玄学yml,被@ActiveProfiles注解误导

@ActiveProfiles("')来自何处？怎么用？（不要被它的名字误导）

ActiveProfiles is a class-level annotation that is used to declare which active bean definition profiles should be used when loading an ApplicationContext for test classes. 

它只能用在测试环境中，其他地方没有用。

第一次用这个注解，在test环境中，src/test/resoutces写下了这样的application.yml

看起来非常灵活，

rpcconfig:
    dataconfig:
        uniformconfig:
            client-reconnect-try: 20
            #客户端连接超时时间（单位：毫秒
            client-connect-timeout: 5000
            #token最大生命期(单位：毫秒)
            token-life: 1800000
            client-write-idle: 3000
            server-read-idle: 8000
        serviceconfig:
            #自定义配置的服务数量不确定
            - name: customer
              ip: 127.0.0.1
              port: 8001
            - name: account
              ip: 127.0.0.1
              port: 8002
            - name: dao
              ip: 127.0.0.1
              port: 8003
            - name: testsso
              ip: 127.0.0.1
              port: 8004
    ssoconfig:
        - leader-service: customer
          login-addr: /customer/login
          visitor-name: httpserver
          group-members:
           - account
           - testssos

在src/main/java的configuration bean中随意指定profile:

@Configuration
@ActiveProfiles("mytest")--------------------------------------------------//在application.yml任意profile好像都可以指定，写起来很溜
@ConfigurationProperties(prefix="testdata")

然而，这种写法只能在测试环境中应用。

@RunWith(SpringRunner.class)
@SpringBootTest

public class Testymldemo {
    Logger log = LoggerFactory.getLogger(Testymldemo.class);

    @Autowired
    private Uniformconfig ufc;
    
    @Autowired
    private Ssoconfig scf;
    
    @Autowired
    private TestConf tf;
    
    @Autowired
    private Serviceconfig serviceconfig;
    
    @Autowired
    private TestNetConf tncf;



    @Test
    public void testuniformconfig(){
        //this.resource
        //System.out.println(y0.getUniformconfig().getClientConnectTimeout());
        System.out.println(ufc.toString());
        System.out.println(scf.getSsoconfig());
        System.out.println(tf.getAnimals()+" "+tf.getMap()+" "+tf.getBigmap());
        System.out.println(serviceconfig.toString());
        System.out.println(tncf);
    }

如果将@ActiveProfiles用在正式运行的环境中，springboot直接忽略，然后达不到预期的“灵活”目的；

在正式运行环境中，怎么实现profile切换？

一种方法：

spring:
    profiles:
        active: dev     #在这里修改，，dev,,test,,....
registry:
    serverip: 127.0.0.1
    serverport: 9090
---
spring:
    profiles: test
registry:
    serverip: 127.0.0.1
    serverport: 9091
---
spring:
    profiles: dev
registry:
    serverip: 127.0.0.1
    serverport: 9092
