IntelliJ does't have @NotBlank

Question

So im running my program and I need to setup @NotNull from import javaz.validation.constraints.NotBlank; All there is

 @NonNull
    private final String firstName;

and import org.springframework.lang.NonNull;

How do I install @NotNull or is @NonNull the same thing?
