【IT168 技术专栏】
准备工作：
1.hibernate3
到这下载hibernate3:http://sourceforge.net/project/showfiles.phpgroup_id=40712&package_id=
127784&release_id=403223
2.mysql (注意一定要用mysql5.0和最新驱动)
mysql官方网站http://www.mysql.com/
过程：
1.建张表
CREATE TABLE `proctest` (
`id` int ( 11 ) NOT NULL auto_increment,
`Name` varchar ( 20 ) default '''''' ,
`age` int ( 11 ) default NULL ,
`address` varchar ( 50 ) default '' ,
PRIMARY KEY (`id`)
) ENGINE = InnoDB DEFAULT CHARSET = gb2312;
2.插入几条记录
INSERT INTO `proctest` VALUES ( 1 , ' tom ' , 22 , 'http://www.blogjava.net ' );
INSERT INTO `proctest` VALUES ( 2 , ' wujun ' , 25 , 'http://www.blogjava.net/wujun ' );
INSERT INTO `proctest` VALUES ( 3 , ' jerry ' , 30 , ' 深圳 ' );
INSERT INTO `proctest` VALUES ( 4 , ' wujun ' , 40 , ' 南昌 ' );
3.创建存储过程
-- 这只是一个例子，就来个简单存储过程
create PROCEDURE testProc()
begin
select * from proctest;
end ;
打开eclipce新建个java工程，记得把hiberbate3类库也一起加进去。
看下结构图：
新建UserVO.java文件
package net.wj.proc.vo;
public class UserVO {
private int id;
private String name;
private int age;
private String address;
public UserVO()
{}
顺便把它相对应的配置文件也写上。
UserVO.hbm.xml
<?xml version="1.0" encoding='UTF-8'?>

<!--sql查询-->
<sql-query name="select">
<![CDATA[select {usr.*} from proctest usr ]]>

</sql-query>
<!--调用存储过程就在这里配了-->
<sql-query name="getUser" callable="true">
<return alias="user" class="net.wj.proc.vo.UserVO">
<return-property name="id" column="id" />
<return-property name="name" column="name" />
<return-property name="age" column="age" />
<return-property name="address" column="address" />
</return>
<!--这里就是我们刚刚创建的存储过程名-->
{call testProc()}
</sql-query>
</hibernate-mapping>
测试代码
package net.wj.proc.test;
import java.util.List;
import org.hibernate.*;
import org.hibernate.cfg.*;
import net.wj.proc.vo.*;
import org.apache.log4j.*;
public class ProcTest {
/** *//**
* @param args
*/
Logger log=Logger.getLogger(this.getClass());
public ProcTest()
{}
public static void main(String[] args) {
System.out.print("start.............................");
ProcTest tt=new ProcTest();
// tt.LoadAll();
// tt.ExampleSelect();
tt.ExampleProc();
}
//得到Session,
public Session getSession()
{
try
{
Configuration cfg = new Configuration().configure();
SessionFactory sf=cfg.buildSessionFactory();
Session ss= sf.openSession();
return ss;
}
catch(Exception ee)
{
System.out.print("失败"+ee.getMessage());
return null;
}
}
//这里调我们在UserVO.hbm.xml
//sql-query 写上的name属性getUser
public void ExampleProc()
{
Session ss=this.getSession();
List li=ss.getNamedQuery("getUser").list();
for(int i=0;i<li.size();i++)
{
UserVO vo=(UserVO)li.get(i);
log.info("name:"+vo.getName());
log.info("age"+vo.getAge());
log.info("address"+vo.getAddress());
}
ss.close();
}
//配置文件的sql查询
public void ExampleSelect()
{
Session ss=this.getSession();
List li= ss.getNamedQuery("select").list();
for(int i=0;i<li.size();i++)
{
UserVO vo=(UserVO)li.get(i);
log.info("name:"+vo.getName());
log.info("age"+vo.getAge());
log.info("address"+vo.getAddress());
}
ss.close();
}
}
记的用最新的驱动:
要不然可能会报这个错

是不是挺简单的。
