# 配置规则
#所以应该叫bootstrap.yml

      # 配置规则里的${profile}

      # 配置规则里的${label},label 是分支,不是路径！
      # label: test

      # 找到配置的方式二

@RunWith(SpringRunner.class)
@SpringBootTest
public class MicroWeatherConfigClientApplicationTests {

    @Test
    public void contextLoads() {
        Assert.assertEquals("1.0",version);
    }

}

rabbitmq 的bus依赖添加
config server 和client的版本应该对应起来才可以

## 变量名可能会变，利用自动提示可以找到对应的正确配置变量 （输入management.endpoints 找到默认包含一个[health,info]数组的变量，修改为"*"）
management:
  endpoints:
    web:
      暴露所有接口
      expose: "*"

@RestController
@RequestMapping("/env")
@RefreshScope // 加入这个注解自动刷新配置
public class EnvController {

    @Value("${env}")
    private String env;

    @GetMapping("/print")
    public String print() {
        return env;
    }
}
}

@Data
@Component
@ConfigurationProperties("girl")
@RefreshScope // 加入这个注解自动刷新配置
public class GirlConfig {

    private String name;

    private Integer age;
}
