springcloudfeign使用okhttp3 springcloudfeign使⽤okhttp3 在Feign中,Client是⼀个⾮常重要的组件,Feign最终发送Request请求以及接收Response响应都是由Client组件来完成的。Client在Feign源码中是⼀个接⼝,在默认情况下,Client的实现类是Client.Default。Client.Default是由HttpURLConnection来实现⽹络请求的。
但是通过查看源码org.springframework.cloud.openfeign.FeignAutoConfiguration发现有这个配置:@ConditionalOnMissingBean(okhttp3.OkHttpClient.class),大概意思就是如果没有OkHttpClient这个Bean,就启动这个配置,如果存在OkHttpCLient的Bean,则不启用这个配置。

这块结合feign替换okhttp3最好用feignClient()来实现,有几个配置跟你上面类似,例如OkHttpClient的自动注入,不赘述,大致如下: @Configuration @ConditionalOnClass({ OkHttpClient.class, Feign.class, ILoadBalancer.class }) @ConditionalOnProperty(value = "feign.okhttp.enabled", matchIfMissing = true) ...

1 SpringCloud 中 Feign 核心原理 如果不了解 SpringCloud 中 Feign 核心原理,不会真正的了解 SpringCloud 的性能优化和配置优化,也就不可能做到真正掌握 SpringCloud。 本章从Feign 远程调用的重要组件开始,图文并茂的介绍 Feigh 远程调用的执行流程、Feign 本地 JDK Proxy 实例的创建流程,彻底的为大家解读 SpringCl...
