spring和mybatis整合，spring获取sqlsession对象

这里不做过多解释，主要是把spring和mybatis整合起来，自己在网上找了很久发现获取sqlsession对象的方法比较少

首先还是jar文件一个不能少这个可以自己准备也可以去我上传的资源中找到

mysql表

下面直接上配置

1、配置User类（工具类）

package domain;

import org.apache.ibatis.session.SqlSessionFactory;

import org.mybatis.spring.SqlSessionTemplate;

import com.sun.org.apache.bcel.internal.generic.Select;

public class User {

private SqlSessionTemplate sqlsession;

public SqlSessionTemplate getSqlsession() {

return sqlsession;

}

public void setSqlsession(SqlSessionTemplate sqlsession) {

this.sqlsession = sqlsession;

}

public void getUser(int id){

System.out.println(sqlsession.selectOne("mapping.userMapper.getUser",id));

}

}

2、配置UserMapper.xml

Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd

">

select * from user where id=#{id}

3、spring.xml文件

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:aop="http://www.springframework.org/schema/aop"

xmlns:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx"

xsi:schemaLocation="http://www.springframework.org/schema/beans

http://www.springframework.org/schema/beans/spring-beans-3.0.xsd

http://www.springframework.org/schema/aop

http://www.springframework.org/schema/aop/spring-aop-3.0.xsd

http://www.springframework.org/schema/context

http://www.springframework.org/schema/context/spring-context-3.0.xsd

http://www.springframework.org/schema/tx

http://www.springframework.org/schema/tx/spring-tx-3.0.xsd

">

<数据源>

class="org.springframework.jdbc.datasource.DriverManagerDataSource">

org.gjt.mm.mysql.Driver

jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=UTF-8

root

root

4、配置mybatisconf.xml文件

"-//mybatis.org//DTD

Config 3.0//EN"

"http://mybatis.org/dtd/mybatis-3-config.dtd

">

5、配置Test测试类

package mapping;

import org.springframework.context.support.ClassPathXmlApplicationContext;

import domain.User;

public class Test1 {

public static void main(String[] args) {

ClassPathXmlApplicationContext ac = new ClassPathXmlApplicationContext("spring.xml");

User user = (User)ac.getBean("getuser");

user.getUser(1);

}

}

测试结果
