    • store

      <T> T store(GridFsObject<T,InputStream> upload)
      Stores the given GridFsObject, likely a GridFsUpload, into into a file with given name. If the GridFsObject.getFileId() is set, the file will be stored with that id, otherwise the server auto creates a new id.
      Type Parameters:
      T - id type of the underlying GridFSFile
      Parameters:
      upload - the GridFsObject (most likely a GridFsUpload) to be stored.
      Returns:
      the id of the stored file. Either an auto created value or GridFsObject.getFileId(), but never null.

      3.0

    • find

      com.mongodb.client.gridfs.GridFSFindIterable find(Query query)
      Returns all files matching the given query. Note, that currently Sort criterias defined at the Query will not be regarded as MongoDB does not support ordering for GridFS file access.
      Parameters:
      query - must not be null.
      Returns:
      GridFSFindIterable to obtain results from. Eg. by calling MongoIterable.into(java.util.Collection).

    • findOne

      @Nullable com.mongodb.client.gridfs.model.GridFSFile findOne(Query query)
      Returns a single GridFSFile matching the given query or null in case no file matches.
      Parameters:
      query - must not be null.
      Returns:
      can be null.

    • delete

      void delete(Query query)
      Deletes all files matching the given Query.

    • getResource

      GridFsResource getResource(String filename)
      Returns the GridFsResource with the given file name.
      Specified by:
      getResource in interface ResourceLoader
      Parameters:
      filename - must not be null.
      Returns:
      the resource. Use Resource.exists() to check if the returned GridFsResource is actually present.
