3.yml文件

server:
  port: 8001


spring:
  application:
    name: cloud-provider-hystrix-payment


eureka:
  client:
    register-with-eureka: true
    fetch-registry: true
    service-url:
      defaultZone: http://eureka7001.com:7001/eureka

 

4.主启动类

@SpringBootApplication
@EnableEurekaClient
public class PaymentHystrixMain8001 {

    public static void main(String[] args) {
        SpringApplication.run(PaymentHystrixMain8001.class,args);
    }

}

 

5.业务类
service

@Service
public class PaymentService {

    /**
     * 正常访问
     * @param id
     * @return
     */
    public String paymentInfo_ok(Integer id){
        return "线程池:"+Thread.currentThread().getName()+" paymentInfo_ok, id :"+id+"\t"+"成功";
    }


    public String paymentInfo_timeout(Integer id){
        int time=3;
        try {
            TimeUnit.SECONDS.sleep(time);
        }catch (InterruptedException e){
            e.printStackTrace();
        }
        return "线程池:"+Thread.currentThread().getName()+" paymentInfo_timeout, id :"+id+"\t"+"耗时（秒): "+time;
    }


}

 

controller

@RestController
@Slf4j
public class PaymentController {

    @Resource
    private PaymentService paymentService;

    @Value("${server.port}")
    private String serverPort;

    /**
     * 正常访问
     * @param id
     * @return
     */
    @GetMapping("/payment/hystrix/ok/{id}")
    public String paymentInfo_ok(@PathVariable("id") Integer id){
        String result=paymentService.paymentInfo_ok(id);
        log.info("*******result:" +result);
        return  result;
    }

    /**
     * 超时
     * @param id
     * @return
     */
    @GetMapping("/payment/hystrix/timeout/{id}")
    public String paymentInfo_time(@PathVariable("id") Integer id){
        String result=paymentService.paymentInfo_timeout(id);
        log.info("*******result:" +result);
        return  result;
    }
}

 

6.测试
6.1启动eureka7001
6.2启动cloud-provider-hystrix-payment8001
6.3访问
success的方法：http://localhost:8001/payment/hystrix/ok/{id}

每次调用耗费3秒钟：http://localhost:8001/payment/hystrix/timeout/{id}
