我不知道我做错了什么,但我不能包括JSTL.我有jstl-1.2.jar,但不幸的是我得到了例外:
org.apache.jasper.JasperException: The absolute uri: http://java.sun.com/jstl/core cannot be resolved in either web.xml or the jar files deployed with this application

在升级之后,Tomcat 8.5在启动期间抛出FileNotFoundException.
下面是其中一个例外,它引发了超过10个类似的例外.
我不知道这些罐子的用途,换句话说,我没有<dependency>在pom.xml中添加这些罐子.
