Java 在使用MS SQL 2008的Hibernate 4期间，如何修复setResultTransformer方法中的异常？

如何在休眠期间修复setResultTransformer方法中的异常

我有一个调用命名查询的方法

SessionFactory sf =  HibernateUtil.createSessionFactory();
        Session session = sf.openSession();
        Transaction t = session.beginTransaction();
        Query  qr = session.getNamedQuery("Product_Create");
        qr.setParameter("@Return", 0); 
        qr.setParameter("@ProdIDID", 0);
        qr.setParameter("@PassID", new BigInteger("9999999999"));
        qr.setParameter("@Amount", new BigInteger("7777777777"));

        t.commit();
        List<CreatedCardBean> list = qr.setResultTransformer(Transformers.aliasToBean(CreatedCardBean.class)).list(); 
        for(int i=0; i<list.size(); i++){
            CreatedCardBean card = (CreatedCardBean)list.get(i);
            LOG.info(String.valueOf(card.getCardId()));
        }

我的hibernate配置如下所示：

    <hibernate-configuration>
  <session-factory>
    <property name="connection.driver_class">com.microsoft.sqlserver.jdbc.SQLServerDriver</property>
    <property name="connection.url">jdbc:sqlserver://....</property>
    <property name="connection.username">user</property>
    <property name="connection.password">pass</property>
    <property name="connection.pool_size">10</property>
    <property name="dialect">org.hibernate.dialect.SQLServerDialect</property>
    <property name="show_sql">true</property>
    <property name="hibernate.connection.autocommit">true</property>
    <!--<property name="current_session_context_class">thread</property> -->

    <mapping resource="com/comp/common/Product_Create.hbm.xml"></mapping>

  </session-factory>
</hibernate-configuration>  

有人能帮我解决这个异常吗

更新 CreatedCardBean是：

public class CreatedCardBean {
        private int ReturnValue;
        private long prodID;

        public int getReturnValue() {
            return ReturnValue;
        }
        public void setReturnValue(int returnValue) {
            ReturnValue = returnValue;
        }
        public long getProdID() {
            return prodID;
        }
        public void setProdID(long prodID) {
            this.prodID = prodID;
        }
}

可能是

存储过程引发了一些异常

在执行查询后尝试关闭事务。transacrion classt中没有close方法。我添加了session.close（），但问题仍然存在。存储过程毫无例外地工作。我的代码似乎无法捕获输出参数并将其放入CreatedCardBean。仍然需要帮助。可能是
