只需要添加 bus（rabbitmq ）依赖和连接地址会自动开启自动刷新
访问 http://{ 配置中心地址 }/actuator/bus-refresh 触发自动刷新

重点：获取属性的属性类上必须要增加@RefreshScope 注解。

@RefreshScope
public class EnvController {
    @Value("${girl.age}")
    private String age;

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