', router, store , components: { App }, template: '<App/>' }) // The Vue build version to load with the `import` command // (runtime-only or standalone) has been set in webpack.base.conf with an alias. import Vue from 'vue' import App from './App' // 存储 import store from './store' // 路由 import router from './router' // 引入element-ui依赖 import Element from 'element-ui' import "element-ui/lib/theme-chalk/index.css" // 引入axios依赖 import axios from 'axios' //引用全局 Vue.prototype.$axios = axios Vue.use(Element) Vue.config.productionTip = false /* eslint-disable no-new */ new Vue({ el: '#app', router, store , components: { App }, template: '<App/>' })
** npm run dev启动测试**
配置完善store/index.js
在store下面的index.js添加*
mutationsx相当于java中实体类的set
getters相当于get
> userInfo可以存入会话的sessionStorage里面 > **sessionStorage中只能存字符串 不能存入对象所以我们存入序列化 jons串:** > **sessionStorage.setItem("userInfo",JSON.stringify(userInfo))** > 会话获取 > **sessionStorage.getInte(userInfo)** > token可以存入浏览器的localStorage里面 > localStorage.setItem("token",token) > token获取: > localStorage.getItem("token") import Vue from 'vue' import Vuex from 'vuex' Vue.use(Vuex) export default new Vuex.Store({ //定义全局参数 其他页面可以直接获取state里面的内容 state: { token: '', //方法一 localStorage.getItem("token") //反序列化获取session会话中的 userInfo对象 userInfo:JSON.parse(sessionStorage.getItem("userInfo")) }, mutations: { //相当于实体类的set SET_TOKEN:(state,token)=>{ state.token=token//将传入的token赋值 给state的token //同时可以存入浏览器的localStorage里面 localStorage.setItem("token",token) }, SET_USERINFO:(state,userInfo)=>{ state.userInfo=userInfo//将传入的tuserInfo赋值 给state的userInfo //同时可以存入会话的sessionStorage里面 sessionStorage中只能存字符串 不能存入对象所以我们存入序列化 jons串 sessionStorage.setItem("userInfo",JSON.stringify(userInfo)) }, //删除token及userInfo REMOVE_INFO:(state)=>{ state.token = ''; state.userInfo = {}; localStorage.setItem("token",'') sessionStorage.setItem("userInfo",JSON.stringify('')) } }, getters: { //相当于get //配置一个getUser可以直接获取已经反序列化对象的一个userInfo getUser: state=>{ return state.userInfo; },getToken: state=>{ return state.token; } }, actions: { }, modules: { } })
在Login.vue中添加
_this.$axios.post("http://localhost:8081/login", _this.ruleForm).then(res => { console.log(res) const jwt = res.headers['authorization']; const userInfo = res.data.data _this.$store.commit('SET_TOKEN', token) _this.$store.commit('SET_USERINFO', userInfo) }) <template> <div> <el-container> <el-header> <img class="mlogo" src="../assets/logo.jpg" alt="logo图片" /> </el-header> <el-main> <el-form :model="ruleForm" :rules="rules" ref="ruleForm" label-width="100px" class="demo-ruleForm"> <el-form-item label="用户姓名" prop="username"> <el-input v-model="ruleForm.username"></el-input> </el-form-item> <el-form-item label="用户密码" prop="password"> <el-input v-model="ruleForm.password"></el-input> </el-form-item> <el-form-item> <el-button type="primary" @click="submitForm('ruleForm')">立即创建</el-button> <el-button @click="resetForm('ruleForm')">重置</el-button> </el-form-item> </el-form> </el-main> </el-container> </div> </template> <script> export default { name: "Login", data () { return { ruleForm: { username: 'admin', password: '111111' }, rules: { username: [ { required: true, message: '请输入用户名称', trigger: 'blur' }, { min: 3, max: 15, message: '长度在 3 到 15 个字符', trigger: 'blur' } ], password: [ { required: true, message: '请选择密码', trigger: 'blur' } ] } }; }, methods: { submitForm (formName) { this.$refs[formName].validate((valid) => { if (valid) { const _this = this;//获取整个vue的this console.log("校验成功") // alert('submit!'); _this.$axios.post("http://localhost:8081/login", _this.ruleForm).then(res => { console.log(res) const jwt = res.headers['authorization']; const userInfo = res.data.data //存储(共享)全局变量jwt和userInfo _this.$store.commit("SET_TOKEN", jwt); _this.$store.commit("SET_USERINFO", userInfo); //获取token和getUser // console.log(_this.$store.getters.getToken) // console.log(_this.$store.getters.getUser) }) } else { console.log('error submit!!'); return false; } }); }, resetForm (formName) { this.$refs[formName].resetFields(); } } } </script> <style scoped> .el-header, .el-footer { background-color: #b3c0d1; color: #333; text-align: center; line-height: 60px; } .el-main { /* background-color: #e9eef3; */ color: #333; text-align: center; line-height: 160px; } .mlogo { height: 80%; } .demo-ruleForm { max-width: 500px; margin: 0 auto; } </style>
main.js中引入
// 引入自定义axios.js
import “./axios.js”
完善axios.js
// 引入axios依赖
import axios from ‘axios’
// 引入element-ui依赖
import Element from ‘element-ui’
import store from ‘./store’;
// 引入路由
import router from ‘./router’
var s=window.location.toString();
var s1=s.substr(7,s.length);
var s2=s1.indexOf("/");
s=s.substr(0,8+s2);
var a = “http://localhost:8081/”;//获取连接前缀相当于 http://localhost:8081/
//配置默认前缀
axios.defaults.baseURL= a
//配置前置拦截
axios.interceptors.request.use(config => {
return config
})
//配置后置拦截
axios.interceptors.response.use(response=>{
let res = response.data;
if(res.code == 200){
return response
}else{
Element.Message.error(“操作错了哦”,{duration : 2*1000})
//返回一个异常提示就不会继续往下走了 不+的话 res=>的里面 还是会继续走的
return Promise.reject(response.data.msg)
}
// 捕获并处理后台异常信息
},error=>{
// 使得异常信息更加友好
console.log(error)
if (error.response.data) { //data不为空时
error.message = error.response.data.msg
console.log("-------------------------")
console.log(error.message)
console.log("-------------------------")
}
if(error.response.status == 401){
store.commit(‘REMOVE_INFO’)//清空token userinfo
router.push("/login") //跳转登录页面
}
Element.Message.error(error.message)
return Promise.reject(error)
}
)
npm run dev运行效果
打开AccountController
要先打开在logout方法里面返回一个Result 不然会报错
如果报错了这个需要先安装redis并且启动
https://www.cnblogs.com/pretty-sunshine/p/10615287.html
完善配置Header组件
<template> <div class="m-content"> <h3>欢迎来到我的博客世界</h3> <div class="block"> <div class="block"> <el-avatar :size="50" :src="user.avatar"></el-avatar> </div> <div>{{user.username}}</div> <div class="maction"> <span> <el-link>主页</el-link> </span> <el-divider direction="vertical"></el-divider> <span> <el-link type="success">发表博客</el-link> </span> <el-divider direction="vertical"></el-divider> <span v-show="!hasLogin"> <el-link type="primary" @click="login">登录</el-link> </span> <span v-show="hasLogin"> <el-link type="danger" @click="logout">退出</el-link> </span> </div> </div> </div> </template> <script> export default { name: "Header" , data () { return { user: { username: '请先登录', avatar: '../assets/logo.png' }, hasLogin: false } }, methods: { //退出操作 logout () { const _this = this //首先调用后端logout接口(因该接口需要认证权限,所以需要传入token) //其次调用$store清除用户信息及token _this.$axios.get("/logout", { headers: { "Authorization": localStorage.getItem("token") } }).then(res => { _this.$store.commit("REMOVE_INFO") _this.$router.push("/login") }) }, login () { //跳转登录页面进行登录 this.$router.push("/login") } }, //页面创建时即会调用,进而获取用户信息 created () { console.log("=======123=") console.log(this.$store.getters.getUser) if (this.$store.getters.getUser.username) {//如果username不为空 this.user.username = this.$store.getters.getUser.username this.user.avatar = this.$store.getters.getUser.avatar //判断是登录状态还是非登录显示 退出按钮或者登录按钮 this.hasLogin = true; } } } </script> <style> .m-content { max-width: 960px; margin: 0 auto; text-align: center; } .maction { } </style>
运行项目可以自行测试登录退出功能
完善blogs.vue
先给实体类Blog加上JsonFormat
@JsonFormat(pattern = “yyyy-MM-dd HH:mm:ss”)
private LocalDateTime created;
完善Blogs.vue
<h4> <router-link :to="{ name: 'BlogDetail', params: {blogid: blog.id}}">{{blog.title}}</router-link> </h4> <p>{{blog.description}}</p> </el-card> </el-timeline-item> </el-timeline> <el-pagination class="mage" background layout="prev, pager, next" :current-page="currentPage" :page-size="pageSize" :total="total" @current-change=page> </el-pagination> </div>
基于Vue的markdown编辑器mavon-editor
cnpm install mavon-editor --save
然后在main.js中全局注册:
// 全局注册
import mavonEditor from ‘mavon-editor’
import ‘mavon-editor/dist/css/index.css’
// use
Vue.use(mavonEditor)
// The Vue build version to load with the import
command

// 引入element-ui依赖
import Element from ‘element-ui’
import “element-ui/lib/theme-chalk/index.css”
// 引入axios依赖
import axios from ‘axios’
// 引入自定义axios.js

Vue.config.productionTip = false
/* eslint-disable no-new */
new Vue({
el: ‘#app’,
router,
store ,
components: { App },
template: ‘’
})
编写BlogEdit.vue
<template> <div> <Header></Header> <div class="m-content"> <el-form :model="ruleForm" :rules="rules" ref="ruleForm" label-width="100px" class="demo-ruleForm"> <el-form-item label="标题" prop="title"> <el-input v-model="ruleForm.title"></el-input> </el-form-item> <el-form-item label="摘要" prop="description"> <el-input type="textarea" v-model="ruleForm.description"></el-input> </el-form-item> <el-form-item label="内容" prop="content"> <mavon-editor v-model="ruleForm.content"></mavon-editor> </el-form-item> <el-form-item> <el-button type="primary" @click="submitForm('ruleForm')">立即创建</el-button> <el-button @click="resetForm('ruleForm')">重置</el-button> </el-form-item> </el-form> </div> </div> </template> <script> import Header from "../components/Header"; export default { name: "BlogEdit", components: { Header }, data () { return { ruleForm: { id: '', title: '', description: '', content: '' }, rules: { title: [ { required: true, message: '请输入标题', trigger: 'blur' }, { min: 3, max: 5, message: '长度在 3 到 15 个字符', trigger: 'blur' } ], description: [ { required: true, message: '请输入摘要', trigger: 'blur' }, ], content: [ { required: true, message: '请输入内容', trigger: 'blur' }, ] } }; }, methods: { submitForm (formName) { this.$refs[formName].validate((valid) => { if (valid) { const _this = this this.$axios.post('/blog/edit', this.ruleForm, { headers: { "Authorization": localStorage.getItem("token") } }).then(res => { _this.$alert('操作成功', '提示', { confirmButtonText: '确定', callback: action => { _this.$router.push("/blogs") } }); }) } else { console.log('error submit!!'); return false; } }); }, resetForm (formName) { this.$refs[formName].resetFields(); } }, created () { //获取动态路由的 blogid const blogId = this.$route.params.blogid console.log(blogId) const _this = this if (blogId) { this.$axios.get("/blog/" + blogId).then(res => { console.log(res) const blog = res.data.data _this.ruleForm.id = blog.id _this.ruleForm.title = blog.title _this.ruleForm.description = blog.description _this.ruleForm.content = blog.content }) } } } </script> <style scoped> .m-content { text-align: center; } </style>
运行效果
编辑:
博客详情中需要回显博客信息,然后有个问题就是,后端传过来的是博客内容是markdown格式的内容,我们需要进行渲染然后显示出来,这里我们使用一个插件markdown-it,用于解析md文档,然后导入github-markdown-c,所谓md的样式。
# 用于解析md文档 cnpm install markdown-it --save # md样式 cnpm install github-markdown-css
然后就可以在需要渲染的地方使用:
viewsBlogDetail.vue
</el-link> <el-divider></el-divider> <div class="markdown-body" v-html="blog.content"></div> </div>
页面已经开发完毕之后,我们来控制一下哪些页面是需要登录之后才能跳转的,如果未登录访问就直接重定向到登录页面,因此我们在src目录下定义一个js文件:
//配置一个路由前置拦截 rounter是路由
srcpermission.js
import router from “./router”;
// 路由判断登录 根据路由配置文件的参数
router.beforeEach((to, from, next) => {
if (to.matched.some(record => record.meta.requireAuth)) { // 判断该路由是否需要登录权限
const token = localStorage.getItem(“token”)
console.log("------------" + token)
if (token) { // 判断当前的token是否存在 ; 登录存入的token
if (to.path === ‘/login’) {
} else {
next()
}
} else {
next({
path: ‘/login’
})
}
} else {
next()
}
})
通过之前我们再定义页面路由时候的的meta信息,指定requireAuth: true,需要登录才能访问,因此这里我们在每次路由之前(router.beforeEach)判断token的状态,觉得是否需要跳转到登录页面。
meta: {
requireAuth: true
}
{ path: '/blog/add', // 注意放在 path: '/blog/:blogId'之前 name: 'BlogAdd', meta: { requireAuth: true }, component: BlogEdit },{ path: '/blog/:blogid/edit', name: 'BlogEdit', component: BlogEdit, meta: { requireAuth: true } import Vue from 'vue' import Router from 'vue-router' import HelloWorld from '@/components/HelloWorld' import Demo from '@/views/Demo' import Login from '@/views/Login' import Blogs from '@/views/Blogs' import BlogEdit from '@/views/BlogEdit' import BlogDetail from '@/views/BlogDetail' Vue.use(Router) export default new Router({ routes: [ { path: '/', name: 'Index', redirect:{name : "Blogs"} }, { path: '/blogs', name: 'Blogs', component: Blogs },{ path: '/Login', name: 'Login', component: Login },{ path: '/blog/add', name: 'BlogEdit', component: BlogEdit, meta: { requireAuth: true } }, { path: '/Demo', name: 'Demo', component: Demo },{ path: '/blog/:blogid', name: 'BlogDetail', component: BlogDetail } ,{ path: '/blog/:blogid/edit', name: 'BlogEdit', component: BlogEdit, meta: { requireAuth: true } } ]})
然后我们再main.js中import我们的permission.js
添加: import ‘./permission.js’ // 路由拦截
// The Vue build version to load with the `import` command // (runtime-only or standalone) has been set in webpack.base.conf with an alias. import Vue from 'vue' import App from './App' // 存储 import store from './store' // 路由 import router from './router' // 引入element-ui依赖 import Element from 'element-ui' import "element-ui/lib/theme-chalk/index.css" // 引入axios依赖 import axios from 'axios' // 引入自定义axios.js import "./axios.js" import './permission.js' // 路由拦截 //mavonEditor import mavonEditor from 'mavon-editor' import 'mavon-editor/dist/css/index.css' //引用全局 Vue.prototype.$axios = axios // use Vue.use(mavonEditor) Vue.use(Element) Vue.config.productionTip = false /* eslint-disable no-new */ new Vue({ el: '#app', router, store , components: { App }, template: '<App/>' })
