Hibernate 错误 : current transaction is aborted, 命令被忽略，直到事务 block 结束

Question

我在 catalina.out 日志中随机看到相同的错误:

我不知道这个问题的原因是什么，因为我随机得到它并且通常查询工作正常。 m 使用 Postgresql 8.3，应用程序在 JSF 2.0 中。有没有人处理过这样的错误？是什么原因？感谢您的任何建议。

我需要补充一点，我只是从数据库中读取数据，但不会在这些查询中更新或插入任何数据。

--------------------------------编辑------------ --------------------------这是一个示例查询:

List object = null; 
try { 
org.hibernate.Transaction tx = session.beginTransaction(); 
Query q = session.createQuery("from Table where lower(translatedText) like lower('%" + term + "%') or lower(translatedAscii) like lower('%" + term + "%') or lower(originalAscii) like lower('%" + term + "%')"); 
object = (List<Table>) q.list(); 
} catch (Exception e) 
{ e.printStackTrace(); } 
return object; }

我刚刚在 tomcat 日志中注意到了这一点:

Initial SessionFactory creation failed.java.lang.OutOfMemoryError: PermGen space

会不会是这个原因？如果我刷新应用程序，它往往会正常工作一段时间。

最好的问候，萨斯。

Answer 1

这可能意味着您的某些查询未执行。如果您在交易中有很多查询，例如

• 开始交易
• 查询1
• 查询2
• 查询3
• 完成交易

并且 query2 抛出错误，然后当您尝试执行 query3 时，您会收到此错误。

• 开始交易
• 查询 1(成功)
• query2(错误，出了点问题)
• query3(抛出类似你的异常)
• 完成交易

您应该处理从 query2 抛出的异常并处理它。向用户显示一些错误，回滚事务，永远不要尝试执行 query3。

另请参阅此处:http://www.faqs.org/docs/ppbook/x15040.htm

更新

完成交易:

List object = null; 
try {
  org.hibernate.Transaction tx = session.beginTransaction(); 
  try { 
    Query q = session.createQuery("from Table where lower(translatedText) like lower('%" + term + "%') or lower(translatedAscii) like lower('%" + term + "%') or lower(originalAscii) like lower('%" + term + "%')"); 
    object = (List<Table>) q.list(); 
  } catch (Exception e) {
    e.printStackTrace(); 
  } finally {
    //You can safely rollback here because you are not changing anything in the DB.
    //If you change something, you should commit transaction at the end of try block,
    //and here check if it is still active and rollback if it is.
    tx.rollback();
  }
  return object; 
} catch (HibernateException e) {
  throw new RuntimeException("Could not begin transaction");
}
