在使用Spring Cloud的時候遇見了 這個異常：

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

組件中使用了 Eureka? 、Feign ,因為Feign中引用了Ribbon，所以就沒有顯示引用jar.

再往上找到了各種遇見這個問題的解決方案，但是在這個版本號之內已經沒有了：

ribbon.connect-timeout和ribbon.read-timeout 這兩個變量的定義，所以在看了官方文檔之后：

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

這兩個參數就可以解決timeout的問題。
