SSH框架里用SQL查出的Object对象不能转化为映射类是为什么啊
User表和Department两张表 是多对一的关系，Department的主键是User的外键

SSH框架中hibernate的配置文件如下
<hibernate-mapping>
   <class name="com.pmsystem.model.authority.Department" table="t_department">
  <id name="dptId">
     <generator class="native"/>
  </id>
  
  <property name="dptName">
     <column name="dptName" not-null="true" />
  </property>
   </class>
</hibernate-mapping>

<hibernate-mapping>
   <class name="com.pmsystem.model.authority.User" table="t_user">
  <id name="userId">
     <generator class="native"/>
  </id>
  <property name="loginName">
     <column name="loginName" not-null="true" />
  </property>
  <property name="password">
     <column name="password" not-null="true" />
  </property>
  <property name="userName">
     <column name="userName" not-null="true" />   
  </property>
 
      <many-to-one name="Department" class="com.pmsystem.model.authority.Department" column="dptId" cascade="save-update"></many-to-one>      
   </class>
</hibernate-mapping>








public List<User> getLoginUser(final User user) {

//查询登陆的sql语句必须是fianl类型的


final String loginSql = "select * from t_user u where u.loginName = ? and u.password = ?";

List<User> result = this.getHibernateTemplate().executeFind(new HibernateCallback(){

public List<User> doInHibernate(Session session) throws HibernateException, SQLException {

SQLQuery query = session.createSQLQuery(loginSql);

query.setString(0, user.getLoginName()); 
                                query.setString(1, user.getPassword());
                
                               //获得结果
                               List<Object> temp = (List)query.list();
                               List<User> t = (List)temp ;
