当我尝试将 Spring Security 引入我的代码时，出现此错误。 Spring版本是4.3.18，Spring Security版本是3.2.7。
错误如下:

我似乎不明白问题是什么。在添加 Spring Security 之前，它似乎工作正常，但这可能是无关的。请帮我弄清楚如何解决这个问题。
最佳答案
查看您使用的版本，您的 Spring-Core 版本来自 2018 年 6 月。 Spring-Core Versions
您的 Spring-Security 版本来自 2014 年 1 月。 Spring-Security Versions
您的 Spring security 版本期望 Spring-Core 中存在某些方法，但它们在 2018 版本的 Spring 中不再存在。
我建议您将Spring-Security的版本升级到4.2.6.RELEASE附近的版本来解决您的问题。
