I have the following class (from a simple Spring tutorial)
public class CarValidator implements Validator {
public boolean supports(Class aClass) {
return Car.class.equals(aClass);
}
public void validate(Object obj, Errors errors) {
Car car = (Car) obj;
ValidationUtils.rejectIfEmptyOrWhitespace(errors, "model", "field.required", "Required field");
ValidationUtils.rejectIfEmptyOrWhitespace(errors, "price", "field.required", "Required field");
if( ! errors.hasFieldErrors("price")) {
if (car.getPrice().intValue() == 0) {
errors.rejectValue("price", "not_zero", "Can't be free!");
}
}
}
}
Where the Validator class is the org.springframework.validation.Validator class from Spring 2.5.
The supports method is showing a warning (Class is a raw type. References to generic type Class should be parameterized), if I try to add parameters to this such as
public boolean supports(Class<?> aClass) ...
I get the following error:
The method supports(Class<?>) of type CarValidator has the same erasure as supports(Class) of type Validator but does not override it
There are lots of threads about this type of question, but I want to get a complete answer and actually understand it without 'hiding' the problem with a @SupressWarnings!
