我有一个hibernate查询我正在努力工作，但是继续得到一个不太有用的堆栈跟踪异常。在抛出异常之前，我包括代码，堆栈跟踪和休眠聊天。如果你需要我为MessageTarget和GrpExclusion包含实体类，请在评论中告诉我，我会添加它们。
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。

答案 0 :(得分：2)
您没有正确编写HQL。我建议您阅读文档中的HQL chapter。
我的查询有一些错误：
您应该在finally块中关闭HibernateSession：
Session session = getHibernateTemplate（）。getSessionFactory（）。openSession（）; 尝试{ ... } finally { session.close（）; }
