springcloud 运行时报熔断器相关错误

问题:

springcloud的项目用maven启动时爆出异常，求解。一直提醒找不到org.springframework.cloud.client.circuitbreaker.CircuitBreakerFactory。
在pom里已经添加了相关引用：
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-openfeign</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-netflix-hystrix</artifactId>
</dependency>
错误信息：

回答1:

@EnableHystrixDashboard 这个除掉；

@EnableFeignClients 包含rebbion 和 hystrix

 

或者换依赖 ：
