feign调用失败 feign.RetryableException: xxx-service executing GET http://xxx/test

寂夜了无痕2023-09-05 16:01

一。 问题引入

升级springcloud的版本后 突然发现 以前正常的feign调用也报错了

升级后的各组件版本如下

spring cloud 2021.0.5

spring cloud alibaba 2021.0.5.0

spring boot 2.6.13

错误日志如下

二。问题分析

刚看到 Caused by: java.net.UnknownHostException: xxx-service

还以为网络问题，居然一想 这是feign调用

然后开始逐步排查

  • 检查调用的服务 是否在nacos上
  • 检查 调用者 与调用者是否在同一个 namespace上
  • 检查被调用的服务启动状况
    检查完成 也没发现问题
    问题的本质还是 服务间调用不同 然后开始从官网找下文档 文档的

官方文档的描述如下 https://docs.spring.io/spring-cloud-openfeign/docs/3.1.8/reference/html/#netflix-feign-starter

spring-cloud-starter-openfeign supports spring-cloud-starter-loadbalancer. However, as is an optional dependency, you need to make sure it been added to your project if you want to use it.

openfeign 默认的负载均衡组件是ribbon 由于我们升级了springcloud版本 新版本的springcloud 移除了ribbon 所以为了openfeign 负载均衡生效 我们需要引入loadbalancer

三。问题解决

  • 引入loadbalancer
xml 复制代码 
<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-loadbalancer</artifactId>
</dependency>

四。 另外说明

feign调用失败的异常 还有其他的原因 如上只是一种可能 包括但不仅限于如下

  • 被调用方未注册到nacos 或者注册nacos失败
  • 被调用方和调用方 不在同一个 namespace
  • 被调用方和调用方 不在同一个 nacos
  • 被调用方 应用未启动
  • 被调用方 调用失败报错
  • feign client设置问题 name不对
  • feign client设置问题 url 有误
  • 网络问题超时
  • 框架版本兼容问题
  • 等等
