Idea工具使用Maven多Profile运行
示例如下:
SpringBoot在两个Profile下分别连接两个不同的数据库PostgreSQL和MySQL
Maven在两个Profile下分别依赖PostgreSQL和MySQL的驱动
数据库及数据准备见:https://blog.csdn.net/liwenyang1992/article/details/120311490
application.properties文件如下:使用@变量@作为配置占位符
#业务变量,观察打包是否被替换 business.environment=@project.environment@ server.port=8080 server.servlet.context-path=/maven #MyBatis配置 mybatis.configuration.map-underscore-to-camel-case=true mybatis.mapper-locations=classpath:mapper/*.xml #数据库连接配置 spring.datasource.driver-class-name=@datasource.driver@ spring.datasource.url= @datasource.url@ spring.datasource.username=@datasource.username@ spring.datasource.password=@datasource.password@
VO、Dao及Mapper文件准备见:https://blog.csdn.net/liwenyang1992/article/details/120311490
BookController文件:
package com.lwy.it.book.controller; import com.lwy.it.book.dao.BookDao; import com.lwy.it.book.vo.BookVO; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.web.bind.annotation.GetMapping; import org.springframework.web.bind.annotation.RestController; import java.util.List; @RestController public class BookController { @Autowired private BookDao bookDao; @GetMapping("/list") public List<BookVO> findAllBook() { List<BookVO> list = bookDao.findAllBook(); System.out.println(bookDao.findAllBook()); return list; } }
多profile的pom.xml文件如下:
<?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.4.11</version> <relativePath/> </parent> <groupId>com.lwy.it</groupId> <artifactId>maven-profile</artifactId> <version>0.0.1-SNAPSHOT</version> <name>maven-profile</name> <description>Demo project for Spring Boot</description> <properties> <java.version>1.8</java.version> </properties> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>org.mybatis.spring.boot</groupId> <artifactId>mybatis-spring-boot-starter</artifactId> <version>2.1.4</version> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-configuration-processor</artifactId> <optional>true</optional> </dependency> <dependency> <groupId>org.projectlombok</groupId> <artifactId>lombok</artifactId> <optional>true</optional> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency> </dependencies> <profiles> <profile> <id>mysql</id> <properties> <project.environment>mysql</project.environment> <datasource.url>jdbc:mysql://localhost:3306/goodsdb?allowMultiQueries=true&serverTimezone=GMT&characterEncoding=UTF-8</datasource.url> <datasource.username>root</datasource.username> <datasource.password>123456</datasource.password> <datasource.driver>com.mysql.cj.jdbc.Driver</datasource.driver> </properties> <dependencies> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <scope>runtime</scope> </dependency> </dependencies> </profile> <profile> <id>pgsql</id> <properties> <project.environment>pgsql</project.environment> <datasource.url>jdbc:postgresql://localhost:5432/goodsdb?sslmode=disable</datasource.url> <datasource.username>postgres</datasource.username> <datasource.password>123456</datasource.password> <datasource.driver>org.postgresql.Driver</datasource.driver> </properties> <dependencies> <dependency> <groupId>org.postgresql</groupId> <artifactId>postgresql</artifactId> <scope>runtime</scope> </dependency> </dependencies> </profile> </profiles> <build> <resources> <resource> <filtering>true</filtering> <directory>src/main/resources</directory> </resource> </resources> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> <configuration> <excludes> <exclude> <groupId>org.projectlombok</groupId> <artifactId>lombok</artifactId> </exclude> </excludes> </configuration> </plugin> </plugins> </build> </project>
占位符变量替换生效,则必须添加:
<resources> <resource> <filtering>true</filtering> <directory>src/main/resources</directory> </resource> </resources>
若使用Maven插件切换Profile,则无需添加默认profile,否则插件切换不生效。
<activation> <activeByDefault>true</activeByDefault> </activation>
测试验证:
profile选择mysql,Reimport Maven,访问http://localhost:8080/maven/list
输出:
[BookVO(bookId=1, bookName=安徒生童话, bookPrice=99.99), BookVO(bookId=2, bookName=MySQL实战教程, bookPrice=88.88)]
profile选择pgsql,Reimport Maven,访问http://localhost:8080/maven/list
输出:
[BookVO(bookId=1, bookName=格林童话, bookPrice=100.01), BookVO(bookId=2, bookName=PostgreSQL实战, bookPrice=66.66)]
切换操作如下图:
