我正在开发一个使用 Hibernate 作为持久性提供程序的 SpringData/JPA2 Web 服务。它使用以下框架：
cxf=2.6.2
hibernate= 4.1.1.Final
springframework=3.1.2.RELEASE
spring.data=1.2.0.RELEASE
与数据库相关的代码位于“核心子模块”中，在 Eclipse 进行单元测试时可以正常工作。我有另一个 webservice 子模块，它具有 core-submodule 作为依赖项。到目前为止，当我从 Eclipse 进行单元测试时，它似乎在开发过程中运行良好。现在，我已经取得了足够的进展，我正在尝试将它部署到我桌面上新安装的 jboss AS 7.2 中。我已经在standalone.xml 中设置了数据源，并且还在modules 目录中部署了jTDS 1.2.7 的驱动程序。
当我部署我的战争文件时，我得到了这个错误堆栈跟踪。我不知道从哪里开始解决这个错误。因此，任何提示或要点都值得赞赏，因为我不知道从哪里开始：（堆栈跟踪粘贴在下面：

基本上，当它试图实例化存储库时，它看起来好像正在获取一个空指针。
这是 web.xml。我应该使用 CXFServlet 吗？或者这看起来足够了吗？

此外，可能不相关，但很高兴知道。在其中，我看到了一条警告消息：
JBAS016012: Deployment deployment "euclid-ws.war" contains CDI annotations but beans.xml was not found.
尽管我没有尝试显式使用 CDI，但我是否应该在 WEB-INF 中有一个空的 beans.xml 文件？或者我可以在尝试使用 Spring Container 时安全地忽略警告吗？
