I have two classes where one is nested in the other. I'd like to deserialize and validate incoming JSON against this structure of mine. I have a javax Validator obtained by 

Validator validator = Validation.buildDefaultValidatorFactory().getValidator();

And later I do:

Set<ConstraintViolation<Object>> validate = validator.validate(obj);

Where obj is my deserialized JSON. My nested classes are 

class Foo {

  @Min(5)
  Integer a;

  List<Bar> bars;

  static class Bar {
    @Min(2)
    Integer b;
  }
}

I know that, unless I specify @Valid annotation on my List<Bar> bars field, the validator is not going to make a recursive validation. However, I'd like the default behavior of the validator to be recursive.

Is there a way to do that when getting the instance of the Validator?

You can achieve this with @Valid, which allows for "validation cascading" (see this example)

class Foo {

  @Min(5)
  Integer a;

  @Valid
  List<Bar> bars;

  static class Bar {
    @Min(2)
    Integer b;
  }
}
