Answer 1

现在问题解决了，我在eclipse底部面板的标记选项卡上有一些问题需要解决，主要问题是：

Cannot change version of project facet Dynamic Web Module to 3.0 

解决方案是更新web.xml的头：

<web-app xmlns="http://java.sun.com/xml/ns/javaee"
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
     xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
      http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
version="3.0">
<display-name>Servlet 3.0 Web Application</display-name>
</web-app> 

然后只需maven->Update Project..
