dubbo+zookeeper+jsp+springmvc+spring+mybatis+mysql+maven完整示例

项目分为三部分，这里分为三个maven项目(基于web，所以最后一个为maven创建的web项目)

1.接口定义以及实体类定义（api+pojo） --- maven创建java项目，打包成jar

2.dubbo的服务提供方：定义接口实现，底层使用mybatis持久层框架，mysql数据库 在这里配置mapper文件以及dubbo-provider的配置文件，还有spring和mybatis整合的文件 ---maven创建java项目，打包成jar

3.dubbo的服务消费方：定义controller类，Jsp页面，配置springmvc的配置文件，web.xml文件，dubbo-consumer的配置文件 ---maven创建的web项目，打包成war包

4.zookeeper：dubbo的注册中心（自己下载 ，找到bin目录下的zkServer.cmd双击打开 ）找不到下载地址的可以从我的github上面下载 ，这是我的整个项目链接，第四个zookeeper.zip就是zookeeper的包 需要项目源码的也可以直接下载  https://github.com/DFX339/dubbo_zookeeper_SSM.git

（1）**********************************数据库（MYSQL）***************************************

创建数据库dubbo ：  create dababase dubbo

在dubbo数据库中创建user表,字段如下：

（2）***********************************接口设计（maven创建的java项目 打包成jar）************************************

Eclipse使用maven工具创建java项目，项目结构如下

接口maven项目的pom.xml配置如下

持久层接口 UserMapper.java设计如下

package com.dfx.dubbo.demo_provider.mapper;

import org.mybatis.spring.annotation.MapperScan;

import com.dfx.dubbo.demo_interface.pojo.User;

@MapperScan
public interface UserMapper {

    public void add(User user);
    
    public void edit(User user);
    
    public User findById(int id);
    
    public void delete(int id);
}

持久层接口的Mapper配置文件UserMapper.xml如下

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">

        <result column="username" property="username" />
        <result column="password" property="password" />
        <result column="age" property="age" />
    </resultMap>
     -->

    <!-- 新增操作 -->
    <insert id="add" parameterType="com.dfx.dubbo.demo_interface.pojo.User" >
        insert into user(username,password,age) values(#{username},#{password},#{age})
    </insert>

    <!-- 修改操作 -->
    <update id="edit" parameterType="com.dfx.dubbo.demo_interface.pojo.User">
        update user set username=#{username},password=#{password},age=#{age} where id=#{id}
    </update>
    
    <!-- 删除操作 -->
    <delete id="delete" parameterType="int">
        delete  from user where id=#{0}
    </delete>
    
    <!-- 查询操作 -->
    <select id="findById" parameterType="int" resultType="com.dfx.dubbo.demo_interface.pojo.User">
        select id,username,password,age from user where id=#{0}
    </select>
    
    </mapper>

业务实现类UserService.java如下

package com.dfx.dubbo.demo_provider.service.impl;

import javax.annotation.Resource;

import com.dfx.dubbo.demo_interface.api.UserIService;
import com.dfx.dubbo.demo_interface.pojo.User;
import com.dfx.dubbo.demo_provider.mapper.UserMapper;

/**
 * 业务层接口方法实现类
 * @author Administrator
 *
 */
public class UserService implements UserIService {

    @Resource
    private UserMapper userDao;
    
    @Override
    public void add(User user) {
        userDao.add(user);
    }

    @Override
    public void edit(User user) {
        userDao.edit(user);
    }

    @Override
    public User findById(int id) {
        return userDao.findById(id);
    }

    @Override
    public void delete(int id) {
        userDao.delete(id);
    }

}

服务提供者开启服务的主类 Provider.java如下

package com.dfx.dubbo.demo_provider.main;

import java.io.IOException;

import org.springframework.context.support.ClassPathXmlApplicationContext;

/**
 * 
 * 开启服务主类
 * 
 * */
public class Provider {
    static int count=0;
    public static void main(String[] args) throws IOException{
        count++;
        System.out.println("123开始，count="+count+"，执行了--"+count+"次");
        ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext(new String[]{"applicationContex_provider.xml"});
        context.start();
        System.in.read();
        
    }
}

mybatis的配置文件mybatis-config.xml

到这里了就可以下载zookeeper，然后打开文件夹，进入bin目录，双击zkServer.cmd 启动 （让它一直处于启动状态，可以放置一边了）

先将接口项目 demo-interface打包成jar包(打包方式：Eclipse工具 右击项目 maven install)

再将服务提供方项目 demo_provider打包为jar包（打包方式：Eclipse工具 右击项目 maven install)

找到demo_provider项目的Provider.java，以Java Applicaion的方式执行 执行结果如下

看到这里，说明前面的配置都没问题

配置结束，接下来就是部署项目到Tomcat上了

先将项目打包为war,  Eclipse开发工具 右击项目 run as  --> maven install

运行项目： 右击项目--》run as -->Run on Server (执行成功的前提： zkServer.cmd处于打开状态，Provider.java处于运行状态，demo_interface,demo_provider两个项目都已经使用maven命令打包为jar)

运行项目的结果

点击超链接 查询 的结果（其余增加、修改、删除都是一样 ）
