स्प्रिंग बूट 2.0.1 रिलीज में GridFSDBFile

GridFSFile gridFsdbFile = gridFsTemplate.findOne(new Query(Criteria.where("_id").is(id)));

GridFSDownloadStream gridFSDownloadStream = gridFSBucket.openDownloadStream(gridFsdbFile.getObjectId());
GridFsResource gridFsResource = new GridFsResource(gridFsdbFile,gridFSDownloadStream );

तब

file.setInputStream(gridFsResource.getInputStream());

आप इस तरह MongoConfiguration में gridFSBucket को परिभाषित कर सकते हैं

@Bean public GridFSBucket getGridFSBuckets() {
MongoDatabase db = mongoDbFactory().getDb();
return GridFSBuckets.create(db);
}
