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);

The @Valid annotation applies validation rules on the provided object. The BindingResult interface contains the result of validation.
list = new ArrayList<E>(); } public ValidList(List<E> list) { this. list = list; } // Bean-like methods, used by javax. validation but ignored by JSON parsing public List<E> getList() { return list; } public void setList(List<E> list) { this.
Bean Validation or commonly known as JSR-380 is a Java standard that is used to perform validation in Java applications. To perform validation, data Items are applied constraints. As long as the data satisfies these constraints, it will be considered valid.
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.
