Override error message in spring validator

Question

Say I make rest service with Spring.

Say I need custom validator wich is applied to whole type/class i.e. @Target({ElementType.TYPE}). Validator has pretty clumsy logic which cannot be reduced to subvalidators or field-validators.

So sometimes it is rather difficult to understand what exactly is wrong and I need to add different error messages.

I can't get how to do that. Is it possible?

For example like:

public class ReportConstraintValidator implements ConstraintValidator<ValidReport, Report> {

    @Autowired
    DesignRepository designRepository;

    @Override
    public void initialize(ValidReport constraintAnnotation) {
    }

    @Override
    public boolean isValid(Report report, ConstraintValidatorContext context) {
        ...
        // here goes "foo error message"
        return false;
        ...
        // here goes "bar error message"
        return false;
    }
}

Solved as M.Denium proposed

public class ReportConstraintValidator implements ConstraintValidator<ValidReport, Report> {

@Autowired
DesignRepository designRepository;

@Override
public void initialize(ValidReport constraintAnnotation) {
}

@Override
public boolean isValid(Report report, ConstraintValidatorContext context) {
    ...
    context.buildConstraintViolationWithTemplate("foo error message").addConstraintViolation();
    return false;
    ...
    context.buildConstraintViolationWithTemplate("foo error message").addConstraintViolation();
    return false;
}
}
