Jsp页面报错The superclass "javax.servlet.http.HttpServlet" was not found on the Java

Eclipse创建jsp后报错Multiple annotations found at this line:- The superclass “javax.servlet.http.HttpServlet” was not found on the JavaBuild Path- The superclass “javax.servlet.http.HttpServlet” was not found on the JavaBuild Path

这里写图片描述

是因为缺少servlet-api.jar右击项目文件，选择Build Path–>Configure Build Path…–>Libraries如果没有Apache Tomcat，就点击Add Library–>Server Runtime–>Next–>选择Apache–>Finish，刷新项目看看错误是否消失。

如果有Apache Tomcat就点击Add Library…–>Server Runtime–>Next–>点击Apache tomcat->Finish–>ok，
