Is it possible to validate a collection of objects in JSR 303 - Jave Bean Validation where the collection itself does not have any annotations but the elements contained within do?
For example, is it possible for this to result in a constraint violation due to a null name on the second person:
List<Person> people = new ArrayList<Person>();
people.add(new Person("dave"));
people.add(new Person(null));
Validator validator = Validation.buildDefaultValidatorFactory().getValidator();
Set<ConstraintViolation<List<Person>>> validation = validator.validate(people);
Yes, just add @Valid
to the collection.
Here is an example from the Hibernate Validator Reference.
public class Car {
@NotNull
@Valid
private List<Person> passengers = new ArrayList<Person>();
}
This is standard JSR-303 behavior. See Section 3.1.3 of the spec.
