Hibernate Validator 4+. Get all Constraints associated with a class

Question

How can I get all constraints for a class. For instance I have

class A {
   @NotNull
   private SomeBean field;
}

When I call:

ValidatorFactory factory = Validation.buildDefaultValidatorFactory();
Validator validator = factory.getValidator(); 
Set<ConstraintDescriptor<?>> descriptor =  validator.getConstraintsForClass(formClass).getConstraintDescriptors();

The set is empty. I would assume there is already some functionality in Hibernate Validator that would give me all the information about constraints in a neat way , without me having to resort to the reflection api.

Answer 1

getConstraintsForClass() returns constraints on the class itself. To get constraints on properties, you should call getConstrainedProperties().
