Spring boot结合Maven实现不同环境的配置

配置文件层次：

pom.xml

 <build>
    <filters>
        <filter>src/main/resources/env/${profiles.active}/application.yml</filter>
    </filters>
    <!-- 替换${key}内容 -->
     <resources>
            <resource>
                <filtering>true</filtering>
                <!--要到达最底层目录-->
                <directory>src/main/resources/env/${profiles.active}</directory>
            </resource>
     </resources>
 </build> 
  
  
  
  
  
</project>

带有${key}的配置文件：

/Spring-Env/src/main/resources/application.yml

#激活的环境配置
spring:
  profiles:
    active: ${spring.profiles.active}
#端口
server: 
  port: ${server.port}

配置文件一：

src/main/resources/env/pro/application.yml

server:
  port: 8083
  env: pro
  
ftp: hello pro

spring:
  profiles:
    active: pro

配置文件二：

src/main/resources/env/dev/application.yml

server:
  port: 8084
  
ftp: hello dev

spring:
  profiles:
    active: dev

配置文件三：

src/main/resources/env/sit/application.yml

server:
  port: 8082
  env: sit
ftp: hello sit

spring:
  profiles:
    active: sit

运行Spring boot主程序即可实现！

测试程序：

@RestController
public class SampleController {
    
     @Autowired
     private  Environment env;
    
    @RequestMapping("/sample")
    public String sample(){
        
        return "spring boot success ! and profile is ==>"+
        env.getProperty("spring.profiles.active")+"=====>"+
        env.getProperty("ftp");
    }
}

maven打包：

mvn clean install -P pro

maven打包：

mvn clean install -P sit

 

注：maven打包也可以使用eclipse的maven插件
