Unexpected exception parsing XML document from ServletContext resource
提问by LoveTW
I find a basic spring security example, but I can't run it usually on tomcat. I know this error message might be caused by the configuration xml file, but I can't find it. Thanks for the help:)
我找到了一个基本的 spring 安全示例，但我通常无法在 tomcat 上运行它。我知道此错误消息可能是由配置 xml 文件引起的，但我找不到它。谢谢您的帮助：）

This is a part of your stacktrace:
这是您的一部分stacktrace：
Constructor threw exception; nested exception is java.lang.NoC
lassDefFoundError: org/springframework/aop/config/AbstractInterceptorDrivenBeanD
efinitionDecorator
which says that Aspect Oriented Programming (AOP) Frameworkjars are not present in the classpath. So you need to add spring-aop(spring-aop-3.0.5.RELEASE.jar) jars to your classpath.
这表示Aspect Oriented Programming (AOP) Framework.jar 文件中不存在 jars classpath。所以你需要将spring-aop(spring-aop-3.0.5.RELEASE.jar) jars 添加到你的classpath.

You need to add spring.jar to your library. spring-security jars would be referencing it. Hence failing initialization.
您需要将 spring.jar 添加到您的库中。spring-security jars 将引用它。因此初始化失败。

I found same exception in my project but after adding spring-aop-4.1.6.RELEASE.jar i resolved the problem. please be careful about the version of jar which you are going to add in your project... :)
我在我的项目中发现了同样的异常，但是在添加 spring-aop-4.1.6.RELEASE.jar 之后我解决了这个问题。请注意您要添加到项目中的 jar 版本... :)
