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

报错内容

Unexpected exception during bean creation; nested exception is java.lang.IllegalStateException: No Feign Client for loadBalancing defined. Did you forget to include spring-cloud-starter-loadbalancer?

原因

出现这个问题是没有loadbalanc 但是nacos中ribbon会造成loadbalanc包失效

解决方式

在pom文件中引入以下依赖

<dependency>
    <groupId>com.alibaba.cloud</groupId>
    <artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>

            <artifactId>spring-cloud-starter-netflix-ribbon</artifactId>
