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
