Dubbo服务启动错误：创建名为'；userServiceImpl'；嵌套异常为org.I0Itec.zkclient.exception.ZkTimeoutException 我使用注册表zookeeper配置了dubbo，当我启动服务时，我得到一个错误。 我将超时修改为10000，错误没有改变 我关闭了虚拟机中的防火墙，错误没有改变 我检查了dubbo和动物园管理员，他们都在跑 错误内容 org.springframework.beans.factory.BeanCreationException:创建名为“userServiceImpl”的bean时出错[D:\Java\JavaCode\pinyougou\pinyougou itcast\pinyougou parent\pinyougou user service\target\classes\com\pinyougou\user\service\impl\userServiceImpl.class]：bean初始化失败；嵌套异常为org.I0Itec.zkclient.exception.ZkTimeoutException:无法在超时时间内连接到zookeeper服务器：5000 位于org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.doCreateBean（AbstractAutowireCapableBeanFactory.java:553） 位于org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.createBean（AbstractAutowireCapableBeanFactory.java:482） 位于org.springframework.beans.factory.support.AbstractBeanFactory$1.getObject（AbstractBeanFactory.java:306） 位于org.springframework.beans.factory.support.DefaultSingletonBeanRegistry.getSingleton（DefaultSingletonBeanRegistry.java:230） 位于org.springframework.beans.factory.support.AbstractBeanFactory.doGetBean（AbstractBeanFactory.java:302） 位于org.springframework.beans.factory.support.AbstractBeanFactory.getBean（AbstractBeanFactory.java:197） 位于org.springframework.beans.factory.support.DefaultListableBeanFactory.PreInstanceSingleton（DefaultListableBeanFactory.java:772） 位于org.springframework.context.support.AbstractApplicationContext.finishBeanFactoryInitialization（AbstractApplicationContext.java:839） 位于org.springframework.context.support.AbstractApplicationContext.refresh（AbstractApplicationContext.java:538） 位于org.springframework.web.context.ContextLoader.configureAndRefreshWebApplicationContext（ContextLoader.java:446） 位于org.springframework.web.context.ContextLoader.initWebApplicationContext（ContextLoader.java:328） 位于org.springframework.web.context.ContextLoaderListener.contextInitialized（ContextLoaderListener.java:107） 位于org.apache.catalina.core.StandardContext.listenerStart（StandardContext.java:4939） 位于org.apache.catalina.core.StandardContext.startInternal（StandardContext.java:5434） 位于org.apache.catalina.util.LifecycleBase.start（LifecycleBase.java:150） 位于org.apache.catalina.core.ContainerBase$StartChild.call（ContainerBase.java:1559） 位于org.apache.catalina.core.ContainerBase$StartChild.call（ContainerBase.java:1549） 位于java.util.concurrent.FutureTask.run（未知源） 位于java.util.concurrent.ThreadPoolExecutor.runWorker（未知源） 位于java.util.concurrent.ThreadPoolExecutor$Worker.run（未知源） 位于java.lang.Thread.run（未知源） 原因：org.I0Itec.zkclient.exception.ZkTimeoutException:无法在超时时间内连接到zookeeper服务器：5000 位于org.I0Itec.zkclient.zkclient.connect（zkclient.java:1223） 在org.I0Itec.zkclient.zkclient.（zkclient.java:155） 在org.I0Itec.zkclient.zkclient.（zkclient.java:129） 在org.I0Itec.zkclient.zkclient.（zkclient.java:125） 在org.I0Itec.zkclient.zkclient.（zkclient.java:92） 在com.alibaba.dubbo.remoting.zookeeper.zkclient.ZkclientZookeeperClient.（ZkclientZookeeperClient.java:26） 位于com.alibaba.dubbo.remoting.zookeeper.zkclient.ZkclientZookeeperTransporter.connect（ZkclientZookeeperTransporter.java:10） 访问com.alibaba.dubbo.remoting.zookeeper.ZookeeperTransporter$Adpative.connect（ZookeeperTransporter$Adpative.java） www.com.alibaba.dubbo.registry.zookeeper.ZookeeperRegistry.（ZookeeperRegistry.java:69） 位于com.alibaba.dubbo.registry.zookeeper.ZookeeperRegistryFactory.createRegistry（ZookeeperRegistryFactory.java:37） 位于com.alibaba.dubbo.registry.support.AbstractRegistryFactory.getRegistry（AbstractRegistryFactory.java:94） 登录com.alibaba.dubbo.registry.RegistryFactory$Adpative.getRegistry（RegistryFactory$Adpative.java） 位于com.alibaba.dubbo.registry.integration.RegistryProtocol.getRegistry（RegistryProtocol.java:190） 登录com.alibaba.dubbo.registry.integration.RegistryProtocol.export（RegistryProtocol.java:109） 访问com.alibaba.dubbo.rpc.ProtocolListenerWrapper.export（ProtocolListenerWrapper.java:54） 在com.alibaba.dubbo.rpc.protocolfilterRapper.export上（protocolfilterRapper.java:53） 位于com.alibaba.dubbo.rpc.Protocol$Adpative.export（Protocol$Adpative.java） 位于com.alibaba.dubbo.config.ServiceConfig.doexporturlsfor1协议（ServiceConfig.java:489） 在com.alibaba.dubbo.config.ServiceConfig.doexportURL（ServiceConfig.java:285）上 位于com.alibaba.dubbo.config.ServiceConfig.doExport（ServiceConfig.java:246） com.alibaba.dubbo.config.ServiceConfig.export（ServiceConfig.java:145） 在com.alibaba.dubbo.config.spring.AnnotationBean.postProcessAfterInitialization（AnnotationBean.java:202）上 位于org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.applyBeanPostProcessorsAfterInitialization（AbstractAutowireCapableBeanFactory.java:422） 位于org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.initializeBean（AbstractAutowireCapableBeanFactory.java:1583） 位于org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.doCreateBean（AbstractAutowireCapableBeanFactory.java:545） ... 20多

错误是因为zookeeper连接异常：

检查您的注册表地址（ip、端口）

检查zk客户端和zk服务器版本

---

应该是zookeeper连接问题，使用以下命令检查：

ping 192.168.25.128

如果zookeeper和dubbo服务在同一台机器上，您可以使用

localhost

###This is the configuration of the service###

package com.pinyougou.user.service.impl;
import com.alibaba.dubbo.config.annotation.Service;
@Service(interfaceName="com.pinyougou.user.service.UserService")
public class UserServiceImpl implements UserService {
...
}

###Zookeeper service starts normally###

JMX enabled by default
Using config: /root/zookeeper-3.4.6/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED

###The firewall is not turned on either.###
iptables: Firewall is not running.
