No Feign Client for loadBalancing defined.Feign报错的解决办法
No Feign Client for loadBalancing defined. Did you forget to include spring-cloud-starter-loadbalancer?
这是一个版本不兼容问题
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.
所以需要去掉ribben，添加loadbalancer
修改nacos的依赖
<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>
然后再有spring-cloud的模块里添加loadbalancer
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-loadbalancer</artifactId>
</dependency>
