　　maven工程分模块项目可以模块与模块之间的耦合度降低，各模块之间的联系就没有那么的紧密。通常情况下为了打包方便，建立一个父类的模块。这样打包发布的时候就不用一个个模块打包过去，只有父类的模块手动打包下就可以了，

工程如下图所示：

其中book-parent为父类模块，book-core持久层，book-service为服务层，book-web的可视化层，既分别对应mvc中的相应层。

一、book-core

1、添加包支持，pom.xml配置如下：


     	
      
       4.0.0
      	
      
       book-core
      	
      
       jar
      	
      		
       
        com.myWebApp
       		
       
        book-parent
       		
       
        0.0.1-SNAPSHOT
       		
       
        ../book-parent/pom.xml
       	
      	
      
       book-core
      
      	
      		
       
        UTF-8
       	
      	
      		
       			
        
         org.hibernate
        			
        
         hibernate-core

              jar-no-fork

　　注意：有些包是多余的，

2、实体类User代码如下：

package com.mr.cheng.entity;public class User {    private Integer id;    private String descn;    private String username;    private String password;    public Integer getId() {        return id;    }    public void setId(Integer id) {        this.id = id;    }    public String getDescn() {        return descn;    }    public void setDescn(String descn) {        this.descn = descn == null ? null : descn.trim();    }    public String getUsername() {        return username;    }    public void setUsername(String username) {        this.username = username == null ? null : username.trim();    }    public String getPassword() {        return password;    }    public void setPassword(String password) {        this.password = password == null ? null : password.trim();    }}

3、User实体类对已的Dao与xml文件代码如下：


     
       
          
           
           
           
         
        
      
           delete from users    where Id = #{id,jdbcType=INTEGER}  
        
      
           insert into users (Id, descn, username,       password)    values (#{id,jdbcType=INTEGER}, #{descn,jdbcType=VARCHAR}, #{username,jdbcType=VARCHAR},       #{password,jdbcType=VARCHAR})  
        
      
           update users    set descn = #{descn,jdbcType=VARCHAR},      username = #{username,jdbcType=VARCHAR},      password = #{password,jdbcType=VARCHAR}    where Id = #{id,jdbcType=INTEGER}

package com.mr.cheng.dao;import com.mr.cheng.entity.User;import java.util.List;import org.springframework.stereotype.Component;/** * 注意注解@Component必须有，也可以用Service或者Controller代替 * @author zwc * */@Componentpublic interface IUserDao {    int deleteByPrimaryKey(Integer id);    int insert(User record);    User selectByPrimaryKey(Integer id);    List
     
       selectAll();    int updateByPrimaryKey(User user);}

4、spring-mybatis.xml配置如下：

5、测试类如下：

package com.mr.cheng.test;import org.junit.runner.RunWith;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.test.context.ContextConfiguration;import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;import com.mr.cheng.dao.IUserDao;import com.mr.cheng.entity.User;public class MyAppTest {	@Autowired	private IUserDao iUserDao;		public void addUserTest(){		User user = new User();		user.setDescn("111");		user.setPassword("password");		user.setUsername("cheng");		iUserDao.insert(user);	}}

二、book-service

1、book-service是服务层，它对外提供接口。控制层不需要知道具体的实现，只有根据相应的接口就可以去选择他要想的服务。

接口代码如下：

package com.mr.cheng.biz;import java.util.List;import org.springframework.stereotype.Component;import com.mr.cheng.entity.User;@Componentpublic interface UserBizDao {    int deleteByPrimaryKey(Integer id);    int insert(User record);    User selectByPrimaryKey(Integer id);    List
      
        selectAll();    int updateByPrimaryKey(User user);}

View Code

实现类：

package com.mr.cheng.biz.impl;import java.util.List;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Service;import com.mr.cheng.biz.UserBizDao;import com.mr.cheng.dao.IUserDao;import com.mr.cheng.entity.User;@Servicepublic class UserBizDaoImpl implements UserBizDao {    @Autowired    private IUserDao iUserDao;    public int deleteByPrimaryKey(Integer id) {        iUserDao.deleteByPrimaryKey(id);        return 0;    }    public int insert(User record) {        iUserDao.insert(record);        return 0;    }    public User selectByPrimaryKey(Integer id) {        return iUserDao.selectByPrimaryKey(id);    }    public List
      
        selectAll() {        return iUserDao.selectAll();    }    public int updateByPrimaryKey(User user) {        iUserDao.updateByPrimaryKey(user);        return 0;    }}

View Code

2、配置文件：

spring-service如下：

View Code

pom.xml代码如下：


        
       
        4.0.0

三、book-web模块

1、book-web是web项目，在这个模块项目中他有页面以及相应的控制层组成。页面既是mvc中的视图，同事也包含了mvc中的控制层。

控制层代码：

package com.mr.cheng.controller;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.RequestMethod;import com.mr.cheng.biz.UserBizDao;import com.mr.cheng.entity.User;@Controller@RequestMapping("/userController.do")public class UserController {    @Autowired    private UserBizDao userBizDao;    @RequestMapping("/login")    public String login(){        User user = new User();        user.setDescn("1111");        user.setUsername("abc");        user.setPassword("pass");        userBizDao.insert(user);        return "success";    }}
