问题描述：进行解析Excel 由于控制层访问微服务时，微服务运行时间过长导致 出现Read timed out的异常。
具体异常如下：

<1>通过日志发现 当控制层访问微服务的响应时间超过5秒
例:
2017-04-14 14:07:28.684 INFO 25898 --- [nio-8081-exec-2] com.zhongqi.controller.ApplyController : 入库程序运行时间： 5192ms;
就会出现 :
Read timed out executing POST http://match-manager-apply/userApply/addUserCertificateList?matchId=9] with root cause
<2>通过查阅资料发现是很多博主都说是
例如:
http://www.itmuch.com/spring-cloud-feign-ribbon-first-request-fail/
通过使用多次发现并不是断路器的问题.
通过查阅博客:发现时ribbon的配置问题
详细测试步骤参考：http://stackoverflow.com/questions/39154613/netflix-ribbon-and-hystrix-timeout
通过查找源码发现了如下的配置文件
源码定义如下
在控制层 配置文件：application.properties
添加
spring.cloud.loadbalancer.retry.enabled=true
ribbon.ReadTimeout=60000
ribbon.ConnectTimeout=60000[/code]
就可以解决访问超时的问题。
具体异常如下：

<1>通过日志发现 当控制层访问微服务的响应时间超过5秒
例:
2017-04-14 14:07:28.684 INFO 25898 --- [nio-8081-exec-2] com.zhongqi.controller.ApplyController : 入库程序运行时间： 5192ms;
就会出现 :
Read timed out executing POST http://match-manager-apply/userApply/addUserCertificateList?matchId=9] with root cause
<2>通过查阅资料发现是很多博主都说是
hystrix断路器的配置问题:
例如:
http://www.itmuch.com/spring-cloud-feign-ribbon-first-request-fail/
通过使用多次发现并不是断路器的问题.
通过查阅博客:发现时ribbon的配置问题
详细测试步骤参考：http://stackoverflow.com/questions/39154613/netflix-ribbon-and-hystrix-timeout
通过查找源码发现了如下的配置文件
源码定义如下
hystrix.command.default.execution.isolation.thread.timeoutInMilliseconds：断路器的超时时间需要大于ribbon的超时时间，不然不会触发重试。
hello-service.ribbon.ConnectTimeout：请求连接的超时时间
hello-service.ribbon.ReadTimeout：请求处理的超时时间
hello-service.ribbon.OkToRetryOnAllOperations：对所有操作请求都进行重试
hello-service.ribbon.MaxAutoRetriesNextServer：切换实例的重试次数
hello-service.ribbon.MaxAutoRetries：对当前实例的重试次数
在控制层 配置文件：application.properties
添加
hystrix.command.default.execution.isolation.thread.timeoutInMilliseconds=6000
spring.cloud.loadbalancer.retry.enabled=true
ribbon.ReadTimeout=60000
ribbon.ConnectTimeout=60000[/code]
就可以解决访问超时的问题。
