IllegalStateException: No Feign Client for loadBalancing defined.

IllegalStateException: No Feign Client for loadBalancing defined. 这个异常是由于没有定义Feign Client来进行负载均衡导致的。解决这个问题的方法是引入spring-cloud-starter-loadbalancer依赖。在Hoxton.M2 RELEASED版本之后，Spring Cloud Feign已经不再使用Ribbon，而是改用spring-cloud-loadbalancer。所以需要确保在项目中引入了spring-cloud-loadbalancer的依赖。

This error message indicates that there is no Feign client defined for load balancing and suggests that you may have forgotten to include the `spring-cloud-starter-loadbalancer` dependency.

To resolve this issue, you can add the following dependency to your project's `pom.xml` file:

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-loadbalancer</artifactId>
</dependency>

This will provide your Feign client with the necessary load balancing functionality from Spring Cloud LoadBalancer.

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

这个错误通常是因为你在使用 Feign 客户端进行负载均衡时，忘记在项目中引入 `spring-cloud-starter-loadbalancer` 依赖导致的。`spring-cloud-starter-loadbalancer` 是 Spring Cloud 中用于客户端负载均衡的模块，如果没有引入该依赖，Feign 就无法使用负载均衡功能。

你可以在项目的 pom.xml 文件中添加以下依赖：

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-loadbalancer</artifactId>
</dependency>

添加完依赖后，重新编译运行项目即可。
