建立Bilibili排行榜信息 JAVA

本文主要是介绍建立Bilibili排行榜信息 JAVA，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！

建立Bilibili排行榜信息

  • 建立数据库

    • image-20210930210133264

    • 导出的语句

      SET NAMES utf8mb4;
SET FOREIGN_KEY_CHECKS = 0;

-- ----------------------------
-- Table structure for bilibilirank
-- ----------------------------
DROP TABLE IF EXISTS `bilibilirank`;
CREATE TABLE `bilibilirank`  (
  `id` int(0) NOT NULL AUTO_INCREMENT COMMENT '主键',
  `rid` varchar(10) CHARACTER SET utf8mb4 COLLATE utf8mb4_bin NULL DEFAULT NULL COMMENT '分区类型',
  `aid` varchar(15) CHARACTER SET utf8mb4 COLLATE utf8mb4_bin NULL DEFAULT NULL COMMENT 'aid',
  `bvid` varchar(15) CHARACTER SET utf8mb4 COLLATE utf8mb4_bin NULL DEFAULT NULL COMMENT 'bid',
  `typename` varchar(100) CHARACTER SET utf8mb4 COLLATE utf8mb4_bin NULL DEFAULT NULL COMMENT '分区名字',
  `title` varchar(100) CHARACTER SET utf8mb4 COLLATE utf8mb4_bin NULL DEFAULT NULL COMMENT '视频标题',
  `play` varchar(255) CHARACTER SET utf8mb4 COLLATE utf8mb4_bin NULL DEFAULT NULL COMMENT '播放量',
  `review` varchar(20) CHARACTER SET utf8mb4 COLLATE utf8mb4_bin NULL DEFAULT NULL COMMENT '评论量',
  `favoritea` varchar(20) CHARACTER SET utf8mb4 COLLATE utf8mb4_bin NULL DEFAULT NULL COMMENT '收藏量',
  `author` varchar(20) CHARACTER SET utf8mb4 COLLATE utf8mb4_bin NULL DEFAULT NULL COMMENT '作者',
  `description` varchar(200) CHARACTER SET utf8mb4 COLLATE utf8mb4_bin NULL DEFAULT NULL COMMENT '简介',
  `create` varchar(50) CHARACTER SET utf8mb4 COLLATE utf8mb4_bin NULL DEFAULT NULL COMMENT '上传时间',
  `pic` varchar(100) CHARACTER SET utf8mb4 COLLATE utf8mb4_bin NULL DEFAULT NULL COMMENT '封面链接',
  PRIMARY KEY (`id`) USING BTREE
) ENGINE = InnoDB CHARACTER SET = utf8mb4 COLLATE = utf8mb4_bin ROW_FORMAT = Dynamic;

SET FOREIGN_KEY_CHECKS = 1;

  • 通过mybatis-plus逆向生成实体类

    • 默认 均会使用代码构造器和mysql

    • 生成效果如下

    • image-20210930212043923

  • 调整代码

    • Controller层设置为Springboot的测试类 执行主要方法（下面是测试代码）

    • package edu.sdut.bilibili.controller;


import edu.sdut.bilibili.service.impl.BilibilirankServiceImpl;
import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;

/**
 * <p>
 *  bilibiliRank排行榜 主控制类
 * </p>
 *
 * @author qingyun
 * @since 2021-09-30
 */
@SpringBootTest
public class BilibilirankController {

    @Autowired
    BilibilirankServiceImpl bilibilirankService;

    @Test
    public void testInset(){
        bilibilirankService.Insert();
    }
}

    • Service

    • package edu.sdut.bilibili.service.impl;

import edu.sdut.bilibili.entity.Bilibilirank;
import edu.sdut.bilibili.mapper.BilibilirankMapper;
import edu.sdut.bilibili.service.IBilibilirankService;
import com.baomidou.mybatisplus.extension.service.impl.ServiceImpl;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import javax.sql.DataSource;

/**
 * <p>
 *  服务实现类
 * </p>
 *
 * @author qingyun
 * @since 2021-09-30
 */
@Service
public class BilibilirankServiceImpl extends ServiceImpl<BilibilirankMapper, Bilibilirank> implements IBilibilirankService {

    @Autowired
    BilibilirankMapper bilibilirankMapper;

    public void Insert() {
        Bilibilirank bilibilirank = new Bilibilirank();
        bilibilirank.setAid("1");
        bilibilirankMapper.insert(bilibilirank);
    }
}

      修改主要逻辑代码

      package edu.sdut.bilibili.controller;


import edu.sdut.bilibili.entity.Bilibilirank;
import edu.sdut.bilibili.service.impl.BilibilirankServiceImpl;
import org.junit.jupiter.api.Test;

 */
@SpringBootTest
public class BilibilirankController {

    @Autowired
    BilibilirankServiceImpl bilibilirankService;

    @Test
    public void GetListBiliBiliRanks() {
        //获取所有的排行榜信息
        List<Bilibilirank> biliBiliRank = bilibilirankService.getBiliBiliRank();
        System.out.println(biliBiliRank);
    }
}


      package edu.sdut.bilibili.service.impl;

    @Autowired
    BilibilirankMapper bilibilirankMapper;

    @Override
    public List<Bilibilirank> getBiliBiliRank() {
        int low = 300; int row = 10;
        List<Bilibilirank> BiliBiliRankS = new ArrayList<>();
        for (int i = 1; i < low; i++) {
//            数据主体
            String InfoBody = HttpRequest.get("http://api.bilibili.com/x/web-interface/ranking/region?rid=" + i).body();
            JSONObject BiliBiliInfoBody = JSONUtil.parseObj(InfoBody);
            //有请求信息
            if (BiliBiliInfoBody.getInt("code")==0){
                //获取data
                JSONArray data = BiliBiliInfoBody.getJSONArray("data");
                for (int j = 0; j < row; j++) {
                    //建立 bilibilirank
                    Bilibilirank bilibilirank = new Bilibilirank();
                    JSONObject rows = data.getJSONObject(j);
                    if (rows == null){
                       continue;

                    bilibilirank.setRid(Integer.toString(j));
                    bilibilirank.setAid(rows.getStr("aid"));
                    bilibilirank.setBvid(rows.getStr("bvid"));
                    bilibilirank.setTypename(rows.getStr("typename"));
                    bilibilirank.setTitle(rows.getStr("title"));
                    bilibilirank.setPlay(rows.getStr("play"));
                    bilibilirank.setReview(rows.getStr("review"));
                    bilibilirank.setFavoritea(rows.getStr("favorite"));
                    bilibilirank.setAuthor(rows.getStr("author"));
                    bilibilirank.setDescription(rows.getStr("description"));
                    bilibilirank.setCreate(rows.getStr("create"));
                    bilibilirank.setPic(rows.getStr("pic"));
                    BiliBiliRankS.add(bilibilirank);
                }
            }

        }
        return BiliBiliRankS;
    }
}

      效果如下

      下面进行插入数据库操作，使用mybatis-plus的批量插入操作

      注：直接提供的批量插入并不是真的批量插入。读者请自行查找真正的批量插入
