Jmeter压测测试

①开启Jmeter，来20000个并发压死8001，20000个请求都去访问paymentInfo_TimeOut服务。 ②再来一个访问

http://localhost:8001/payment/hystrix/ok/31 http://localhost:8001/payment/hystrix/timeout/31

③会发现本来ok是不应该转圈圈的，可是当我们去访问ok的时候也在转圈，这是因为tomcat的默认的工作线程数被打满了，没有多余的线程来分解压力和处理。

Jmeter压测结论

上面还是服务提供者8001自己测试，假如此时外部的消费者80也来访问，那消费者只能干等，最终导致消费端80不满意，服务端8001直接被拖死

80新建加入

1、新建cloud-consumer-feign-hystrix-order80 2、改pom

<dependencies> <!--新增hystrix--> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-netflix-hystrix</artifactId> </dependency> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-openfeign</artifactId> </dependency> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId> </dependency> <dependency> <groupId>com.atguigu.springcloud</groupId> <artifactId>cloud-api-commons</artifactId> <version>${project.version}</version> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-actuator</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-devtools</artifactId> <scope>runtime</scope> <optional>true</optional> </dependency> <dependency> <groupId>org.projectlombok</groupId> <artifactId>lombok</artifactId> <optional>true</optional> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency> </dependencies>

3、写yml

server: port: 8001 spring: application: name: cloud-provider-hystrix-payment eureka: client: register-with-eureka: true #表识向注册中心注册自己 fetch-registry: true service-url: # defaultZone: http://eureka7002.com:7002/eureka/ 这里为了方便不用集群版本 defaultZone: http://eureka7001.com:7001/eureka/

4、主启动类

@SpringBootApplication @EnableFeignClients public class OrderHystrixMain80 { public static void main(String[] args) { SpringApplication.run(OrderHystrixMain80.class,args); } }

5、业务类 PaymentHystrixService

@Component @FeignClient(value = "CLOUD-PROVIDER-HYSTRIX-PAYMENT") public interface PaymentHystrixService { @GetMapping("/payment/hystrix/ok/{id}") public String paymentInfo_OK(@PathVariable("id") Integer id); @GetMapping("/payment/hystrix/timeout/{id}") public String paymentInfo_TimeOut(@PathVariable("id") Integer id); }

OrderHystrixController

@RestController @Slf4j public class OrderHystrixController { @Resource private PaymentHystrixService paymentHystrixService; @Value("${server.port}") private String serverPort; @GetMapping("/consumer/payment/hystrix/ok/{id}") public String paymentInfo_OK(@PathVariable("id") Integer id){ String result = paymentHystrixService.paymentInfo_OK(id); log.info("*******result:"+result); return result; } @GetMapping("/consumer/payment/hystrix/timeout/{id}") public String paymentInfo_TimeOut(@PathVariable("id") Integer id){ String result = paymentHystrixService.paymentInfo_TimeOut(id); log.info("*******result:"+result); return result; } }

6、正常测试

http://localhost/consumer/payment/hystrix/ok/31

7、高并发测试 1、2W个线程压8001的timeout方法 2、消费端80微服务再去访问正常的OK微服务8001地址 3、80要么转圈圈等待，要么消费端报超时错误
