什么是将Exception从Servlet重定向到默认错误JSP的正确技巧？ [英] what's the right technique to redirect an Exception from a Servlet to a default error JSP?

问题描述

我需要一个默认的错误JSP页面，当servlet抛出异常时会显示该页面，该页面将显示堆栈跟踪..

如何做我这样做？是否有正确的技术（由API提供）或我必须手动完成？我的意思是，将异常作为属性抛出，然后自己处理它？<​​/ p>

谢谢

解决方案

您可以在web.xml中配置要处理的异常类型和JSP页面，例如：

 <错误页> 
< exception-type> UnhandledException< / exception-type> 
< location> UnhandledException.jsp< / location> 
< / error-page> 
  

这里有关于这个主题的Oracle文章：

I need to have a default error JSP page which is shown when an exception is thrown by the servlet, and that page will show the stacktrace..

How do I do that?? is there a right technique (provided by the API) or I have to do it manually?? I mean, sending the exception thrown as an attribute and then dealing with it by myself??

Thanks

解决方案

You can configure the exception type and the JSP page to handle in web.xml, e.g:

<error-page>
       <exception-type>UnhandledException</exception-type>
       <location>UnhandledException.jsp</location>
</error-page>

There's an Oracle article here on the subject:
