How to save a big file to and read it from database with hibernate with low-memory usage?

Question

I want to save some file content to database with hibernate, my model for hibernate is:

import javax.persistence.*;
import java.io.Serializable;
import static javax.persistence.AccessType.FIELD;

@Entity
@Access(FIELD)
@Table(name = "MYFILE")
public class MyFile implements Serializable {

    @Id
    @SequenceGenerator(name = "MYSEQ", sequenceName = "MYSEQ", allocationSize = 1)
    @GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "MYSEQ")
    @Column(name = "ID")
    private Long id;


    @Column(name = "FILE_CONTENT")
    @Lob
    private byte[] fileContent;

    // getters and setters

}

You can see the type of the fileContent field is byte[], and there is a @Lob on it.

It's working well, but the problem is if the files are huge, e.g. 10M, or 20M, it will use a lot of memory, which is an issue in production.

I wonder if there is any way to make it using low memory, say, use a stream instead of byte[]? But I'm not sure what is the correct solution.
