编写实体及sql映射文件

SQL脚本

drop database if exists mybatis;
create database mybatis CHARACTER SET UTF8;
use mybatis;

create table dept(
dept_id int primary key auto_increment,
dept_name varchar(50),
dept_address varchar(50)
);

insert into dept(dept_name,dept_address) values('研发部一部','广州');
insert into dept(dept_name,dept_address) values('研发部二部','广州');
insert into dept(dept_name,dept_address) values('研发部三部','深圳');
select * from dept;

实体：

package zhongfucheng.entity;

import java.io.Serializable;

public class Dept implements Serializable {
private Integer deptId;
private String deptName;
private String deptAddress;
public Integer getDeptId() {
return deptId;
}
public void setDeptId(Integer deptId) {
this.deptId = deptId;
}
public String getDeptName() {
return deptName;
}
public void setDeptName(String deptName) {
this.deptName = deptName;
}
public String getDeptAddress() {
return deptAddress;
}
public void setDeptAddress(String deptAddress) {
this.deptAddress = deptAddress;
}
@Override
public String toString() {
return "Dept [deptId=" + deptId + ", deptName=" + deptName
+ ", deptAddress=" + deptAddress + "]";
}

}

映射文件

<?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="zhongfucheng.entity.DeptMapper">
<resultMap type="Dept" id="deptResultMap">
<id property="deptId" column="dept_id" />
<result property="deptName" column="dept_name" />
<result property="deptAddress" column="dept_address" />
</resultMap>
<!-- id和命名空间用来定位SQL语句，parameterType表示参数的类型，resultMap返回类型 -->
<select id="selectDept" parameterType="Integer" resultMap="deptResultMap">
<!--参数的写法#{deptID} -->
select * from dept where dept_id=#{deptID}
</select>

<insert id="insertDept" parameterType="Dept">
insert into dept(dept_name,dept_address) values(#{deptName},#{deptAddress});
</insert>

</mapper>

mybatis配置文件加载映射文件

<mappers>

编写Dao以及实现

接口

package zhongfucheng.dao;

import zhongfucheng.entity.Dept;

/**
* Created by ozc on 2017/8/8.
*/

public interface DeptDao {
Dept selectDept(Integer deptId);
int insertDept(Dept dept);
}

实现：

package zhongfucheng.dao.impl;

import org.mybatis.spring.SqlSessionTemplate;
import org.springframework.stereotype.Repository;
import zhongfucheng.entity.Dept;

import javax.annotation.Resource;

/**
* Created by ozc on 2017/8/8.
*/
@Repository("deptDao")
public class DeptDaoImpl implements zhongfucheng.dao.DeptDao {

@Resource
private SqlSessionTemplate sqlSessionTemplate;

/**
* 根据部门编号查询部门信息
* @param deptId 部门编号
* @return 部门信息
*/
@Override
public Dept selectDept(Integer deptId){
Dept dept=  sqlSessionTemplate.selectOne("zhongfucheng.entity.DeptMapper.selectDept", deptId);
return dept;
}
/**
* 添加部门信息
* @param dept 部门信息
* @return 添加成功的记录数
*/
@Override
public int insertDept(Dept dept){
System.out.println("------dao.dept:"+dept);
return sqlSessionTemplate.insert("zhongfucheng.entity.DeptMapper.insertDept", dept);
}
}

测试spring与mybatis整合

import org.junit.AfterClass;
import org.junit.BeforeClass;
import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import zhongfucheng.dao.impl.DeptDaoImpl;
import zhongfucheng.entity.Dept;

/**
* Created by ozc on 2017/8/8.
*/
public class TestDeptDao {

//@Resource //这里没法使用，后继版本有其它方式可以注入
static private DeptDaoImpl deptDao;
@BeforeClass
public static void setUpBeforeClass() throws Exception {
ApplicationContext context =new ClassPathXmlApplicationContext("applicationContext.xml");
deptDao=(DeptDaoImpl) context.getBean("deptDao");
}

@AfterClass
public static void tearDownAfterClass() throws Exception {
}

@Test
public void testSelectDept() {
System.out.println(deptDao.selectDept(1));
}

@Test
public void testInsertDept() {
Dept dept=new Dept();
//dept.setDeptId(117);
dept.setDeptName("name117");
dept.setDeptAddress("address117");
System.out.println("受影响行数："+deptDao.insertDept(dept));
}
}

整合SpringMVC

编写Action

package zhongfucheng.action;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import zhongfucheng.dao.impl.DeptDaoImpl;
import zhongfucheng.entity.Dept;

import javax.annotation.Resource;

/**
* Created by ozc on 2017/8/8.
*/
@Controller
@RequestMapping(value="/dept")
public class DeptAction {
@Resource
private DeptDaoImpl deptDao;

@RequestMapping(value="/insert")
public String insert(Dept dept){

System.out.println("---action.dept:"+dept);
deptDao.insertDept(dept);
return "forward:/jsp/main.jsp";
}
}

测试SSI整合

index.jsp页面

<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<html>
<head>
</head>
<body>
<form action="dept/insert.action" method="post">
名称：<input type="text"   name="deptName"><br>
地址：<input type="text" name="deptAddress"><br>
<input type="submit" value="ok">
</form>
</body>
</html>

main.jsp页面：

<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<html>
<head>
</head>
<body>
this is main jsp
</body>
</html>

优化

如果想要Spring与Mybatis更加完美地结合，其实我们的Dao并不需要写实现，直接写接口和映射文件就行了，这样一来，我们就可以舍弃DaoImpl了。

在Spring配置文件中加入以下的代码：

<!-- 配置 转换器，对于在basePackage设置的包（包括子包）下的接口类，
如果接口类的全类名在Mapper.xml文件中和定义过命名空间一致，
将被转换成spring的BEAN，在调用的地方通过@Autowired方式将可以注入接口实例 -->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="sqlSessionFactory" ref="sqlSessionFactory" />

<!--这里包名留意要不要改-->
<property name="basePackage" value="zhongfucheng.dao" />
</bean>

我们的映射文件中把命名空间写成是Dao的全路径

//Dao的全路径，那么Spring就会自动帮我们创建对象，注入进去
<mapper namespace="zhongfucheng.dao.DeptDao">
<resultMap type="Dept" id="deptResultMap">
<id property="deptId" column="dept_id" />
<result property="deptName" column="dept_name" />
<result property="deptAddress" column="dept_address" />
</resultMap>

<!-- id和命名空间用来定位SQL语句，parameterType表示参数的类型，resultMap返回类型 -->
<select id="selectDept" parameterType="Integer" resultMap="deptResultMap">
<!--参数的写法#{deptID} -->
select * from dept where dept_id=#{deptID}
</select>

<insert id="insertDept" parameterType="Dept">
insert into dept(dept_name,dept_address) values(#{deptName},#{deptAddress});
</insert>

</mapper>

在配置工厂的时候，我们可以配置mapperLocations属性，这样一来，我们就不用在Mybatis中逐个加载配置文件了。

<!-- 配置session工厂 -->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource" />
<!--这里的路径和名字留意要不要改-->
<property name="configLocation" value="classpath:myBatis-config.xml" />

<!--配置扫描式加载SQL映射文件,记得去掉mybatis-config配置，使用了这个，在Mybatis配置文件中就不用加载对应的映射文件了-->
<!--这里留意路径是否要改-->
<property name="mapperLocations" value="classpath:zhongfucheng/dao/*.xml"/>
</bean>
