Eclipse Maven项目出现“The superclass "javax.servlet.http.HttpServlet" was not found on the Java Build Path”
Eclipse 新建完Maven项目后在index.jsp里出现“The superclass "javax.servlet.http.HttpServlet" was not found on the Java Build Path”的错误提示，大概意思是没找到javax.servlet.http.HttpServlet？这个父类？
解决：右键项目 Build Path --> Configure Build Path 接着看图下操作
最后apply close
