Bean validation size of a List?

Question

How can I set a bean validation constraint that a List should at minimum contain 1 and at maximum contain 10 elements?

None of the following works:

@Min(1)
@Max(10)
@Size(min=1, max=10)
private List<String> list;

Answer 1

I created simple class:

public class Mock {

    @Size(min=1, max=3)
    private List<String> strings;

    public List<String> getStrings() {
        return strings;
    }

    public void set(List<String> strings) {
        this.strings = strings;
    }

}

And test:

Mock mock = new Mock();
mock.setStrings(Collections.emptyList());
final Set<ConstraintViolation<Mock>> violations1 = Validation.buildDefaultValidatorFactory().getValidator().validate(mock);
assertFalse(violations1.isEmpty());

mock.setStrings(Arrays.asList("A", "B", "C", "D"));
final Set<ConstraintViolation<Mock>> violations2 = Validation.buildDefaultValidatorFactory().getValidator().validate(mock);
assertFalse(violations2.isEmpty());

It seems that @Size annotation is working well. It comes from javax.validation.constraints.Size
