Idea编译器Spring Profile与Maven Profile联动
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
[email protected]@
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
[email protected]@
spring.datasource.url= @datasource.url@

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：

xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd">

占位符变量替换生效，则必须添加：
<resources>
<resource>
<filtering>truefiltering>
<directory>src/main/resourcesdirectory>

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>

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：
改进点
由于数据库配置信息密级等级较高，即使是本地测试也不适合写在pom.xml文件中，所以通过启动时传递jvm参数的方式进行修改：
application.properties
#业务变量，观察打包是否被替换
[email protected]@
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
[email protected]@
spring.datasource.url= @datasource.url@
[email protected]@
spring.datasource.password=
pom.xml文件已经去掉密码信息：

编辑启动项，添加spring.datasource.password的值，如图
重新clean compile ，运行
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)]
