Could not initialize class org.hibernate.ogm.datastore.mongodb.MongoDBDialect

Hibernate OGM
4

Hibernate OGM doesn’t have a GridFS annotation.

An example of using GridFS with OGM is the following:

import org.hibernate.ogm.datastore.mongodb.options.GridFSBucket;
import org.hibernate.ogm.datastore.mongodb.type.GridFS;

@Entity
public class Photo {

	public static final String BUCKET_NAME = "photos";

	@Id
	private String id;

	@GridFSBucket(BUCKET_NAME)
	private GridFS gridfs;

	private GridFS gridfsWithDefaultBucket;

       // ...

As long as you use the GridFS type from OGM you can store any byte[] or InputStream in it.

You can see the test on GitHub: https://github.com/hibernate/hibernate-ogm/tree/master/mongodb/src/test/java/org/hibernate/ogm/datastore/mongodb/test/gridfs
