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'?>
<! DOCTYPE

<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>
</ -mapping>
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。
