log4j中的异常深度

问题描述

我的Myfaces 2应用程序出现实例化异常.但是通过log4j进行的异常打印将中断其余的堆栈跟踪.这是我所看到的:

Im getting in instantiation exception inf our Myfaces 2 application. But the exception printing through log4j is cutting off the rest of the stacktrace. Here is what I am seeing:

我找不到更改配置的位置，因此可以看到"... 48个以上".有什么想法吗?

I cannot find where to change the config so I can see the "... 48 more". Any ideas?

推荐答案

您不能.堆栈跟踪的截断是JVM的功能，而不是log4j的功能.

You cannot. The truncation of the stack trace is a feature of the JVM, not log4j.

它实际上只是丢弃已经提供给您的信息.... 48 more是the 48 frames that preceded the "Caused by" message的简写.因此，在您的情况下，省略的48帧是:

It's actually only discarding information that it has already presented to you.The ... 48 more is a shorthand for the 48 frames that preceded the "Caused by" message. So, in your case, the elided 48 frames are:
