Specifying distinct sequence per table in Hibernate on subclasses

Question

Is there a way to specify distinct sequences for each table in Hibernate, if the ID is defined on a mapped superclass?

All entities in our application extend a super

Answer 1

I was not quite happy about the need to declare the sequence name on each class individually. I have checked the source code and came up with this solution:

import javax.persistence.Column;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import org.hibernate.annotations.GenericGenerator;
import org.hibernate.annotations.Parameter;
import org.hibernate.id.enhanced.SequenceStyleGenerator;

// ...

@Id
@GeneratedValue(generator = "sequenceIdGenerator")
@GenericGenerator(
        name = "sequenceIdGenerator", 
        strategy = "sequence",
        parameters = @Parameter(
                name = SequenceStyleGenerator.CONFIG_PREFER_SEQUENCE_PER_ENTITY,
                value = "true"))
@Column(updatable = false, nullable = false)
protected Long id;
