如何使用Debbuger添加监视表达式功能在Eclipse中监视NullPointerEx? [英] How to watch for NullPointerEx in Eclipse using Debbuger Add Watch Expression feature?

问题描述

我该如何使用Eclipse的添加监视表达式来监视我的应用程序可以抛出的任何 NullPointerException ?

Hi how can I use that Add Watch Expression of eclipse to watch for any NullPointerExceptions that my application can throw ?

我看到Guy曾经向该功能添加一些代码，并且他使Eclipse调试器在NullpointerEx诞生时停止运行.

I saw a Guy once adding some code into that feature and with that he made eclipse debugger to stop when any NullpointerEx was "born".

我想学习如何做.

推荐答案

您不使用监视表达式".转到断点"视图，并为 NullPointerException 添加一个异常断点.

You don't use 'watch expression'. Go to the "breakpoints" view and add an exception breakpoint for NullPointerException.
