Hibernate查询异常

我有一个Hibernate查询我试图让工作，但不断收到异常与一个不那么有用的堆栈跟踪。在引发异常之前，我包含了代码，堆栈跟踪和hibernate聊天记录。如果您需要我包含MessageTarget和GrpExclusion的实体类，请在评论中告知我，然后添加它们。Hibernate查询异常

public List<MessageTarget> findMessageTargets(int age, String gender, String businessCode, String groupId, String systemCode) { 
    Session session = getHibernateTemplate().getSessionFactory().openSession(); 
    List<MessageTarget> results = new ArrayList<MessageTarget>(); 
    try { 
     String hSql = "from MessageTarget mt where " + 
         "not exists (select GrpExclusion where grp_no = ?) and " + 
         "(trgt_gndr_cd = 'A' or trgt_gndr_cd = ?) and " + 
         "sys_src_cd = ? and " + 
         "bampi_busn_sgmnt_cd = ? and " + 
         "trgt_low_age <= ? and " + 
         "trgt_high_age >= ? and " + 
         "(effectiveDate is null or effectiveDate <= ?) and " + 
         "(termDate is null or termDate >= ?)"; 

     results = session.createQuery(hSql) 
             .setParameter(0, groupId) 
             .setParameter(1, gender) 
             .setParameter(2, systemCode) 
             .setParameter(3, businessCode) 
             .setParameter(4, age) 
             .setParameter(5, age) 
             .setParameter(6, new Date()) 
             .setParameter(7, new Date()) 
             .list(); 
    } catch (Exception e) { 
     System.err.println(e.getMessage()); 
     e.printStackTrace(); 

    } finally { 
     session.close(); 
    } 
    return results; 
}

这是堆栈跟踪。

你没有正确编写你的HQL。我建议阅读文档中的HQL chapter。

有几件事情我看错了与查询：

  1. 你再选择是不是一个有效的HQL查询。类似于（来自GroupExclusion ge，其中groupNumber =？）可能更接近你想要的。
  2. 列名应与他们的Java的getter的名字，而不是数据库列名。

  3. 应关闭HibernateSession在finally块：。

    会话的会话= getHibernateTemplate（）了getSessionFactory（）的openSession（）; 尝试{ ... } {终于 session.close（）; }

是的，我一直在阅读HQL文档，以获得一些帮助写这篇文章。本周我刚开始使用Hibernate，所以我正在学习这条曲线。我之前写过SQL和JPQL ......所以我并没有完全不用它。谢谢！ – dharga 2010-05-06 19:36:54
