【问题描述】：
这是我第一次使用 Spring，我正在学习 PluralSight 上的教程。运行第一个示例，我遇到了标题中列出的错误。在我的控制台中，我收到这样的错误。我正在使用旧版本的依赖项来完成本课程。我已确保密切关注本教程，因此不确定我是否在某个地方搞砸了或某些东西已被弃用。我正在使用http://localhost:8080/FitnessTracker/greeting.html

【问题讨论】：
-
在您的 servlet-config.xml 中，尝试删除此行 xmlns:p="springframework.org/schema/p" 并检查
-
您需要做的就是确保您的 servlet 容器的运行时是 Java 7。有关详细信息，请参阅my answer。
