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;

public interface IDAO ...{
public List getList();
public Ibatis getByName(String name);
public Ibatis getById(String id);
public void save(Ibatis ibatis);
public void delete(String id);
public void update(Ibatis ibatis);
}
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>

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

<!-- 根据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 name="password">

</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;

public class TestDAO extends SqlMapClientDaoSupport implements IDAO ...{

public void delete(String id) ...{
getSqlMapClientTemplate().delete("deleteUsers", id);
}

public Ibatis getById(String id) ...{
return (Ibatis)getSqlMapClientTemplate().queryForObject("getUsersById",id);
}

public Ibatis getByName(String name) ...{

return (Ibatis)getSqlMapClientTemplate().queryForObject("getUsersByName",name);
}

public List getList() ...{
return getSqlMapClientTemplate().queryForList("getAllUsers",null);
}

public void save(Ibatis ibatis) ...{
getSqlMapClientTemplate().insert("insertUsers",ibatis);
}

public void update(Ibatis ibatis) ...{
getSqlMapClientTemplate().update("updateUsers", ibatis);
}

}
domain对象

package ch10.SpringAndIbatis;

public class Ibatis ...{

private String id;
private String name;
public String getId() ...{
return id;
}
public void setId(String id) ...{
this.id = id;
}
public String getName() ...{
return name;
}
public void setName(String name) ...{
this.name = name;
}
public Ibatis()...{

}
public Ibatis(String id, String name) ...{
super();
this.id = id;
this.name = name;
}
}
测试代码：

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;

public class Test ...{

/** *//**
* @param args
*/
public static void main(String[] args) ...{
ApplicationContext context=new ClassPathXmlApplicationContext("ch10/SpringAndIbatis/applicationContext.xml");
TestDAO testDAOImpl=(TestDAO)context.getBean("testDAO");

//获得全查询列表
System.out.println("获得全查询列表");
List result=new ArrayList();
result=testDAOImpl.getList();
for (Iterator iter = result.iterator(); iter.hasNext();) ...{
Ibatis element = (Ibatis) iter.next();
System.out.println(element.getName());

}

//根据用户名获得用户对象
System.out.println("根据用户名获得用户对象");
Ibatis ibatis=testDAOImpl.getByName("1");
System.out.println(ibatis.getName());

//根据id获得用户对象
System.out.println("根据id获得用户对象");
Ibatis ibatis1=testDAOImpl.getById("1");
System.out.println(ibatis.getName());

//新增用户对象
System.out.println("-----------------");
System.out.println("新增用户对象前");
List result1=new ArrayList();
result1=testDAOImpl.getList();
for (Iterator iter = result1.iterator(); iter.hasNext();) ...{
Ibatis element = (Ibatis) iter.next();
System.out.println(element.getName());

}
testDAOImpl.save(new Ibatis("3","3")); //新增用户
System.out.println("新增用户对象后");
List result2=new ArrayList();
result2=testDAOImpl.getList();
for (Iterator iter = result2.iterator(); iter.hasNext();) ...{
Ibatis element = (Ibatis) iter.next();
System.out.println(element.getName());
}
System.out.println("-----------------");

//删除用户对象
System.out.println("-----------------");
System.out.println("删除用户对象前");
List result3=new ArrayList();
result3=testDAOImpl.getList();
for (Iterator iter = result3.iterator(); iter.hasNext();) ...{
Ibatis element = (Ibatis) iter.next();
System.out.println(element.getName());

}
testDAOImpl.delete("3"); //删除用户
System.out.println("删除用户对象后");
List result4=new ArrayList();
result4=testDAOImpl.getList();
for (Iterator iter = result4.iterator(); iter.hasNext();) ...{
Ibatis element = (Ibatis) iter.next();
System.out.println(element.getName());
}
System.out.println("-----------------");

//更新用户对象
System.out.println("-----------------");
System.out.println("更新用户对象前");
List result5=new ArrayList();
result5=testDAOImpl.getList();
for (Iterator iter = result5.iterator(); iter.hasNext();) ...{
Ibatis element = (Ibatis) iter.next();
System.out.println(element.getName());

}

Ibatis ibatis3=testDAOImpl.getById("1");
ibatis3.setName("new1");
testDAOImpl.update(ibatis3);//更新用户对象

System.out.println("更新用户对象后");
List result6=new ArrayList();
result6=testDAOImpl.getList();
for (Iterator iter = result6.iterator(); iter.hasNext();) ...{
Ibatis element = (Ibatis) iter.next();
System.out.println(element.getName());
}
System.out.println("-----------------");

}

}
测试结果：
