Spring+Ibatis集成开发实例

首先简历数据库demo(本文选mysql)

数据库脚本：

CREATE TABLE `ibatis` (
`id` varchar(20) NOT NULL,
`name` varchar(20) default NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=gb2312;

insert into ibatis values("1","1");
insert into ibatis values("2","2");

DAO接口：

package ch10.SpringAndIbatis;

import java.util.List;

Ibatis配置文件：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE sqlMapConfig
PUBLIC "-//iBATIS.com//DTD SQL Map Config 2.0//EN"
"http://www.ibatis.com/dtd/sql-map-config-2.dtd">
<sqlMapConfig>

<sqlMap resource="ch10/SpringAndIbatis/Ibatis.xml" />

</sqlMapConfig>

ibatis sql map文件ibatis.xml：

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE sqlMap PUBLIC "-//ibatis.apache.org//DTD SQL Map 2.0//EN" "http://ibatis.apache.org/dtd/sql-map-2.dtd" >
<sqlMap >
<typeAlias type="ch10.SpringAndIbatis.Ibatis" alias="user"/>
<resultMap id="ibatisTest" class="user" >
<result column="id" property="id" jdbcType="VARCHAR" />
<result column="name" property="name" jdbcType="VARCHAR" />
</resultMap>

<!-- 获得全查询列表 -->
<select id="getAllUsers" resultMap="ibatisTest">
select * from Ibatis
</select>

<!-- 依据username获得用户对象 -->
<select id="getUsersByName" resultMap="ibatisTest">
select * from Ibatis where name=#value#
</select>

<!-- 依据id获得用户对象 -->
<select id="getUsersById" resultMap="ibatisTest">
select * from Ibatis where id=#value#
</select>

<!-- 新增用户对象 -->
<insert id="insertUsers" parameterClass="user">
insert into ibatis (id,name) values (#id#,#name#)
</insert>

<!-- 删除用户对象 -->
<delete id="deleteUsers">
delete from ibatis where id=#value#
</delete>

<!-- 更新用户对象 -->
<delete id="updateUsers" parameterClass="user">
update ibatis set name=#name# where id=#id#
</delete>
</sqlMap>

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"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd">
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
<property name="driverClassName">
<value>com.mysql.jdbc.Driver</value>
</property>
<property name="username">

</property>
<property name="password">
<value>1234</value>
</property>
<property name="url">
<value>jdbc:mysql://localhost:3306/spring</value>
</property>
</bean>

<bean id="sqlMapClient" class="org.springframework.orm.ibatis.SqlMapClientFactoryBean">
<!-- 此处应注入ibatis配置文件，而非sqlMap文件，否则会出现“there is no statement.....异常” -->
<property name="configLocation">
<value>ch10/SpringAndIbatis/sqlMapConfig.xml</value>
</property>

</bean>

<bean id="testDAO" class="ch10.SpringAndIbatis.TestDAO">
<property name="dataSource">
<ref bean="dataSource"/>
</property>
<property name="sqlMapClient">
<ref bean="sqlMapClient"/>
</property>
</bean>

</beans>

DAO实现类：

package ch10.SpringAndIbatis;

import java.util.List;

import org.springframework.orm.ibatis.support.SqlMapClientDaoSupport;

domain对象

package ch10.SpringAndIbatis;

測试代码：

package ch10.SpringAndIbatis;

import java.util.ArrayList;
import java.util.Iterator;
import java.util.List;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

測试结果：

依据username获得用户对象

依据id获得用户对象
