压测springCloud报错ThreadPoolExecutor [Running, pool size = 10, active threads = 10, queued tasks=0错误）

发生场景

1、用户登陆压测场景1，设置用户数10进行并发操作：压力都可正常登陆成功无异常情况
2、用户登陆压测场景2，设置用户数20进行并发操作：压力测试过程出现错误率5%异常错误，根据异常情况去后端查看日志
3、核查发现有个服务异常hhh-auth 异常日志内容提示连接池设置少，日志如下，核查数据库连接的配置文件，未发现设置10的最大连接数，跟线程数。

解决方案

我能解决这个问题是来源于某个大佬的这篇文章 Spring Cloud Hystrix 线程池队列配置。

feign.hystrix.enabled=true
#并发执行的最大线程数，默认10
hystrix.threadpool.default.coreSize=50
#BlockingQueue的最大队列数，默认值-1
hystrix.threadpool.default.maxQueueSize=1500
#即使maxQueueSize没有达到，达到queueSizeRejectionThreshold该值后，请求也会被拒绝，默认值5
hystrix.threadpool.default.queueSizeRejectionThreshold=1000

注意：如果要调整队列，必须同时修改maxQueueSize和queueSizeRejectionThreshold属性的值，否则都会出现异常！因为queueSizeRejectionThreshold 官方的默认值只有5。

附：报服务调用异常说明使用的是分布式系统，如果没有引用Hystrix 包的话，首先请引用Hystrix 包

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

在启动类上加入注解@EnableHystrixDashboard

@EnableDiscoveryClient
@EnableFeignClients
@SpringBootApplication
@EnableHystrixDashboard
public class HhhAuthApplication {}
