我现在一般来说是 Spring、GAE 和 Java。我正在尝试使用我为 Spring 制作的 Web 应用程序，之后我添加了 GAE 支持。我经历了很多问题，但现在我被困在这个问题上。

我意识到我的上下文没有正确初始化，但由于这是由 Spring 直接管理的，我不知道如何解决这个问题。我不确定我应该给你什么信息，所以这里有一些重要的文件。

从我在这里看到的配置文件中。一切看起来都很好。异常表示初始化错误，有时会发生在属性文件或构造函数无法初始化的情况下。你能根据这里的配置文件验证一下吗？

<resources mapping="/resources/**" location="/resources/" />

已配置并准备就绪？？我在 src 下有我的属性文件夹，它被编译到输出目录。

堆栈跟踪中的另一件事是 DefaultListableBeanFactory 异常初始化问题。请验证您的类路径中是否有正确版本的 spring Jar 文件。
