Hibernate深入浅出（二）MySQL存储过程

创建存储过程：

mysql> DELIMITER //
mysql> CREATE PROCEDURE getUsersByAge(IN userAge int)
    -> BEGIN
    -> SELECT ID,NAME,AGE FROM T_USER WHERE AGE=userAge;
    -> END
    -> //
Query OK, 0 rows affected(0.10 sec)

 映射文件配置：

和class同级的节点sql-query

<sql-query name="queryUsersByAge" callable="true" >
    <return
        alias="user"
        class="com.redsaga.hibernate.relation.TUser">
        <return-property name="id" column="ID"/>
        <return-property name="name" column="NAME"/>
        <return-property name="age" column="AGE"/>
    </return>
    { call getUsersByAge(?) }
</sql-query>

{ call getUsersByAge(?) } 调用存储过程

callable=”true”，指名当前查询基于存储过程定义

测试代码：

public void testProcedure() {
        Query query = session.getNamedQuery("queryUsersByAge");
        query.setParameter(0, 20);

        Iterator it=query.list().iterator();
        while(it.hasNext()){
            TUser user=(TUser)it.next();
            System.out.println("User Name=>"+user.getName());
        }
    }
