本文通过一个具体的示例展示了如何将Spring框架与iBatis进行整合，包括配置数据库连接、定义DAO接口及实现、编写iBatis映射文件等步骤，并提供了完整的测试代码。

开发环境如以下：

数据库 mysql 5.x

sql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");

jar包

mysql-connector-java-5.1.5-bin.jar

commons-dbcp-1.4.jar

commons-logging-1.0.4.jar

commons-pool-1.6.jar

ibatis-2.3.0.677.jar

mysql-connector-java-5.1.5-bin.jar

spring-aop-3.2.0.RELEASE.jar

spring-aspects-3.2.0.RELEASE.jar

spring-beans-3.2.0.RELEASE.jar

spring-context-3.2.0.RELEASE.jar

spring-core-3.2.0.RELEASE.jar

spring-expression-3.2.0.RELEASE.jar

spring-jdbc-3.2.0.RELEASE.jar

spring-orm-3.2.0.RELEASE.jar

spring-tx-3.2.0.RELEASE.jar

spring-web-3.2.0.RELEASE.jar

spring-webmvc-3.2.0.RELEASE.jar

所有的jar包我已经上传

在src下新建ch10.SpringAndIbatis包，所有的测试文件都在这个包下，废话不多说了，直接贴代码

1.Ibatis.java

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;
}
}

2.IDAO.java

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);
}

3.TestDao.java

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);
    }

}

4.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" >

  <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>

5.sqlMapConfig.xml

<?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>

6.applicationContext.xml，注意修改你数据库配置
