通过hibernate去调用存储过程

Java代码

CREATE TABLE `proctab` (

`id` int ( 11 ) NOT NULL auto_increment,
`Name` varchar ( 20 ),
`age` int ( 11 ),
PRIMARY KEY (`id`)
)

CREATE   TABLE  `proctab` (
`id`  int ( 11 )  NOT   NULL  auto_increment,
`Name`  varchar ( 20 ),
`age`  int ( 11 ),
PRIMARY   KEY   (`id`)
)

create PROCEDURE proc()

begin
select * from proctab;
end ;

create   PROCEDURE  proc()
begin
select   *   from  proctab;
end ;

一种方法是通过hibernate传统的xml映射方式去调用

Java代码
<class name="com.test.User" table="proctab">

<id name="id" column="id">
<generator class="native"/>
</id>
<property name="name" column="name" type="string" />
<property name="age" column="age" type="integer" />
</class>
<sql-query name="getUser" callable="true">
<return alias="user" class="com.test.User">
<return-property name="id" column="id" />
<return-property name="name" column="name" />
<return-property name="age" column="age" />
</return>
{call proc()}
</sql-query>

<class name="com.test.User" table="proctab">
<id name="id" column="id">
<generator class="native"/>
</id>
<property name="name" column="name" type="string" />
<property name="age" column="age" type="integer" />
</class>
<sql-query name="getUser" callable="true">
<return alias="user" class="com.test.User">
<return-property name="id" column="id" />
<return-property name="name" column="name" />
<return-property name="age" column="age" />
</return>
{call proc()}
</sql-query>

调用方法

Java代码

Session ss= HibernateSessionFactory.getSession()
List li=ss.getNamedQuery("getUser").list();
ss.close();

Session ss= HibernateSessionFactory.getSession()
List li=ss.getNamedQuery("getUser").list();
ss.close();

及其类似jdbc的方法

Java代码
Session session =HibernateSessionFactory.getSession();

Connection conn = session.connection();
ResultSet rs =null;
CallableStatement call = conn.prepareCall("{Call proc()}");
rs = call.executeQuery();
rs.close();
session.close();

Session session =HibernateSessionFactory.getSession();
Connection conn = session.connection();
ResultSet rs =null;
CallableStatement call = conn.prepareCall("{Call proc()}");
rs = call.executeQuery();
rs.close();
session.close();

这种方法基本上就是jdbc，不过很简单，总是感觉怪怪的~！

还有就是通过强大的createSQLQuery来实现

o(∩_∩)o...哈哈 个人比较喜欢这种方法

Java代码

Session session =HibernateSessionFactory.getSession();

SQLQuery query = session.createSQLQuery("{Call proc()}");
List list =query.list();
session.close();

Session session =HibernateSessionFactory.getSession();
SQLQuery query = session.createSQLQuery("{Call proc()}");
List list =query.list();
session.close();

如果没有返回值 直接用execute的方法就可以了

(*^__^*) 忘了一个重要的问题就是存储过程的传参问题

Java代码

CallableStatement call = conn.prepareCall("{Call proc(?)}");

call.setString(1, 参数);
rs = call.executeQuery();

CallableStatement call = conn.prepareCall("{Call proc(?)}");
call.setString(1, 参数);
rs = call.executeQuery();

Java代码

SQLQuery query = session.createSQLQuery("{Call proc(?)}");

query.setString(0, 参数);
List list =query.list();

SQLQuery query = session.createSQLQuery("{Call proc(?)}");
query.setString(0, 参数);
List list =query.list();
