NestedServletException的起源是什么? [英] What is the origin of a NestedServletException?

问题描述

最近我一直在使用Hybris平台，今天在Tomcat中遇到了一个异常.问题是我似乎找不到有关NestedServletException是什么或引发原因的任何有价值的信息.目前，我的首要任务是理解概念，然后解决它.

Lately I've been working with the Hybris platform and I encountered an exception in my Tomcat today. The issue is I can't seem to find any valuable information about what a NestedServletException is or why it's thrown. At the moment my priority is to understand the concept, then after solve it.

如果有用，我将附加StackTrace:

In case it's usefull, I'll attach the StackTrace:

推荐答案

嵌套异常是包裹在另一个异常中的异常.人们这样做是出于多种原因(其中有些人在此处中提到).

Nested Exceptions are exceptions wrapped up in another exception. People do that for multiple reasons (some of them mentioned here).

您可以在堆栈跟踪中看到root exception是nullpointer exception.

As you can see in the stack trace the root exception is a nullpointer exception.

因此，基本上，您的NestedServletException只是被捕获的& ;;的NullpointerException.再次抛出，但包裹在ServletException中.

So basically your NestedServletException is nothing but a NullpointerException that is caught & thrown again at some point, but wrapped up in a ServletException.
