Maven项目启动报错:The absolute uri: http://java.sun.com/jsp/jstl/core cannot be resolved in either web.xml

一、问题描述

Eclipse创建Maven项目修改web.xml版本号为3.0

<?xml version="1.0" encoding="UTF-8"?>
<web-app
version="3.0"
xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"> <display-name>Elasticserach</display-name>
</web-app>
然后在POM.XML中加入JSTL1.2

<!-- JSTL -->
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>jstl</artifactId>
<version>1.2</version>
</dependency>

在index.jsp页面加入c标签

<%@ page language="java" contentType="text/html; charset=utf-8"
pageEncoding="utf-8"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
一运行项目就提示错误如下: 

HTTP Status 500 - The absolute uri: http://java.sun.com/jsp/jstl/core cannot be resolved in either web.xml or the jar files deployed with this application

二、解决方法

解决方法就是复制jstl到tomcat/lib目录下就行了!!!
