Java jersey validation

I'm using the validation in Java Jersey, and i'm building an application where it should be possible to save a draft of something. But before it is published, i would like it to be valid, using the annotations in the view model. When publishing, the same savemethod, for draft, is invoked. Therefor i cannot use the annotation in the method (methodName(@Valid ViewmodelName)). Can i somehow invoke a method to validate the annotations in the viewModel? Something like model->isValid(). Alternatively i could make two viewmodels; one for draft and one for published, but seems kind of double work.

Best regards

so from your comment I think what you want is to manually validate your annotated bean. This is fairly easy. What you need to do is:

  • Create a Validator implementation (my example uses hibernate validation)
  • Call validate on it and check the results

I created a small sample that illustrates that:

import java.util.Set;

import javax.validation.ConstraintViolation;
import javax.validation.Validation;
import javax.validation.Validator;
import javax.validation.constraints.NotNull;

    public class HibernaterTest {



        public static void main(String[] args) {

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

            MyModel m = new MyModel();
            m.test = null;

            Set<ConstraintViolation<MyModel>> validate = validator.validate(m);
            System.err.println(validate.size());

            m.test = "some string";

            validate = validator.validate(m);
            System.err.println(validate.size());
        }


        public static class MyModel {

            @NotNull
            String test;

        }
    }

The first validation call will print 1, while the second will print 0. This is because the model's test property originally is null.

I hope this answers your question,

Artur
