使用maven创建项目时报错The superclass "javax.servlet.http.HttpServlet" was not found on the Java Build Path

 Description Resource Path Location Type

The superclass "javax.servlet.http.HttpServlet" was not found on the Java Build Path index.jsp /ssm-crud/WebRoot line 1 JSP Problem

解决办法如下所示：

在add Library时，没有server runtime，就是用MyEclipse server library

 

然后next->ok。错误就没有了。
