java - Dubbo服务启动错误:Error creating bean with name 'userServiceImpl' nested exception is org. I0Itec.zkclient.exception.ZkTimeoutException

Question

我配置了dubbo，使用注册表zookeeper，启动服务时出现错误。

1. 我将超时修改为 10000，但错误没有改变。
2. 我关闭了虚拟机中的防火墙，错误没有改变。
3. 我检查了dubbo和zookeeper，它们都在运行。

###This is the code I configured for the dubbo service.###

<dubbo:application name="pinyougou-user-service" />
<dubbo:registry address="zookeeper://192.168.25.128:2181" />
<dubbo:annotation package="com.pinyougou.user.service.impl" />

###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.

Answer 1

错误是因为zookeeper连接异常:

1. 检查您的注册地址(IP、端口)
2. 检查 zk-client 和 zk-server 版本。
