解决方案：

maven引入依赖错误。

<dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-netflix-eureka-client</artifactId>
        </dependency>

替换为

<dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
        </dependency>

1、spring-cloud-starter-loadbalancer依赖是否正确配置；2、yml或properties文件是否添加。检查完成可以尝试查看问题是否解决了。

3、一般定义feign接口的模块都是没有启动类的模块，若想要在其他模块调用此模块中的feign接口，是否在Resource/META-INF/spring.factories中手动配置了feign接口的实现类。要么就是报错的bean上面没有加注解，比如@Service、@Component、@Mapper、@Repository、@Configuration、@RestController等。2、feign接口实现类上方是否加了@Service注解。1、feign接口是否定义了实现类，最好添加实现类。

已解决：org.springframework.cloud.client.discovery.EnableDiscoveryClient 不存在

PS:为什么清除缓存有用，我认为是这种的，创建项目索引，大型项目在创建索引的过程中可能会出现依赖没有正常加载的问题！并且，IDEA 的缓存和索引主要是用来加快文件查询的速度，但是如果你的缓存和索引在新加入依赖后没有更新或者这部分内容没有正常加载，这时候你启动项目就会出现第二种原因，依赖是正常的，但是就是报错！针对我遇到的导致问题的第二种原因，经过测试有两种解决问题的方式！将项目交给maven管理，但是有可能会导致其他的问题！错误，这个错误蛮奇怪的，有必要记录一下。在IDEA中，清空缓存。
