@EnableFeignClients(defaultConfiguration= FeignClientConfiguration.class) ② 如果是局部配置,则把它放到@FeignClient这个注解中 @FeignClient(value= "userservice", configuration = FeignClientConfiguration.class) 总结: Feign的日志配置: 方式一是配置文件,feign.client.config.xxx.loggerLevel 如果xxx是default则代表...

1.方案一: 需要在@Configuration注解修饰的类中进行证书认证忽略的操作,这样就可以访问https开头的url pom.xml 配置 此时使用SpringClou...

一、Feign介绍 1. 什么是Feign? Feign是Netfix开源的声明式HTTP客户端 Github地址:https://github.com/openfeign/feign 2. Feign组件: 二、基于Feign实现微服务远程调用 2.1. 引入feign依赖 <dependency> <groupId>org.springframework.cloud</groupId>
@FeignClient(name = "dynamic") interface DynamicClient { @GetMapping("/") String get(URI uri); } dynamicClient.get(URI.create("https://github.com")); 1. 2. 3. 4. 5. 6. 7. 执行后会抛出负载均衡的异常: java.lang.RuntimeException: com.netflix.client.ClientException: ...
https://github.com/OpenFeign/feign/blob/master/core/src/main/java/feign/Retryer.java PHASE 8. 发送Http请求 Feign 真正发送HTTP请求是委托给 feign.Client 来做的: Feign 默认底层通过JDK 的 java.net.HttpURLConnection 实现了feign.Client接口类,在每次发送请求的时候,都会创建新的HttpURLConnection 链接,...
@FeignClient(name="dynamic")interfaceDynamicClient{@GetMapping("/")Stringget(URIuri);}dynamicClient.get(URI.create("https://github.com")); 执行后会抛出负载均衡的异常: java.lang.RuntimeException: com.netflix.client.ClientException: Load balancer does not have available server for client: github...
@EnableFeignClients public class FeignApplication { public static void main(String[] args) { SpringApplication.run(FeignApplication.class, args); } } 3.接口定义:我们这里调用USER-SERVICE服务,在该服务中创建一个查询所有用户的接口,然后在feign-consumer中定义。
