Dubbo项目搭建

来源：互联网发布：阿里办公软件编辑：程序博客网时间：2024/06/05 19:07

本节我们演示下dubbo项目的搭建，服务端和客户端进行远程通信，通过zookeeper进行注册的实现。

项目结构图

Dubbo-client客户端

Dubbo-host 宿主服务

Dubbo-model实体Model

Dubbo-service服务

Dubbo-service-impl服务实现

项目分为5个模块，客户端使用的时候只需把接口Dubbo-service和Dubbo-model给客户端，进行远程调用

model

model层需要实现序列化接口Serializable

package com.dubbo.model;import java.io.Serializable;public class ProductModel implements Serializable {//产品名称private String name;//产品编码private String code;public String getName() {return name;}public void setName(String name) {this.name = name;}public String getCode() {return code;}public void setCode(String code) {this.code = code;}}

dubbo-service

package com.dubbo.service;import java.util.List;import com.dubbo.model.ProductModel;public interface ProductService {public  List<ProductModel> GetAllProcuct();}

dubbo-service-impl

package com.dubbo.service.impl;import java.util.ArrayList;import java.util.List;import com.dubbo.model.ProductModel;import com.dubbo.service.ProductService;public class ProductServiceImpl implements ProductService  {public List<ProductModel> GetAllProcuct() {// TODO Auto-generated method stubList<ProductModel> list=new ArrayList<ProductModel>();ProductModel  model1=new ProductModel();model1.setCode("001");model1.setName("可口可乐");list.add(model1);ProductModel  model2=new ProductModel();model2.setCode("002");model2.setName("百事可乐");list.add(model2);ProductModel  model3=new ProductModel();model3.setCode("003");model3.setName("非常可乐");list.add(model3);return list;}}

宿主host

package com.dubbo.host;import java.io.IOException;import org.springframework.context.ApplicationContext;import org.springframework.context.support.ClassPathXmlApplicationContext;/** * Hello world! * */public class App {    public static void main( String[] args )    {        ClassPathXmlApplicationContext  context =new ClassPathXmlApplicationContext(new String[] {"applicationContext.xml"});          context.start();          System.out.println( "dubbol服务启动" );        try {System.in.read();} catch (IOException e) {// TODO Auto-generated catch blocke.printStackTrace();}        System.out.println("关闭服务");        context.close();    }}
