3、YML

  1. server:
  2.   port: 8001
  4. spring:
  5.   application:
  6.     name: cloud-provider-hystrix-payment
  8. eureka:
  9.   client:
  10.     register-with-eureka: true
  11.     fetch-registry: true
  12.     service-url:
  13.       #defaultZone: http://eureka7001.com:7001/eureka,http://eureka7002.com:7002/eureka
  14.       defaultZone: http://eureka7001.com:7001/eureka

4、主启动

5、业务类

  1. @Service
  2. public class PaymentService {
  3.     /**
  4.      * 正常访问
  5.      * @param id
  6.      * @return
  7.      */
  8.     public String paymentInfo_ok(Integer id){
  9.         return "线程池:"+Thread.currentThread().getName()+"paymentInfo_ok,id"+id+"\t"+"O(∩_∩)O哈哈~";
  10.     }
  11.     public String paymentInfo_TimeOut(Integer id){
  12.         try{
  13.             TimeUnit.SECONDS.sleep(3);
  14.         }catch (InterruptedException e){
  15.             e.printStackTrace();
  16.         }
  17.         return "线程池:"+Thread.currentThread().getName()+"paymentInfo_TimeOut,id"+id+"O(∩_∩)O哈哈~"+"耗时3秒钟";
  18.     }
  19. }
  1. @RestController
  2. @Slf4j
  3. public class PaymentController {
  4.     @Resource
  5.     private PaymentService paymentService;
  7.     @Value("${server.port}")
  8.     private String serverPort;
  10.     @GetMapping("/payment/hystrix/ok/{id}")
  11.     public String paymentInfo_OK(@PathVariable("id") Integer id){
  12.         String result = paymentService.paymentInfo_ok(id);
  13.         log.info("*****result"+result);
  14.         return result;
  15.     }
  16.     @GetMapping("/payment/hystrix/timeout/{id}")
  17.     public String paymentInfo_TimeOut(@PathVariable("id") Integer id){
  18.         String result = paymentService.paymentInfo_TimeOut(id);
  19.         log.info("*****result"+result);
  20.         return result;
  21.     }
  23. }

6、正常测试

启动eureka7001
启动cloud-provider-hystrix-payment8001
访问
删除Module均OK

7、压力测试

开启Jmeter
然后两个都在转圈圈了

tomcat的默认工作线程数被打满了，
