Large Objects may not be used in auto-commit mode
A large object can be stored in several records, that's why you have to use a transaction. All records are correct or nothing at all.

Instead of using @Transactional, all I did for this issue was to update this column in PostgreSQL DB from oid type to bytea type and added @Type for the @Lob field.
i.e.
ALTER TABLE person DROP COLUMN image;ALTER TABLE person ADD COLUMN image bytea;And changed
@Lobprivate byte[] image;To
@Lob@Type(type = "org.hibernate.type.ImageType")private byte[] image;
If you can, create a intermediate Entity between MyClass and file property for instance.Something like:
@Entity@Table(name="myobjects")public class MyClass { @OneToOne(cascade = ALL, fetch = LAZY) private File file;}@Entity@Table(name="file")public class File { @Lob byte[] file;}You can't use @Lob and fetch type Lazy. It doesnt work. You must have a a intermediate class.
