java eclipse maven The superclass "javax.servlet.http.HttpServlet" was not found on the Java Build Path 解决方法

在eclipse 中使用maven 创建java web项目，启动服务器遇到提示：The superclass "javax.servlet.http.HttpServlet" was not found on the Java Build Path

一般解决方案：在pom.xml中添加依赖关系：

<dependency>
<groupId>javax.servlet</groupId>
<artifactId>javax.servlet-api</artifactId>
<version>3.0.1</version>
<scope>provided</scope>
</dependency>
