spring boot + dubbo 服务部署实例

项目github：https://github.com/nalidou/spring-dubbo

1. 公共组件：dubbo-component

提供了接口定义、实体类等，其他项目可以直接导入jar包，也可以用maven导入。

    4.0.0
    com.wzy
    dubbo-component
    1.0

2. 服务生产者：dubbo-producer

实现了公共组件接口

        
            com.alibaba.spring.boot
            dubbo-spring-boot-starter
            2.0.0
        

        
            org.springframework.boot
            spring-boot-starter-test
            test
        
        
            org.apache.zookeeper
            zookeeper
            3.4.6
        
        
        
            com.101tec
            zkclient
            0.10
        

        
            com.wzy
            dubbo-component
            1.0
        
    

package com.wzy.dubbo.producer.server;

import com.alibaba.dubbo.config.annotation.Service;
import com.wzy.component.entity.User;
import com.wzy.component.server.IUserServer;
import org.springframework.stereotype.Component;

import java.util.ArrayList;
import java.util.List;
@Service(interfaceClass = IUserServer.class) //这里用的是dubbo的接口
@Component
public class UserServerImpl implements IUserServer {
    @Override
    public User getById(long id) {
        return new User(id, "小明");
    }

    @Override
    public List getAll() {
        List list = new ArrayList();
        list.add(new User(100, "jerry"));
        list.add(new User(200, "tom"));
        return list;
    }
}

 3. web服务（服务消费者）：dubbo-web

        
            org.springframework.boot
            spring-boot-starter-web
        
        
            com.alibaba.spring.boot
            dubbo-spring-boot-starter
            2.0.0
        

        
            org.springframework.boot
            spring-boot-starter-test
            test
        
        
            org.apache.zookeeper
            zookeeper
            3.4.6
        
        
        
            com.101tec
            zkclient
            0.10
        

        
            com.wzy
            dubbo-component
            1.0
        
    

package com.wzy.dubbo.web;

import com.alibaba.dubbo.config.annotation.Reference;
import com.wzy.component.entity.User;
import com.wzy.component.server.IOrderServer;
import com.wzy.component.server.IUserServer;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class WebCtl {
    @Reference
    private IOrderServer orderServer;
    @Reference
    private IUserServer userServer;

    @RequestMapping("getUser")
    public User getUser() {
        System.out.println("WebCtl getUser...");
        System.out.println(orderServer.getName());
        return userServer.getById(100);
    }
}

4. 在zookeeper上查看注册节点
