在使用Spring Cloud的时候遇见了 这个异常：

feign.RetryableException: Read timed out executing POST xxxxxxat feign.FeignException.errorExecuting(FeignException.java:65)at feign.SynchronousMethodHandler.executeAndDecode(SynchronousMethodHandler.java:105)at feign.SynchronousMethodHandler.invoke(SynchronousMethodHandler.java:77)at feign.ReflectiveFeign$FeignInvocationHandler.invoke(ReflectiveFeign.java:102)at com.sun.proxy.$Proxy113.generateUserContract(Unknown Source)

spring boot :2.0.6.RELEASE

spring cloud :Finchley.SR2

组件中使用了 Eureka  、Feign ,因为Feign中引用了Ribbon，所以就没有显示引用jar.

再往上找到了各种遇见这个问题的解决方案，但是在这个版本号之内已经没有了：

ribbon.connect-timeout和ribbon.read-timeout 这两个变量的定义，所以在看了官方文档之后：

feign.client.config.default.connect-timeout=20000
feign.client.config.default.read-timeout=20000    

这两个参数就可以解决timeout的问题。
