It is subject to change based on the remote Feign使用优化 Feign底层发起http请求，依赖于其它的框架。其底层客户端实现包括： •URLConnection：默认实现，不支持连接池 •Apache HttpClient ：支持连接池 •OKHttp：支持连接池 因此提高Feign的性能主要手段就是使用连接池代替默认的URLConnection。这里我们用Apache的HttpClient来演示。 Feign client logging helps us to have a better view of the requests that have been made. To enable logging, we need to set the Spring Boot logging level to DEBUG for the class or package that contains our feign client in the application. Consider using `OkHttp` In this tutorial, you learned how to configure timeout settings for Java Feign clients using both YAML properties and a custom configuration class. netflix. Default(100, 1000, 3)) . When you're defining this timeout you should add both of them, otherwise, the application will not consider them and will use 对于这个问题网上有很多相关资料，大体上有两种方案，一种是通过设置 ribbon 的超时时间（因为 Feign 是基于 ribbon 来实现的，所以通过 ribbon 的超时时间设置也能达到目的），一种是直接设置 Feign 的超时时间，我将会在下边的篇幅里分别说一下如何通过application. 12. It is subject to change based on the remote The connect and read timeout configuration in the OkHttpClient is overwritten by feign in the code below when no options are set in feign.

Options supports only connect and read timeout not connection request timeout. Wouldn't it be a good idea if this would be a prototyped bean? Then I could autowire this bean and set target manually and it is guarenteed that the configuration of my manually created feign client is the same as the one of spring. client(new * The default value is 10 seconds. retryer(Retryer. errorDecoder(new EdocErrorDecoder(objectMapper())) . The time taken to perform a lookup and to receive such a packet causes a significant part of this delay. .
