2、没有jstl架包。下载jstl架包，引入；如果是maven项目引入
<!-- https://mvnrepository.com/artifact/javax.servlet.jsp.jstl/jstl -->
<dependency>
<groupId>javax.servlet.jsp.jstl</groupId>
<artifactId>jstl</artifactId>
<version>1.2</version>
</dependency>
3、jsp也买你引入
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
4、就可以使用jstl标签了。
<c:set var="ctx" value="${pageContext.request.contextPath}" scope = "request"/>
