How to map timestamp column to JPA type?

Question

I\'m using Play! 1.2.4 and PostgreSQL 9.1. I created a table with a created_at column, of type: timestamp without time zone. It has a default val

Answer 1

You need to detach and fetch entity from db. Insert statement does not contain created_at field so it's not managed by JPA at the time of creation. In repository it would look like this:

@Transactional
public Log save(Log log) {
    this.em.persist(log);
    this.em.detach(log);
    return this.em.find(Log.class, log.getId());
}
