　　参考 http://www.cnblogs.com/wushiqi54719880/archive/2011/07/27/2117944.html
　　1、创建一个model对象

package adtec.dbtest.model;
public class K_user {
private Integer id;
private String name;
private Integer age;
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;
}
}
　　2、新建一个dao对象，对数据库的操作

package adtec.dbtest.dao;
import adtec.dbtest.model.K_user;
public interface K_userDao {
public void insert(K_user k_user);
}
　　3、创建与dao对象对应的xml操作文件（主要是执行它来操作数据库）

<?x ml 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="adtec.dbtest.dao.K_userDao">
<insert id="insert" parameterType="adtec.dbtest.model.K_user">
INSERT INTO K_USER(NAME,AGE) values(#{name},#{age})
</insert>
</mapper>
　　备注：xml文件名称要与dao文件名称对应，例如K_userDao对应的就是K_userDao.xml文件，id名称要与dao 的方法对应起来。
　　编写mybatis的配置文件：

<?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>
<mappers>
<mapper resource="adtec/dbtest/dao/K_userDao.xml"/>
</mappers>
</configuration>
　　4、编写一个service接口，定义方法

package adtec.dbtest.service;
import adtec.dbtest.model.K_user;
public interface K_userService {
public void   insert(K_user k_user);
}
　　5、对service接口的实现，主要目的是为了处理多个功能，方便事务的处理

package adtec.dbtest.service.imp;
import adtec.dbtest.dao.K_userDao;
import adtec.dbtest.model.K_user;
import adtec.dbtest.service.K_userService;
public class K_userServiceImp implements K_userService{
K_userDao k_userDao;
public K_userDao getK_userDao() {
return k_userDao;
}
public void setK_userDao(K_userDao k_userDao) {
this.k_userDao = k_userDao;
}
@Override
public void insert(K_user k_user) {
k_userDao.insert(k_user);
}
}
　　6、spring配置文件

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:aop="http://www.springframework.org/schema/aop"
xmlns:tx="http://www.springframework.org/schema/tx" xmlns:jdbc="http://www.springframework.org/schema/jdbc"
xmlns:context="http://www.springframework.org/schema/context" xmlns:p="http://www.springframework.org/schema/p"
xsi:schemaLocation="
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd
http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
http://www.springframework.org/schema/jdbc http://www.springframework.org/schema/jdbc/spring-jdbc-3.0.xsd

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

<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
<property name="driverClassName">
<value>com.mysql.jdbc.Driver</value>
</property>
<property name="url">
<value>jdbc:mysql://127.0.0.1:3306/hb</value>
</property>
<property name="username">
<value>root</value>
</property>
<property name="password">
<value>admin</value>
</property>
</bean>
<!--
如果不是在src目录下面，而是在WEB-INF/config/mybatis目录下面
<property name="configLocation" value="classpath:../config/mybatis/MyBatis-Configuration.xml"></property>
-->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource"></property>
<property name="configLocation" value="classpath:MyBatis-Configuration.xml"></property>
</bean>
<bean id="tm" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource"></property>
</bean>
<tx:annotation-driven transaction-manager="tm" />
<bean class="adtec.dbtest.service.imp.K_userServiceImp" name="k_userservice">
<property name="k_userDao" ref="k_userDao"></property>
</bean>
<!-- 配置dao层的接口，将接口提供给servivc使用 -->
<bean id="k_userDao" class="org.mybatis.spring.mapper.MapperFactoryBean">
<property name="mapperInterface" value="adtec.dbtest.dao.K_userDao"></property>
<property name="sqlSessionFactory" ref="sqlSessionFactory"></property>
</bean>
</beans>
　　7、编写一个测试类

package adtec.dbtest.junit;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import adtec.dbtest.model.K_user;
import adtec.dbtest.service.K_userService;
public class Test {
@org.junit.Test
public void insert() {
ApplicationContext ap = new ClassPathXmlApplicationContext("applicationContext.xml");
K_userService us = (K_userService) ap.getBean("k_userservice");
K_user u = new K_user();
u.setName("555");
u.setAge(555);
us.insert(u);
//Integer.parseInt("sss");
}
}
