IDEA之Maven搭建Spring4 SpringMVC4 Mybatis3
首先打开Mysql的图形界面工具进行建库建表，当然也可以使用cmd黑窗口命令形式进行建库建表。
create database kaoshi;
use kaoshi;
create table k_dept(
id int(11) auto_increment primary key,
name varchar(30),
age int(11),
birdate date);
INSERT INTO `k_dept` VALUES ('1', '张三', '56', '2017-08-07');
INSERT INTO `k_dept` VALUES ('2', '李四', '47', '2017-09-04');
INSERT INTO `k_dept` VALUES ('3', '王五', '36', '2017-09-05');
打开IDEA，创建Maven项目。
pom.xml 文件如下。

先把配置文件整理好。 db.properties。位置在resources目录下。

spring-mvc.xml 。位置在resources目录下。

然后在 web.xml 文件配置。

配置文件整理好了，接下来就可以编写Java代码了。
1、Entity实体对象Dept.java
package com.zhenqi.entity;
import java.util.Date;
/**
* Created by wuming on 2017/9/8.
*/
public class Dept {
private Integer id;
private String name;
private Integer age;
private Date birDate;
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public Integer getAge() {
return age;
}
public void setAge(Integer age) {
this.age = age;
}
public Date getBirDate() {
return birDate;
}
public void setBirDate(Date birDate) {
this.birDate = birDate;
}
}
2、Dao层
而后是Dao接口与Mapper xml文件。
DeptDao.java
package com.zhenqi.dao;
import com.zhenqi.entity.Dept;
import java.util.List;
/**
* Created by wuming on 2017/9/8.
*/
public interface DeptDao {
//查找所有内容
public List<Dept> findAll();
}
Dept.xml 其位置 com/zhenqi/dao目录下。
<?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">
<mapper namespace="com.zhenqi.dao.DeptDao">
<resultMap id="deptAll" type="com.zhenqi.entity.Dept" >
<id property="id" column="IID" />
<result property="name" column="name" />
<result property="age" column="age" />
<result property="birDate" column="birdate" />
</resultMap>
<!-- 查找 -->
<select id="findAll" resultMap="deptAll">
select * from k_dept
</select>
</mapper>
3.Service层，也就是处理业务相关的。DeptService.java接口文件如下：
package com.zhenqi.service;
import com.zhenqi.entity.Dept;
import java.util.List;
/**
* Created by wuming on 2017/9/8.
*/
public interface DeptService {
//查找所有内容
public List<Dept> findall();
}
实现类 DeptServiceImpl.java 如下：
package com.zhenqi.service.impl;
import com.zhenqi.dao.DeptDao;
import com.zhenqi.entity.Dept;
import com.zhenqi.service.DeptService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import java.util.List;
/**
* Created by wuming on 2017/9/8.
*/
@Service("deptService")
public class DeptServiceImpl implements DeptService {
//注入dao对象
@Autowired
private DeptDao deptDao;
public List<Dept> findall() {
return deptDao.findAll();
}
}
4、Controller层，也就是所谓的控制层。DeptController.java文件如下：
package com.zhenqi.controller;
import com.zhenqi.entity.Dept;
import com.zhenqi.service.DeptService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.RequestMapping;
import javax.servlet.http.HttpServletRequest;
import java.util.List;
/**
* Created by wuming on 2017/9/8.
*/
@Controller
@RequestMapping("/dept")
public class DeptController {
@Autowired
private DeptService deptService;
@RequestMapping("/find")
public String find(ModelMap model, HttpServletRequest request){
List<Dept> deptList=deptService.findall();
//将获取到的数据存入ModelMap中，以便页面取出
model.addAttribute("depts", deptList);
return "dept";
}
}
5、view层，就是jsp或html。dept.jsp文件如下，其位置在 WEB-INF/views/ 目录下。
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<%@ page isELIgnored="false"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Dept</title>
</head>
<body>
<table>
<tr>
<th>ID</th>
<th>姓名</th>
<th>年龄</th>
<th>生日</th>
</tr>
<c:forEach var="dept" items="${depts}">
<tr>
<td><c:out value="${dept.id}"/></td>
<td><c:out value="${dept.name}"/></td>
<td><c:out value="${dept.age}"/></td>
<td><c:out value="${dept.birDate}"/></td>
</tr>
</c:forEach>
</table>
</body>
</html>
启动Tomcat容器，如果不知怎么在IDEA中部署maven项目到Tomcat上的朋友，可参考文章： IDEA运行Maven项目部署tomcat上
访问浏览器， http://localhost:8080/kaoshi-ssm/dept/find
至此，maven搭建ssm框架就先告一段落了。
