Is there a @NotNull annotation for Ebean in Play Framework?

Question

I want Ebean in Play Framework to make some columns in my tables 'not null'. Is it possible to the @NotNull annotation? If yes, which package should I import? I tried with import com.avaje.ebean.validation.NotNull; but I got an error saying this package can't be found.

Answer 1

Note that the accepted answer is no longer correct.

com.avaje.ebean.validation.NotNull no longer exists and instead you can use javax.validation.constraints.NotNull

Secondly you do not need to specify @Column(nullable = false) if the @NotNull annotation is used. Ebean takes the existence of @NotNull as meaning that the DB column is not null and handles that appropriately.

Answer 2

It's indeed com.avaje.ebean.validation.NotNull;

check this topic for solution:

BTW:

You need to use @Column(nullable = false) annotation if you want you column to be not nullable (the restriction will be enforced by DB).

@NotNull is for validation.
