Spring boot结合Maven实现不同环境的配置

配置文件层次：

     </filters>
     <!-- 替换${key}内容 -->

      </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
