ClassNotFound：在Servlet类中使用它时的ClassPathXmlApplicationContext

Question

我想在应用程序中一起使用Spring和Servlet。

出于相同的目的，我编写了以下代码：

@WebServlet("/SaveServlet")
public class SaveServlet extends HttpServlet {
    private static final long serialVersionUID = 1L;

    protected void doPost(HttpServletRequest request, HttpServletResponse response)
            throws ServletException, IOException {

        ClassPathXmlApplicationContext ctx = new ClassPathXmlApplicationContext("E:\\SouceTree\\JavaEE\\Servlets\\CRUDServlet\\resources\\spring.xml");
}
}

当我按URL http://localhost:8080/CRUDServlet/SaveServlet部署应用程序后， 它会引发以下异常堆栈：

有人可以帮我吗？
