我找不到用于此问题的任何特定线程，很抱歉，如果以前曾有人问过这个问题。
我对JSP相当陌生，我在生产中看到以下异常，无法在本地复制。我检查了文件user-management-setup是否存在。
stackTrace[0]="org.apache.jasper.JasperException: An exception

引起问题的JSP代码：
<div class="help-wrap">
<div id="appHelp">
<%-- Don't XSS escape include tags. These attributes aren't rendered on the page and will break if any part of the "page" attribute has special characters --%>
<jsp:include page="/app/${app.name}/${instance.id}/setup/help/user-management-setup"/>
</div>
</div>
还验证了，当app.name和instance.id无效或文件不存在时，我收到了与{{1]不同的另一个错误（类似-未找到资源...）。 }}
