所有功能开发完后，启动course-edge-service时报错：
java.lang.IllegalStateException: Failed to check the status of the service com.imooc.course.service.ICourseService. No provider available for the service com.imooc.course.service.ICourseService from the url zookeeper://127.0.0.1:2181/com.alibaba.dubbo.registry.RegistryService?application=course-service&dubbo=2.5.3&interface=com.imooc.course.service.ICourseService&methods=CourseList&pid=2168&side=consumer&timestamp=1547048713151 to the consumer 172.22.152.129 use dubbo version 2.5.3

我查看了zookeeper的控制台输出：
2019-01-09 23:45:13,502 [myid:] - INFO [ProcessThread(sid:0 cport:2181)::PrepRequestProcessor@653] - Got user-level KeeperException when processing sessionid:0x10000418de40000 type:create cxid:0x10 zxid:0xd txntype:-1 reqpath:n/a Error Path:/dubbo/com.imooc.course.service.ICourseService Error:KeeperErrorCode = NodeExists for /dubbo/com.imooc.course.service.ICourseService

想问一下老师这是什么原因造成的？具体应该怎么修改？
