Dubbox常见错误

一、在注册中心找不到对应的服务

java.lang.IllegalStateException: Failed to check the status of the service com.pinyougou.sellergoods.service.BrandService. No provider available for the service com.pinyougou.sellergoods.service.BrandService from the url zookeeper://192.168.25.129:2181/com.alibaba.dubbo.registry.RegistryService?application=pinyougou-manager-web&dubbo=2.8.4&interface=com.pinyougou.sellergoods.service.BrandService&methods=update,get,delete,selectOptionList,add,getListByPage&pid=3980&revision=0.0.1-SNAPSHOT&side=consumer×tamp=1501146823396 to the consumer 172.16.17.14 use dubbo version 2.8.4

这种错误是服务层代码没有成功注册到注册中心导致，请检查一下你的服务层代码是否添加了@service注解，并且该注解的包一定是com.alibaba.dubbo.config.annotation包，不是org.springframework.stereotype.Service，这个地方极容易出错。另外还有一个原因就是你的服务层工程由于某些原因没有正常启动，也无法注册到注册中心里。

 

 

二、无法连接到注册中心

org.I0Itec.zkclient.exception.ZkTimeoutException: Unable to connect to zookeeper server within timeout: 5000         org.I0Itec.zkclient.ZkClient.connect(ZkClient.java:876) org.I0Itec.zkclient.ZkClient.(ZkClient.java:98)         org.I0Itec.zkclient.ZkClient.(ZkClient.java:92)        org.I0Itec.zkclient.ZkClient.(ZkClient.java:80)          com.alibaba.dubbo.remoting.zookeeper.zkclient.ZkclientZookeeperClient.(ZkclientZookeeperClient.java:26)

请检查IP与端口是否填写正确，检查注册中心是否正常启动
