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> <!-- 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"> <value>root</value> </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;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;}}
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;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()); } //依据username获得用户对象 System.out.println("依据username获得用户对象"); Ibatis ibatis=testDAOImpl.getByName("1"); System.out.println(ibatis.getName()); //依据id获得用户对象 System.out.println("依据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("-----------------"); }}
