快速浏览一下代码..

我无法看到在哪里/谁加载Application-context.xml，因此显然你没有得到你的hibernate SessionFactory，数据源等。

我只能在web.xml上看到您正在通过DispatcherServlet加载app-config.xml

在加载Application-context.xml的web.xml上使用Spring监听器：

<listener>
  <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
