hibernate 调用存储过程

笔者参考原文：http://www.iteye.com/topic/176032

使用hibernate 调用存储过程。

public class StuInfo {
	private int id;
	private String stuName;
	private String stuNo;
	private int stuAge;
	private String stuId;
	private String stuSeat;
	private String stuAddress;

setters();getters();

}

对应的数据库表：

if exists(select * from sysobjects where name='stuInfo')
drop table stuInfo
create table stuInfo /*创建学员信息表**/
(
 stuName varchar(20) not null,-- 姓名，非空
 stuNo char(6) not null,-- 学号，非空
 stuAge int not null,-- 年齡，int 默认为4个长度
 stuId numeric(18,0),
 stuSeat smallint ,-- 坐位车，使用自增
 stuAddress text -- 住址 可以为空
)
-- 给stuInfo添加一列
alter table stuInfo add id int identity(1,1) primary key;

创建存储过程：

-- 存储过程
if exists(select name from sysobjects where name='proc_stuInfo' and type='p')
drop proc proc_stuInfo
go
create proc proc_stuInfo
as
 select * from stuInfo
go
-- 调用存储过程
exec proc_stuInfo;

在hibernate 中调用存储过程的几种方法。

第一种：命名查询

  <sql-query name="getStuInfo" callable="true">  
     <return alias="stuInfo" class="com.hkrt.domain.StuInfo">  
        <return-property name="id" column="id" />  
		<return-property name="stuName" column="stuName" />
		<return-property name="stuAge" column="stuAge" />
		<return-property name="stuNo" column="stuNo"/>
		<return-property name="stuSeat" column="stuSeat" />
		<return-property name="stuAddress" column="stuAddress"/>
		<return-property name="stuId" column="stuId"/>
     </return>  
     {call proc_stuInfo()}  
  </sql-query> 

	List li=session.getNamedQuery("getStuInfo").list();  
		System.out.println(li.get(0));

第二种：类型于jdbc

	System.out.println("jdbc 调用-------------");
		Connection conn = session.connection();   
		ResultSet rs =null;  
		CallableStatement call;
		try {
			call = conn.prepareCall("{Call proc_stuInfo()}");
			rs = call.executeQuery(); 
		   	while(rs.next()){
		   		System.out.println(rs.getString(1));
		   		System.out.println(rs.getString(2));
		   		System.out.println(rs.getString(3));
		   		System.out.println(rs.getString(4));
		   		System.out.println(rs.getString(5));
		   		System.out.println(rs.getString(6));
		 		System.out.println(rs.getString(7));
		   		System.out.println("------------------");
		   	}
		} catch (SQLException e) {
			e.printStackTrace();
		}  

第三种：最简单的一种

	SQLQuery query =  session.createSQLQuery("{call proc_stuInfo()}").addEntity(StuInfo.class);  
	List list =query.list(); 
	System.out.println(list.get(0));

注：在第三种调用时，一定要加上addEntity();否则没有数据返回。

hibenate 调用带参的存储程

-- 带参数据的存储过程
if exists(select name from sysobjects where name='proc_find_stu' and type='p')
drop proc  proc_find_stu
go
create proc  proc_find_stu(@startId int,@endId int)
as
 select * from stuInfo where id between @startId and @endId;
go
exec proc_find_stu 1,4;

	/**hibernate 调用带参的存储过程*/
	@SuppressWarnings("unchecked")
	@Test
	public void msTest2(){
		SessionFactory sf = SessionFactoyUtil.getSessionFactory();
		Session session = sf.openSession();
		SQLQuery query =   session.createSQLQuery("{CALL proc_find_stu(?,?)}").addEntity(StuInfo.class);
		query.setLong(0, 2);  
		query.setLong(1, 4);  
		List<StuInfo> list =query.list(); 
		 for(int i =0;i<list.size();i++){
			 System.out.println(list.get(i));
		 }
	}

结果信息：

Hibernate: 
    {CALL proc_find_stu(?,?)}
StuInfo [id=2, stuAddress=北京, stuAge=12, stuId=123456789012345687, stuName=李四, stuNo=112345, stuSeat=2]
StuInfo [id=4, stuAddress=北京, stuAge=12, stuId=123456789012345688, stuName=王五, stuNo=112345, stuSeat=3]
