Idea SpringMVC+Spring+MyBatis+Maven整合

创建项目

File-New Project

选中左侧的Maven，选中右侧上方的Create from archetype，然后选中下方列表中的webapp，然后点击Next

在GroupId和ArtifactId中填入指定内容，点击Next

直接点Next

输入项目名称，Finish

Idea会自动开始下载所依赖的包，等待其完成。

项目结构

项目刚建好的时候是没有这些文件的，所以自己手动创建缺少的文件夹（包）

创建完后的项目框架：

修改pom.xml导入依赖包插件

依赖包需要如下：

spring framework
aspectj事务
c3p0数据源
servlet/jsp api
junit4
mybatis
mybatis spring整合
mysql driver

jstl

插件需要用到mybatis的逆向工程

完整的pom.xml代码清单：

使用mybatis逆向工程创建mapper接口和xml文件

user表结构

 DROP TABLE IF EXISTS `user`;
 /*!40101 SET @saved_cs_client     = @@character_set_client */;
 /*!40101 SET character_set_client = utf8 */;
 CREATE TABLE `user` (
   `id` int(11) NOT NULL AUTO_INCREMENT,
   `username` varchar(32) NOT NULL COMMENT '用户名称',
   `birthday` date DEFAULT NULL COMMENT '生日',
   `sex` char(1) DEFAULT NULL COMMENT '性别',
   `address` varchar(256) DEFAULT NULL COMMENT '地址',
   PRIMARY KEY (`id`)
 ) ENGINE=InnoDB AUTO_INCREMENT=27 DEFAULT CHARSET=utf8;

在main/resources中创建generatorConfig.xml文件

Service接口与实现

创建一个简单的service，只有一个查看所有用户列表的功能

UserService.java

 package com.elin4it.ssm.service;

 import com.elin4it.ssm.pojo.User;

 import java.util.List;

 /**
  * Created by 烽 on 2015/7/11.
  */
 public interface UserService {

     /**
      * 查找所有用户
      * @return
      * @throws Exception
      */
     List findUser()throws Exception;
 }

实现类UserServiceImpl.java

 package com.elin4it.ssm.service;

 import com.elin4it.ssm.mapper.UserMapper;
 import com.elin4it.ssm.pojo.User;
 import org.springframework.beans.factory.annotation.Autowired;
 import org.springframework.stereotype.Service;

 import java.util.List;

 /**
  * Created by 烽 on 2015/7/11.
  */
 @Service
 public class UserServiceImpl implements UserService {

     //User接口
     @Autowired
     private UserMapper userMapper;

     public List findUser() throws Exception {
         //调用mapper类中的selectByExample方法，如果传入类型为null，则表示无条件查找
         List users = userMapper.selectByExample(null);

         return users;
     }
 }

Controller

 package com.elin4it.ssm.controller;

 import com.elin4it.ssm.pojo.User;
 import com.elin4it.ssm.service.UserService;
 import org.springframework.beans.factory.annotation.Autowired;
 import org.springframework.stereotype.Controller;
 import org.springframework.web.bind.annotation.RequestMapping;
 import org.springframework.web.servlet.ModelAndView;

 import java.util.List;

 /**
  * Created by 烽 on 2015/7/11.
  */
 @Controller
 @RequestMapping("/user")
 public class UserController {

     //service类
     @Autowired
     private UserService userService;

     /**
      * 查找所用用户控制器方法
      * @return
      * @throws Exception
      */
     @RequestMapping("/findUser")
     public ModelAndView findUser()throws Exception{
         ModelAndView modelAndView = new ModelAndView();

         //调用service方法得到用户列表
         List users = userService.findUser();
         //将得到的用户列表内容添加到ModelAndView中
         modelAndView.addObject("users",users);
         //设置响应的jsp视图
         modelAndView.setViewName("findUser");

         return modelAndView;
     }
 }

视图

根据之前写的controller，返回的视图为findUser，所以在/WEB-INF/views中创建findUser.jsp文件，用来显示查询出来的结果
