Spring MVC servlet没有初始化

Question

我在我的Kepler Eclipse中配置了tomcat 7。截至目前，我已向此服务器添加了三个应用程序。在三个服务器中，两个应用程序的servlet正在初始化，而剩下的一个应用程序在初始化时面临问题，并且在浏览器上遇到此应用程序的请求时，我得到404资源未找到异常。

以下是正在服务器中添加的应用程序的屏幕截图 -

如上所示，MVC_CRUD_SPRING应用程序未被服务器初始化。

以下是服务器启动时的控制台日志 -

如果检查上面的日志，则不会看到位于MVC_CRUD_SPRING应用程序中的任何Employee-servlet初始化日志。

检查server.xml上下文条目 -

<Context docBase="HelloSpringMVCForm" path="/HelloSpringMVCForm" reloadable="true" source="org.eclipse.jst.jee.server:HelloSpringMVCForm"/>
<Context docBase="MVC_CRUD_SPRING" path="/MVC_CRUD_SPRING" reloadable="true" source="org.eclipse.jst.jee.server:MVC_CRUD_SPRING"/>
<Context docBase="HelloWeb" path="/HelloWeb" reloadable="true" source="org.eclipse.jst.jee.server:HelloWeb"/>

MVC_CRUD_SPRING的web.xml如下：

对此的任何帮助都将受到高度赞赏。
