java.lang.ClassNotFoundException: javax.el.E​​LResolver Spring Web MVC with Hibernate error

问题描述

我收到的错误：-

org.apache.catalina.core.Applicationdispatcher invoke
SEVERE: Servlet.service() for servlet [jsp] threw exception
java.lang.classNotFoundException: javax.el.ELResolver

我是使用休眠的 Spring Web MVC 的新手，我正在尝试使用 JSTL 核心标签显示从数据库获取的记录，但出现此错误，我尝试手动添加外部 jar，我尝试添加 jar 作为依赖项，我重新安装了 tomcat并尝试了不同的版本，我基本上在stackoverflow上尝试了与此问题相关的所有可用解决方案，我尝试了stackoverflow和其他站点上提到的大约20个解决方案，但没有一个奏效，请帮助我解决问题。我的截止日期很紧迫，过去几天我一直在努力解决它，但我无法解决。

我试过的Tomcat版本：8.5、9.0.34、9.0.44

非常感谢任何帮助，请帮助我解决它。我正在使用 jdk 1.8.0_221 仅供参考，我的 tomcat 主目录中有以下 jar：el-api.jar、jasper.jar、jasper-el.jar、jsp-api.jar、jaspic-api.jar、servlet-api.jar。
