Idea SpringMVC+Spring+MyBatis+Maven+Tomcat调整

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，FinishIdea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 frameworkaspectj事务c3p0数据源servlet/jsp apijunit4mybatismybatis spring整合mysql driverjstl

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(首先在mysql库中创建名字叫ssm的database库，可以生成.sql文件将下面的代码复制进去，通过在这个库下导入sql文件建user表，或者直接在ssm库下的窗口里粘贴创建user表)

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generatorConfig.xml代码清单

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

</context>
</generatorConfiguration>

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

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

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

<configuration>

</configuration>

SpringMVC配置文件

在resources/config/spring中创建springmvc.xml文件

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

在resources/config/spring中创建applicationContext-dao.xml、application-service.xml、applicationContext-transaction.xml文件applicationContext-dao.xml

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<User> 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 此处注入UserMapper时需要在UserMapper接口上添加<span style="font-family: Arial, Helvetica, sans-serif;">@Component进行依赖注入</span>
@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

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;
}
}

<span style="font-size:24px;"><strong>配置tomcat</strong></span>

打开面板 Run -- 》Edit Configurations，点+号，选择 Tomcat server --> Local --> </span>

输入tomcat名称和配置信息后，点击“Deployment”标签页，点击下面的+号，在弹出的列表中选择“Artifact”, 弹出提示框, 选择要deployment的project编辑 Application context的名称，点击OK就可完成Tomcat配置。

点击下面的绿色箭头或右上角的tomcat启动箭头，即可启动tomcat部署的project。启动后会自动跳转到浏览器可以通过http://localhost:8080/工程名字/user/findUser访问跑起来！

<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
