如何获取spring aop代理类的被代理类或者说是获取目标类

@RestController
public class TestController {
    @Autowired
    private ConsulRetryRegistry consulRetryRegistry;


    @RequestMapping("server/offline")
    public String doDeRegister(){

        ConsulRetryRegistry singletonTarget =(ConsulRetryRegistry) AopProxyUtils.getSingletonTarget(consulRetryRegistry);
        singletonTarget.retryThread.doRegister();
        return "ok";

    }
}

注意：当直接注入ConsulRetryRegistry时，注入的是代理类，而代理类中的 retryThread属性字段是空的，所以需要获取被代理类，通过spring自带的util:  AopProxyUtils
