第一步：配置文件允许覆盖Bean
spring: main: allow-bean-definition-overriding: true第二步：配置Bean
package com.ciih.refine.config; import okhttp3.*; import org.springframework.cloud.commons.httpclient.DefaultOkHttpClientFactory; import org.springframework.cloud.commons.httpclient.OkHttpClientFactory; import org.springframework.cloud.openfeign.EnableFeignClients; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import java.io.IOException; import java.net.InetSocketAddress; import java.net.Proxy; @Configuration //配置openfein接口的文件件路径 @EnableFeignClients(basePackages = "com.ciih.refine.server") public class Config { @Bean public OkHttpClientFactory okHttpClientFactory(OkHttpClient.Builder builder) { return new ProxyOkHttpClientFactory(builder); } static class ProxyOkHttpClientFactory extends DefaultOkHttpClientFactory { public ProxyOkHttpClientFactory(OkHttpClient.Builder builder) { super(builder); //配置IP、端口 Proxy proxy = new Proxy(Proxy.Type.HTTP, new InetSocketAddress("190.168.1.1", 8080)); builder.proxy(proxy); builder.proxyAuthenticator(new Authenticator() { @Override public Request authenticate(Route route, Response response) throws IOException { //设置代理服务器账号密码 String credential = Credentials.basic("admin", "admin"); return response.request().newBuilder() .header("Proxy-Authorization", credential) .build(); } }); //如果要配置限制域则加上下面 /*List
