获取一些堆栈跟踪信息到自定义的Tomcat错误500页面 [英] get some stack trace info into a custom tomcat error 500 page

问题描述

用tomcat，spring，jsf将一些堆栈跟踪信息(也许是Exeception.message)放到我的自定义错误500页面上的最佳方法是什么?我只想显示出受害的根本原因.

What is the best way of getting some of the stack trace info, perhaps the Exeception.message onto my custom error 500 page with tomcat, spring, jsf? I'd just like the root cause of the exeception displayed.

推荐答案

这是我在Struts中使用的JSP语法.您可能可以使用JSf获得此功能或类似功能.

Here's the JSP syntax, which I have used with Struts. You can probably get this or similar working with JSf.

<!-- Get the exception object -->
<c:set var="exception" value="${requestScope['javax.servlet.error.exception']}"/>

<!-- Exception message(s) -->
<p>${exception.message}</p>
<p><c:if test="${not empty exception.cause.message}">${exception.cause.message}</c:if></p>

<!-- Stack trace -->
<jsp:scriptlet>
exception.printStackTrace(new java.io.PrintWriter(out));
</jsp:scriptlet>
