所以我正在努力学习jsf、maven、spring和hibernate。我最近有一个 web 项目从 ui 中获取数据，将其传递给托管 bean、域对象，然后保存到 db。但现在我想更好地构建事物并拥有两个独立的项目。一个用于我的 ui 和托管 bean（这是我的 webapp 项目）。另一个用于我的域和业务逻辑（这是一个普通的 java 项目）。我有两个应用程序上下文文件（web-applicationContext.xml 和 core-applicationContext.xml）。我的 web-applicationContext 在服务器启动期间被拉出，我正在尝试将 core-applicationContext 导入我的 web。但是当我启动我的服务器并尝试访问该站点时，我得到了这个......

我想core-applicationContext.xml没有导入，因为导入语句是错误的。尝试

<import resource="classpath:/resources/core-applicationContext.xml" />

或者

<import resource="classpath:core-applicationContext.xml" />

我不确定您的项目是如何组织的。请参阅编写基于 XML 的配置元数据以供参考。

此外，如果您在其中声明的 bean 中放置一个断点，core-applicationContext.xml您将看到 Spring 是否实例化它们。
