一、安装zookeeper

docker pull zookeeper

　　

二、dubbo-provider

　　2.2 配置

server.port=9999
spring.dubbo.application.name=dubbo_provider
spring.dubbo.registry.protocol=zookeeper
spring.dubbo.registry.address=zookeeper://172.19.82.243:32777
spring.dubbo.protocol.name=dubbo
spring.dubbo.protocol.port=20880
spring.dubbo.server=true
spring.dubbo.scan.base-packages=com.cnblogs.pengsn.dubbo.provider.service

       2.3 接口实现

package com.cnblogs.pengsn.dubbo.provider.service.impl;

import java.util.UUID;

import org.springframework.stereotype.Component;

import com.alibaba.dubbo.config.annotation.Service;
import com.cnblogs.pengsn.dubbo.provider.pojo.UserInfo;
import com.cnblogs.pengsn.dubbo.provider.service.ITestService;

@Component
@Service(version = "1.0" , interfaceClass = ITestService.class)
public class TestServiceImpl implements ITestService{

    public UserInfo queryUserInfo(UserInfo userInfo) {
        System.err.println(userInfo.toString());
        UserInfo ui = new UserInfo();
        ui.setUserId(UUID.randomUUID().toString());
        ui.setUserName("pengsn");
        return ui;
    }

}

package com.cnblogs.pengsn.dubbo.provider.service;

import com.cnblogs.pengsn.dubbo.provider.pojo.UserInfo;

public interface ITestService {

    public UserInfo queryUserInfo( UserInfo userInfo );
    
}

package com.cnblogs.pengsn.dubbo.provider.pojo;

import java.io.Serializable;

public class UserInfo implements Serializable {

    /**
     * 
     */
    private static final long serialVersionUID = 2391763259872013964L;

    private String userName;
    
    private String userId;

    public String getUserName() {
        return userName;
    }

    public void setUserName(String userName) {
        this.userName = userName;
    }

    public String getUserId() {

    }
    
    @Override
    public String toString() {
        return "userName: " + userName + "; userId: " + userId;
    }
    

}

       2.4 服务启动　　

package com.cnblogs.pengsn;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

import com.alibaba.dubbo.config.spring.context.annotation.EnableDubbo;

@SpringBootApplication
@EnableDubbo
public class DubboServerApplication {

    public static void main(String[]args) {
        SpringApplication.run(DubboServerApplication.class, args);
    }
    
}
