Generated values in Hibernate

I have a column in my table that is mapped like this in the model object:

Code:

@Generated(GenerationTime.INSERT)
@Column(name = "other_id", nullable = false, unique = false, insertable = true, updatable = false)
private Long other;

While most of the times I want to use the generated value, there are times where I want to assign a value to this column manually. Is this possible? I tried to give a value to the column from the setter method, however this is being overwritten on insert.

You can do this by extending the Sequence Generator and overriding the generate column.
Let me know if you need more help on this.

public class CustomSequenceGenerator extends SequenceGenerator {

@Override
public Serializable generate(SessionImplementor session, Object obj)
throws HibernateException {

// Implmentation according to need.
}
}
