Hystrix 服务降级二（客户端降级）

1:pom

      <!--  hystrix  -->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-hystrix</artifactId>
        </dependency>

2:yml

  hystrix:
    enabled: true

3:service

@Component
@FeignClient(value = "CLOUD-PAYMENT-HYSTRIX-SERVICE", fallback = PaymentServiceImpl.class)
public interface PaymentService {

    @GetMapping(value = "/payment/ok")
    BaseResult paymentInfo_OK();

    @RequestMapping("/payment/timeOut")
    BaseResult paymentInfo_TimeOut();
    
}

4:serviceImpl

@Component
public class PaymentServiceImpl implements PaymentService {
    @Override
    public BaseResult paymentInfo_OK() {
        Object obj = "PaymentServiceImpl paymentInfo_OK fall back";
        return new BaseResult(-1, "error", obj);
    }

    @Override
    public BaseResult paymentInfo_TimeOut() {
        Object obj = "PaymentServiceImpl paymentInfo_TimeOut fall back";
        return new BaseResult(-1, "error", obj);
    }
}

5:controller

    @RequestMapping("/timeOut")
    public BaseResult paymentInfo_TimeOut() {
        return paymentService.paymentInfo_TimeOut();
    }

调用timeOut接口

　　

{"code":-1,"message":"error","t":"PaymentServiceImpl paymentInfo_TimeOut fall back"}

　　一般使用该方式做降级处理
