有人知道是什么原因造成的吗？

Answer 1

我遇到了同样的问题：用<jsp-config> 括起来标签库解决了这个问题，例如：

<jsp-config>
         <taglib>
               <taglib-uri>
                     /projsp
               </taglib-uri>
               <taglib-location>
                     /WEB-INF/tags/taglib.tld
               </taglib-location>
         </taglib>
</jsp-config>

Answer 2

您的 web.xml 指定了规范版本：

<web-app 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_2_5.xsd"   <-- HERE
     version="2.5"

但一个（或多个）标签库与此规范版本不兼容。查看您正在使用的 web.xml，可能会回滚到较早的规范版本 - 或升级 tablibs。
