Spring+Ibatis集成开发实例
Spring+Ibatis集成开发实例
简单流程介绍：
1．导包：
线程池
commons-collections-3.1.jar
commons-dbcp-1.2.2.jar
commons-pool.jar
ibatis框架
ibatis-2.3.0.677.jar
数据库驱动包
mysql-connector-java-5.1.13-bin.jar
springmvc
spring-webmvc.jar
spring框架包
commons-logging.jar
spring.jar
2.web.xml配置Spring的前端控制器DispatcherServlet。
3.添加Spring配置文件applicationContext.xml。
4.编写实体类，以及对应的实体类描述文件。
5.添加ibatis配置文件，并引入实体类描述文件。
6.编写对应功能接口IDAO，并填写实体类描述文件中的SQL语句。
7.编写实现类DAOImpl，extends SqlMapClientDaoSupport implements IDAO{}
8.编写测试类。
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"?>

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("-----------------");
}
}
