我正在开发Spring MVC，Spring Security示例，在开发此代码时，我遇到以下错误：花了很多天后，我仍然无法解决此错误。请尽快指导我。

看起来spring-webmvc所需的缺少的类可以从spring-core 4.2.3版（https://docs.spring.io/spring/docs/current/javadoc-api/org/springframework/core/MethodIntrospector.html）开始使用，但是你使用的是4.2.2。 尝试添加版本4.2.3的spring-core的显式版本或尝试更新版本的spring-security-web 4.0.4.RELEASE。此版本在版本4.2.5中使用spring-core。
