我最近将我的数据和文件存储移植到了我开始真正喜欢的 Mongodb。我现在有一个看起来很奇怪的问题。
当我的应用程序尝试从 GridFS 为用户写入图像时，Tomohawk 中的文件扩展过滤器似乎正在拦截。我只希望过滤器支持我的文件上传 - 当系统将图像推送给用户时它不应该处于活动状态。关于如何阻止它拦截这些文件的任何想法都会非常有帮助。
更多细节：
我使用 Tomohawk 文件上传，并在我的 web.xml 中启用了扩展过滤器，以便使用它。我在 RichFaces MediaOutput 控件中显示图像，该控件提供了一个输出流，您可以将媒体字节流写入该输出流。当我将图像存储为文件或在 MySql 中时，一切正常。
现在我正在使用 GridFSDBFile writeTo: OutputStream 方法将我的图像写入 RichFaces MediaOutput 控件。当我尝试显示我的图像时，文件扩展过滤器似乎拦截了它，然后 Tomcat 抛出了 TokenMgrException。

这是错误：
