public @interface Constraint
    Meta annotation to declare a constraint annotation. Every custom constraint annotation meta-annotated with this very annotation must implement the following fields:
    • String message() - the message to be used if this constraint is violated.
    • Class<?>[] groups() default {}; - the validation group. See GroupSequence. If a constraint gets applied without any specific group then Default is assumed.
    • Class<? extends Payload>[] payload() default {}; - Custom Payload for the contstraint.
