JpaItemWriter: no transaction is in progress

Question

I\'d like to use JpaItemWriter to batch persist entities. But when I use the following code to persist, I\'m told:

Hibernate: 
    select
        nextval (\'         


        

Answer 1

I solved it creating my own transactional JpaWriter:

@Component
public class CustomItemWriter extends JpaItemWriter {
    @Override
    @Transactional
    public void write(List items) {
        super.write(items);
    }
}
