我想在Tomcat 8下使用符号链接JSP目录.
它在Tomcat 7中也可以这样工作:

    <Context allowLinking="true">

但似乎Tomcat 8放弃了这个功能,它开始使用资源

(http://tomcat.apache.org/migration-8.html#Web_application_resources).

我的示例用法:

ROOT/jsp目录 - > linksto - >/var/tmp/realplaceofjspfiles /

配置错误:

ROOT/META-INF/context.xml的:

<Context>
   <Resources allowLinking="true">
         <PreResources className="org.apache.catalina.webresources.DirResourceSet"   base="/var/tmp/realplaceofjspfiles" internalPath="jspdirectory"/>
    </Resources>
</Context>

它为我丢掉了这个例外:

我的项目包括Apache commons-* library。
Tomcat关机时引发异常，如果运行默认示例，则不引发异常。
