group. The following code shows the changes that should be added on the
Address
attribute of the
Student
class in order to take advantage of the group conversion
feature:
@Valid//To propagate the validation of a
student object
@ConvertGroup(from=Default.class,
to=AddressCheck.class)
private Address address;
The following code shows the joint validation attributes of the
Student
object and
attributesofthe
Address
objectafterusingthe
@ConvertGroup
annotation.Asyou
can see in the following code, we did not have to list all the groups of constraints.
Student student = new Student();
student.setId("ST23576");
student.setFirstname("Stelba");
student.setLastname("estelle");
student.setAddress(new Address());
Set<ConstraintViolation<Student>>
constraintViolations
=validator.validate(student);
assertEquals(2, constraintViolations.size());
The following code shows how to use the
@ConvertGroup.List
annotation:
//annotation
@ConvertGroup.List({
@ConvertGroup(from = Default.class, to =
Citizen.class),
@ConvertGroup(from = Salaried.class, to =
Foreign.class)
})
List<Student> studentList;
