Question

我有这个hbm文件只是为了测试/练习如何在xml文件中使用命名的sql，但它给了我“命名查询未知：testQuery1”

    public List<Meb_item> namedList() {
    // TODO Auto-generated method stub
    Session session = sessionFactory.getCurrentSession();
    return session.getNamedQuery("testQuery1").list();
}

<hibernate-mapping>
 <class table="SIDEEFFECT.MEB_ITEM"  name="foreign.Meb_item"> 
  <id name="meddev_item_seq">
   <column name="MEDDEV_ITEM_SEQ"/>
  </id>

  <resultset name="testRs">
    <return   class="foreign.Meb_item">
        <return-property name="item_name" column="item_name"></return-property>
    </return>     
  </resultset>

  <sql-query name="testQuery1" callable="true" >
        select * from meb_item     
    <return   class="foreign.Meb_item" >
        <return-property name="item_name" column="item_name"></return-property>
    </return>    
  </sql-query> 
</class>

这是我的hibernate.cfg.xml的一部分

<hibernate-configuration>
    <session-factory>
      <mapping resource="mea_class_no.hbm.xml"/>
      <mapping resource="mea_compay.hbm.xml"/>
      <mapping resource="meb_item.hbm.xml"/>
    </session-factory>
</hibernate-configuration>

我已经查阅了JBoss文档，但我找不到有什么问题。为什么说命名查询不知道？

Answer 1

我明白了。
sql-query标记似乎对映射文档中的位置敏感。
我把它从类标签的内部移到了它的外面现在似乎按预期调用了。虽然它提示另一个错误。
这是整个映射文件。

我希望它有所帮助：）
