【MyBatis】MyBatis+SpringMVC+EasyUI整合分页

标签：spring mvc   mybatis   easyui   分页   

一、介绍

环境：MyBatis 3.0.x+Spring 3.0.x+EasyUI

采用SpringMVC+MyBatis框架整合的分页Demo，用的是首页这个：http://www.jeasyui.com/demo/main/index.php

Demo结构如下：

再看一下效果：

二、项目详解：

前提是首先把所有的jar包导入进入，不管是用Maven或者手动都可以。

1、首先建立javabean，User.java：

package com.bee.po;

public class User {
	private int id;
	private String name;
	private String password;
	private String sex;
	private int age;
	private String address;
	
	@Override
	public String toString() {
		return "User [id=" + id + ", name=" + name + ", password=" + password
				+ ", sex=" + sex + ", age=" + age + ", address=" + address
				+ "]";
	}
	//省略setter和getter方法
}

2、然后建立dao层接口类，UserMapper以及UserMapper.xml（因为MyBatis是接口编程，只需要实现mapper而不用实现dao接口）

UserMapper.java：

package com.bee.dao;
import java.util.List;
import com.bee.po.User;

public interface UserMapper {
	/**
	 * 通过姓名查找用户
	 * @param name 用户名
	 * @return 返回用户对象
	 */
	public User findUserByName(String name);
	
	/**
	 * 查询所有用户，显示列表
	 */
	public List<User> findUsersList();
	/**
	 * 根据页数和记录数，返回记录
	 */
	public List<User> findUsersListByPage(int start,int end);
	/**
	 * 添加用户
	 */
	public void addUser(User user);
	/**
	 * 修改用户
	 */
	public void updateUser(User user);
	/**
	 * 根据ID删除用户
	 */
	public void deleteUser(int id);
	/**
	 * 插入学生自动生成主键
	 */
	public 	String createStudentAutoKey(User user);
	
}

根据UserMapper接口，我们可以写出映射文件UserMapper.xml（直接写在Dao层了，这样写不是太好）：

<?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.bee.dao.UserMapper">
	<!-- 用户列表List -->
	<resultMap type="User" id="resultListUser">
		<id column="id" property="id" />
		<result column="name" property="name" />
		<result column="password" property="password" />
		<result column="sex" property="sex" />
		<result column="address" property="address" />
	</resultMap>
	
	<!-- 通过名称查找 -->
	<select id="findUserByName" parameterType="String" resultType="User">
		select * 
		from user where name=#{name}
	</select>
	
	<!-- 查找用户列表 -->
	<select id="findUsersList" resultMap="resultListUser">
		select * from user
	</select>
	<!-- 根据页数和记录数返回查找记录 -->
	<select id="findUsersListByPage"  resultMap="resultListUser">
		select * from user limit #{0},#{1}
	</select>
	
	<!-- 添加用户 -->
	<insert id="addUser" parameterType="User" useGeneratedKeys="true" 
		keyProperty="id">
		insert into user(name,password,sex,age,address)
			values(#{name},#{password},#{sex},#{age},#{address})	
	</insert>
	
	<!-- 更新用户 -->
	<update id="updateUser" parameterType="User">
		update user set 
		<if test="name != null">
			name=#{name},
		</if>
		<if test="password != null">
			password=#{password},
		</if>
		<if test="sex != null">
			sex=#{sex},
		</if>
		<if test="age != null">
			age=#{age},
		</if>
		<if test="address != null">
			address=#{address}
		</if>
		where id=#{id}
	</update>
	
	<!-- 删除用户 -->
	<delete id="deleteUser" parameterType="int">
		delete from user where id=#{id}
	</delete>
	
	<!-- 插入学生，自动生成主键 -->
	<insert id="createStudentAutoKey" parameterType="User" keyProperty="id">  
		<selectKey keyProperty="id" resultType="String" order="BEFORE">
			select user
		</selectKey>
		insert into user(id,name,password,sex,age,address) 
		values(#{id},#{name},#{password},#{sex},#{age},#{address})
	</insert>
</mapper>

<?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>
	<typeAliases>
		<!-- 给实体类起别名 -->
		<typeAlias type="com.bee.po.User" alias="User"/>
	</typeAliases>

	<!--装载Mapper -->
	<mappers>
		<mapper resource="com/bee/dao/UserMapper.xml" />
	</mappers>
</configuration>

下边就是要把所有的资源添加到Spring容器中，在src根下配置applicationContext.xml文件：
