#### 对基础module高并发测试 ####

*   *  Jmeter压测测试
     *  Jmeter压测结论
     *  80新建加入

### 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>
            
            <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
