準備工作:
1.hibernate3
到這下載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和最新驅動)
?mysql官方網站
http://www.mysql.com/
1.建張表
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;
插入幾條記錄
INSERT?INTO?`proctest`?VALUES?(1,'tom',22,'http://m.tkk7.com');
INSERT?INTO?`proctest`?VALUES?(2,'wujun',25,'http://m.tkk7.com/wujun');
INSERT?INTO?`proctest`?VALUES?(3,'jerry',30,'深圳');
INSERT?INTO?`proctest`?VALUES?(4,'wujun',40,'南昌');
創建存儲過程
--這只是一個例子,就來個簡單存儲過程
create?PROCEDURE?testProc()
begin
???select?*?from?proctest;
end;
打開eclipce新建個java工程,記的把hiberbate3類庫也一起加進去..
看下結構圖:
1.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()
????{} 順便把它相對應的配置文件也寫上。。
UserVO.hbm.xml?
<?xml?version="1.0"?encoding='UTF-8'?>

?????</return>
?????<!--這里就是我們剛剛創建的存儲過程名-->
?????{call?testProc()}
?????</sql-query>
</hibernate-mapping>
測試代碼
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("失敗"+ee.getMessage());
????????????return?null;
????????}
??????
????}
????//這里調我們在UserVO.hbm.xml
????//sql-query?寫上的name屬性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查詢
????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();??
????}
} 記的用最新的驅動:
要不然可能會報這個錯

源代碼
http://m.tkk7.com/Files/wujun/Proc.rar是不是挺簡單的.
