本文探讨了服务间调用时出现的Feign超时错误，详细解析了错误原因，包括ribbon和hystrix的配置不当，并提供了具体的解决方案，如调整ribbon的超时时间和启用hystrix熔断机制。

问题介绍：

服务之间调用报错超时，截取部分报错，Read timed out executing POST http://******

原因及解决办法：

明显可以看到是http请求报错超时，feign的调用分两层，ribbon的调用和hystrix的调用，高版本的hystrix默认是关闭的，所以在application.properties配置文件中设置ribbon即可

#请求处理的超时时间
ribbon.ReadTimeout: 120000
#请求连接的超时时间
ribbon.ConnectTimeout: 30000
如果开启hystrix，hystrix的超时报错如下图：

FeignDemo#demo() timed-out and no fallback available。和ribbon超时报错还是有区别的

解决办法：

feign.hystrix.enabled: true
hystrix 熔断机制
hystrix:
shareSecurityContext: true
command:
default:
circuitBreaker:
sleepWindowInMilliseconds: 100000
forceClosed: true
execution:
isolation:
thread:
timeoutInMilliseconds: 600000
