Springboot 多环境配置

## 1. 前言
为方便开发和统一管理，项目切换环境统一由IDEA的maven插件可视化修改，不提供命令行方式，有兴趣请自行探索

## 2. 在项目Pom文件`project`标签下新增如下标签
```
	
    <profiles>
        <profile>
            <id>dev</id>
            <properties>
                <profileActive>dev</profileActive>
            </properties>
            <activation>
                
                <activeByDefault>true</activeByDefault>
            </activation>
        </profile>
        <profile>
            <id>test</id>
            <properties>
                <profileActive>test</profileActive>
            </properties>
        </profile>
        <profile>
            <id>prod</id>
            <properties>
                <profileActive>prod</profileActive>
            </properties>
        </profile>
    </profiles>
```

## 3. 修改配置文件
3.1 将不同环境的配置文件命名为application-{环境}文件
```
resources/
├── application-dev.yml
├── application-prod.yml
├── application-test.yml
└── application.yml
```

3.2 修改application.yml
```
# profileActive 为pom中properties标签声明的变量，如需修改记得同步修改，打包时会替换为变量标签里的值
spring:
  profiles:
    active: @profileActive@
```

3.3 修改maven引入的范围
```
       <resources>
            <resource>
                <directory>src/main/resources</directory>
				
                <filtering>true</filtering>
                <includes>
                    
                    <include>application-${profileActive}.yml</include>
                    <include>application.yml</include>
                    <include>**/*.xml</include>
                    <include>templates/**</include>
                </includes>
            </resource>
        </resources>
```
