I use Apache Tika bundle dependency for a Project to find out MimeTypes for
Files. due to some issues we have to find out through InputStream. it is
actually guaranteed to mark / reset given InputStream. Tika-Bundle includes
core and parser api and uses PoifscontainerDetector , ZipContainerDetector,
OggDetector, MimeTypes and Magic for detection. I have been debugging for 3
hours and all of Detectors mark and reset after detection. I did it in
following way.
TikaInputStream tis = null;
try {
TikaConfig config = new TikaConfig();
tikaDetector = config.getDetector();
tis = TikaInputStream.get(in);
MediaType mediaType = tikaDetector.detect(tis, new Metadata());
if (mediaType != null) {
String[] types = mediaType.toString().split(",");
for (int i = 0; i < types.length; i++) {
mimeTypes.add(new MimeType(types[i]));
}
}
} catch (Exception e) {
logger.error("Mime Type for given Stream could not be resolved: ",
e);
}
But Stream is consumed. Does anyone know how to find out MimeTypes without
consuming Stream?
