@Documented @Target(ANNOTATION_TYPE) @Retention(RUNTIME) 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.
