1. maven pom 添加依赖
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>jstl</artifactId>
<version>1.2</version>
</dependency>
检查依赖正常
2. jsp 添加 taglib 指令
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
添加指令的时候ide没有抛错并且会自动提示。
3. 但是在启动服务的抛出异常
org.apache.catalina.core.StandardWrapperValve.invoke Servlet.service() for servlet [jsp] in context with path [] threw exception [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] with root cause

查询过解决办法
将 apache 的 standard.jar 包导入
将 jstl.jar 和 standard.jar copy 到 web-inf/lib 目录下
还有说 jstl1.2 不需要standard.jar
还有确定 taglib 的 uri 是 http://java.sun.com/jsp/jstl/...
上面的四种方法我都试过，并且都失败了。
有哪位同学或前辈知道原理的麻烦解释下，或者告知一下解决办法。不胜感激。。。
我的 ide 是 ideaJ
