1、創建一個model對象

      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、新建一個dao對象，對數據庫的操作

      package adtec.dbtest.dao;

import adtec.dbtest.model.K_user;

public interface K_userDao {

	public void insert(K_user k_user);
}
    

?

3、創建與dao對象對應的xml操作文件（主要是執行它來操作數據庫）

      <?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>
    

?

備注：xml文件名稱要與dao文件名稱對應，例如K_userDao對應的就是K_userDao.xml文件，id名稱要與dao 的方法對應起來。

?

編寫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、編寫一個service接口，定義方法

      package adtec.dbtest.service;

import adtec.dbtest.model.K_user;

public interface K_userService {

	public void   insert(K_user k_user);
}
    

?

5、對service接口的實現，主要目的是為了處理多個功能，方便事務的處理

      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/tx http://www.springframework.org/schema/tx/spring-tx-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目錄下面，而是在WEB-INF/config/mybatis目錄下面
<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層的接口，將接口提供給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、編寫一個測試類

      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");
	}
}
