Dubbo调用建model

SSM+dubbo+zookeeper搭建分布式框架

好的，废话不多说，直接开始搭。

这个项目总工分为四个部分：
dubbo-parent

dubbo-server

dubbo-service-api

dubbo-client

至于其他的你还想在细分的，只要学会这个以后，都是可以的。

准备工作

安装zookeeper并启动

eclipse配置dubbo.xsd，不然在配置文件中没法用dubbo

ssm框架

dubbo-parent搭建

这个项目整个是基于ssm基础的，所以应该至少会SSM框架的搭建（相信大家都会哦）

开始搭建：

1.新建一个maven项目，选择maven project

2.注意标注的地方，一定要打勾

3. 记得选择packaging类型为pom

4.打开该项目的pom.xml文件，导入依赖：

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

	<version>0.0.1-SNAPSHOT</version>
	<packaging>pom</packaging>

注意待会添加完子项目后，pom.xml会自动添加如下配置

<modules>
	<module>dubbo-server</module>
	<module>dubbo-client</module>
</modules>

dubbo-parent搭建完成

dubbo-service-api的搭建

新建一个maven项目，项目名叫dubbo-service-api

单击左上角file->new->orther->maven->maven project

注意这里要打勾哦

2.选择 quickstart项目

点击finish，完成创建

然后在此项目中添加两个类：User.实体类和UserService接口

package com.dubbo.entity;

import java.io.Serializable;
import java.util.Date;

/**
 * 用户实体类
 * @author 郭鹏飞
 *
 */
public class User implements Serializable{
	
	private String id;
	private String name;
	private String password;
	private String salt;
	private Date createTime;
	private Date updateTime;
	private int b_enable;
	
	public String getId() {
		return id;
	}
	public void setId(String id) {
		this.id = id;
	}
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	public String getPassword() {
		return password;
	}
	public void setPassword(String password) {
		this.password = password;
	}
	public String getSalt() {
		return salt;
	}
	public void setSalt(String salt) {
		this.salt = salt;
	}
	public Date getCreateTime() {
		return createTime;
	}
	public void setCreateTime(Date createTime) {
		this.createTime = createTime;
	}
	public Date getUpdateTime() {
		return updateTime;
	}
	public void setUpdateTime(Date updateTime) {
		this.updateTime = updateTime;
	}
	public int getB_enable() {
		return b_enable;
	}
	public void setB_enable(int b_enable) {
		this.b_enable = b_enable;
	}
}

package com.dubbo.service;

import java.util.List;

import com.dubbo.entity.User;

/**
 * 用户操作实现类
 * @author 郭鹏飞
 *
 */
public interface UserService {

	List<User> getAllUser();
	
}

dubbo-service-api项目创建完毕

<dependency>
			<groupId>com.test.dubbo</groupId>
			<artifactId>dubbo-service-api</artifactId>
			<version>0.0.1-SNAPSHOT</version>
		</dependency>

dubbo-server搭建

右键dubbo-parent项目，新建一个maven module项目

新建完成，添加SSM框架的一些配置文件

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"
	xmlns:dubbo="http://code.alibabatech.com/schema/dubbo"
	xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd  
    http://code.alibabatech.com/schema/dubbo  
    http://code.alibabatech.com/schema/dubbo/dubbo.xsd">

	<!-- 提供方应用信息，用于计算依赖关系 -->
	<dubbo:application name="test_provider" />

	<!-- 使用zookeeper注册中心暴露服务地址 -->
	<dubbo:registry address="zookeeper://127.0.0.1:2181" />

	<!-- 用dubbo协议在20880端口暴露服务 -->
	<dubbo:protocol name="dubbo" port="20880" />
	<!-- 声明需要暴露的服务接口 -->
	<dubbo:service interface="com.dubbo.service.UserService"
		ref="userService" />
	<!-- 具体的实现bean -->
	<bean id="userService" class="com.test.dubbo.service.impl.UserServiceImpl" />
	<dubbo:service interface="com.dubbo.service.RedisService"
		ref="redisService" />
	<bean id="redisService" class="com.test.dubbo.service.impl.RedisServiceImpl" />
</beans>

dubbo-client框架搭建

新建一个dubbo-client项目，创建方法跟dubbo-server一样

同时为该框架搭建一个SSM环境

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"
	xmlns:dubbo="http://code.alibabatech.com/schema/dubbo"
	xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd  
    http://code.alibabatech.com/schema/dubbo  
    http://code.alibabatech.com/schema/dubbo/dubbo.xsd">

	<!-- 提供方应用信息，用于计算依赖关系 -->
	<dubbo:application name="test_consumer" />

	<!-- 使用zookeeper注册中心暴露服务地址 -->
	<dubbo:registry address="zookeeper://127.0.0.1:2181" />

	<!-- 用dubbo协议在20880端口暴露服务 -->
	<dubbo:protocol name="dubbo" port="20880" />
	<!-- 声明需要暴露的服务接口 -->
	<dubbo:reference interface="com.dubbo.service.UserService"
		id="userService" check="false" />
	<dubbo:reference interface="com.dubbo.service.RedisService"
		id="redisService" check="false" />
</beans>

新建一个UserController类

package com.dubbo.controller;

import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

import com.alibaba.fastjson.JSONArray;
import com.dubbo.entity.User;
import com.dubbo.service.RedisService;
import com.dubbo.service.UserService;

@Controller
@RequestMapping("/test")
public class TestController {

	@Autowired
	private UserService userService;
	@Autowired
	private RedisService redisService;
	private SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
	
	@RequestMapping("/getUser")
	@ResponseBody
	public String getUser(){
		System.out.println(sdf.format(new Date())+"==========================================开始=======================================");
		List<User> list = userService.getAllUser();
		String json = JSONArray.toJSON(list).toString();
		System.out.println(sdf.format(new Date())+"==========================================结束=======================================");
		return json;
	}
}

测试

运行zookeeper服务器

将dubbo-server项目和dubbo-client项目拉进两个Tomcat里（一个也可以），运行两个项目

在页面中访问localhost:8080/dubbo-client/test/getUser.html

返回数据库中的数据，测试成功
