【问题描述】：
我正在编写一个基于 Spring、Sitemesh、JPA 和 Shiro 的 Web 应用程序。这实际上是我第一次使用大多数这些框架，因为我已经使用 Struts/ibatis 很长时间了。
我遇到的问题很奇怪，我进行了几天的研究和反复试验，但一无所获。在资源加载中止的浏览器中，我在页面刷新时遇到间歇性问题。他们似乎有时会部分加载，而其他时候则完全丢失。
服务器设置为tomcat/apache。
我查看了服务器端，没有看到任何错误。
这是来自我的 web.xml 和我的 base-servlet.xml 的代码

作为一个例子，我在默认装饰器上拉入这样的资源。
<script src="<c:url value="/resources/js/functions.js" />" type="text/javascript"></script>
这似乎只在您刷新页面时发生，并且它决定加载或不加载的内容对于 /resources 下的任何内容都是零星的。
【问题讨论】：
-
可能与您的 shiro 过滤器有关，请仔细检查您的 url 映射和过滤器逻辑。
