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>
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" %>
就可以使用jstl标签了。 <c:set var="ctx" value="${pageContext.request.contextPath}" scope = "request"/>
