严重: Servlet.service() for servlet [dispatcherServlet] in context with path [/501] threw exception

报错内容

严重: Servlet.service() for servlet [dispatcherServlet] in context with path [/501] threw exception [Handler processing failed; nested exception is java.lang.NoClassDefFoundError: javax/servlet/jsp/jstl/core/Config] with root cause

报错解决

看见javax/servlet/jsp/jstl/core/Config的问题，解决的思路有jar版本不适配，缺少jar包，然后我对比之前的demo发现缺少了jstl依赖包，导入并添加到WEB_INF/lib下后没有问题了。
