IDEA maven项目创建Web时 JSP如何使用标签

在JSP使用引入

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>红线报错

需要引入依赖：<dependency><groupId>taglibs</groupId><artifactId>standard</artifactId><version>1.1.2</version></dependency><dependency><groupId>jstl</groupId><artifactId>jstl</artifactId><version>1.2</version></dependency><dependency><groupId>javax.servlet</groupId><artifactId>serviceable-api</artifactId><version>3.1.0</version></dependency>IDEA默认是关闭EL表达式的：手动开启：<%@ page ignored="false" %>
