Spring+Ibatis集成开发实例!

Spring+Ibatis集成开发实例

首先建立数据库demo，然后建表(本文选mysql)

建表数据库脚本：

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 ","来宾");
insert into ibatis values (" 2 ","用户");

DAO接口：

package com.etong.community.test.dao;

import java.util.List;

import com.etong.community.test.daomain.Ibatis;

public interface IbatisDAO ... {

publicListgetList();

publicIbatisgetByName(Stringname);

publicIbatisgetById(Stringid);

publicvoidsave(Ibatisibatis);

publicvoiddelete(Stringid);

publicvoidupdate(Ibatisibatis);

}

Ibatis配置文件(sqlMap-config.xml)：

<? xmlversion="1.0"encoding="UTF-8" ?>
<! DOCTYPEsqlMapConfigPUBLIC"-//iBATIS.com//DTDSQLMapConfig2.0//EN"
"http://www.ibatis.com/dtd/sql-map-config-2.dtd" >

< sqlMapConfig >
< sqlMap resource ="com/etong/community/test/dao/ibatis/maps/ibatis.xml" />
</ sqlMapConfig >

ibatis sql map的文件ibatis.xml：

<? xmlversion="1.0"encoding="UTF-8" ?>
<! DOCTYPEsqlMapPUBLIC"-//ibatis.apache.org//DTDSQLMap2.0//EN""http://ibatis.apache.org/dtd/sql-map-2.dtd" >
< sqlMap >
< typeAlias type ="com.etong.community.test.daomain.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" >
SELECTID,NAMEFROMIBATIS
</ select >

<!-- 根据用户名获得用户对象 -->
< select id ="getUsersByName" resultMap ="ibatisTest" >
SELECTID,NAMEFROMIBATISWHERENAME=#value#
</ select >

<!-- 根据id获得用户对象 -->
< select id ="getUsersById" resultClass ="user" >
SELECTID,NAMEFROMIBATISWHEREID=#value#
</ select >

<!-- 新增用户对象 -->
< insert id ="insertUsers" parameterClass ="user" >
INSERTINTOIBATIS(ID,NAME)VALUES(#id#,#name#)
</ insert >

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

<!-- 更新用户对象 -->
< update id ="updateUsers" parameterClass ="user" >
UPDATEIBATISSETNAME=#name#WHEREID=#id#
</ update >
</ sqlMap >

spring配置文件(applicationContext.xml)

<? xmlversion="1.0"encoding="GB18030" ?>
< beans xmlns ="http://www.springframework.org/schema/beans"

DAO实现类：

package com.etong.community.test.dao.ibatis;

import java.util.List;

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

import com.etong.community.test.dao.IbatisDAO;

/***/ /**

public class SqlMapIbatisDAO extends SqlMapClientDaoSupport implements IbatisDAO ... {

/**//*

*

*/
publicvoiddelete(Stringid)...{
getSqlMapClientTemplate().delete("deleteUsers",id);

}

/**//*
*(non-Javadoc)
*
*@seecom.etong.community.test.IbatisDAO#getById(java.lang.String)
*/
publicIbatisgetById(Stringid)...{
return(Ibatis)getSqlMapClientTemplate().queryForObject(
"getUsersById",id);
}

/**//*

}

/**//*

}

*/
publicvoidupdate(Ibatisibatis)...{
getSqlMapClientTemplate().update("updateUsers",ibatis);

}

}

domain对象

package com.etong.community.test.daomain;

import java.io.Serializable;

public class Ibatis implements Serializable ... {
