需要捕捉并显示堆栈溢出错误消息

我正在从数据库中获取大约17,500条记录，并且正好在结果集执行步骤处获取低于堆栈溢出错误。需要捕捉并显示堆栈溢出错误消息

Query query = dbConnect 
       .createQuery("select nitem from NItem nitem where nitem.id in ("+nitemIdStr+")"); 
     nitemList = query.getResultList();

堆栈溢出流量误差

我需要捕捉这个错误，并在UI有消息说“文件导出超过堆栈限制，请使用过滤条件”，而不是越来越显示它在浏览器中检查流量错误。这可能吗？？？下面

的例子为我工作在testpage：

getRequestCycleListeners().add(new AbstractRequestCycleListener() { 
     @Override 
     public IRequestHandler onException(RequestCycle cycle, Exception e) { 
      return new RenderPageRequestHandler(new PageProvider(SomePage.class)); 
     } 
    });

在你Application添加这一点，它会将您重定向在异常情况下SomePage.class。

但是捕捉堆栈溢出是不好的做法。有很多方法可以防止这种情况，例如限制查询，限制输入大小，跟踪记录处理或跟踪实际堆栈并自行完成。

所以我的建议是防止栈溢出，而不是在检票口捕获它。

我使用了createNativeQuery，它没有给我任何错误。 – user3641156

你可以显示你查询的代码调用吗？它看起来像你有很多基于用户上传的条件。 – Martin

我们能否使用上述方法将错误消息传递给errorpage.class？我用你的代码，它把我带到errorpage.class，但我想扔那边的消息。有没有办法做到这一点？ – user3641156

作为一般规则，捕捉错误不是一个好主意，因为它们通常意味着某些事物处于严重不一致的状态。

捕捉国有企业特别成问题，因为不能保证您能够采取行动。虽然在你的具体情况下，当你捕获它来允许你进一步调用时，堆栈可能会是空的，但你可能触发另一个SOE。

顺便说一句，你必须永远不要做：

Query query = dbConnect 
      .createQuery("select nitem from NItem nitem where nitem.id in ("+nitemIdStr+")");

严重的是，没有。
