java - 无法解析 Maven 项目中的 Spring Security 类

Question

我正在用 Java 编写一个使用 Spring MVC 和 Spring Security 的博客应用程序。我已经配置了 Spring Security，但遇到了一个问题，即我的应用程序无法解析 org.springframework.security 包中的任何类。当我从该包导入任何内容后尝试编译时，出现以下错误:

package org.springframework.security does not exist

现在我正在尝试实现自己的用户服务详细信息类，因此无法导入 UserServiceDetails 接口(interface)。

这是我的 pom.xml(请原谅我的困惑):

pom 是否有任何明显的错误，会导致在 org.springframework.security 包中导入任何内容时出现问题？

我感谢任何人的帮助!

Spring Security 3.2.0 依赖于 Spring Core 3.2.6。您当前运行的是核心版本 3.2.5。

您可以检查 Spring Security 的其他依赖项 here
