（转） Idea SpringMVC+Spring+MyBatis+Maven整合

原文链接 http://blog.csdn.net/u011403655/article/details/46843331
原文鼠标滚动 滚的太快 看的眼睛花 真是日了狗了

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

[sql] view
plain copy







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

点击idea右侧的maven选项卡，选择其中的mybatis-generator，点击顶部的绿色按钮运行



如果没有出错的话，应该会自动生成mapper接口文件、xml文件、pojo文件。

db.properties文件

在resources/config中创建db.properties，该文件用来描述mysql连接信息

[plain] view
plain copy







jdbc.driver = com.mysql.jdbc.Driver

jdbc.url = jdbc:mysql://127.0.0.1:3306/mybatis?characterEncoding=UTF-8

jdbc.username = root

jdbc.password =

SqlMapConfig文件

在resources/config/mybatis中创建SqlMapConfig.xml文件，该文件为Mybatis的配置文件，由于跟spring整合，所以一些基础配置文件都在spring中，在这里该文件中值需要写文件的框架

[html] view
plain copy







<?xml version="1.0" encoding="UTF-8" ?>

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

[java] view
plain copy







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<User> findUser()throws Exception;

}

实现类UserServiceImpl.java

[java] view
plain copy







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<User> 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<User> users = userMapper.selectByExample(null);

return users;

}

}

Controller

[java] view
plain copy







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<User> 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

[html] view
plain copy
