SpringCloud OpenFeign报错

No Feign Client for loadBalancing defined. Did you forget to include spring-cloud-starter-loadbalancer?

问题原因

使用Spring Initializr初始化项目引入了openfeign,没有在意版本。直到运行项目进行远程调用时报错.

由于Spring Cloud Feign在Hoxton.M2 RELEASED版本之后不再使用Ribbon而是使用spring-cloud-loadbalancer,所以不引入spring-cloud-loadbalancer会报错.

解决方法:

加入spring-cloud-loadbalancer依赖 并且在nacos中排除ribbon依赖,不然loadbalancer无效

  • 排除ribbon依赖
<dependency>
   <groupId>com.alibaba.cloud</groupId>
    <artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>
    <exclusions>
        <exclusion>
            <groupId>com.netflix.ribbon</groupId>
            <artifactId>ribbon</artifactId>
        </exclusion>
    </exclusions>
</dependency>
  • 添加依赖
<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-loadbalancer</artifactId>
</dependency>

如果还是没有解决,请去官方查阅框架对应的版本,实在不行将spring boot和spring cloud的版本全部降下来。
