JPA equivalent to Hibernate's @NaturalId

In Hibernate I can create a unique key using @NaturalId on several properties of the entity.

Is there a JPA equivalent annotation, something that is a part of javax.persistence?

What I usually do is add a unique constraint on the columns, using @Table(uniqueConstraints = @UniqueConstraint(columnNames={column_1, ..., column_n}))

No, there is not. You will have to use composite keys, so either EmbeddedId or IdClass depending what you prefer.
