With the Oval validation framework (http://oval.sourceforge.net/) it is possible to create custom annotation based constraints (http://oval.sourceforge.net/userguide.html#d4e493).
My intention is to generate an OVal XML configuration file out of some constraint definitions, that's why I would like to do the complete OVal constraint definition with the XML configuration (http://oval.sourceforge.net/userguide.html#d4e551).
I can define all the constraints I want in the XML configuration file except for the custom constraint.
Annotation based I have the following code:
import java.lang.annotation.ElementType;
import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;
import java.lang.annotation.Target;
import net.sf.oval.exception.ConstraintsViolatedException;
@Retention(RetentionPolicy.RUNTIME)
@Target({ ElementType.FIELD, ElementType.PARAMETER, ElementType.METHOD })
@net.sf.oval.configuration.annotation.Constraint(checkWith = UpperCaseCheck.class)
public @interface UpperCase {
/**
* Message to be used for the ConstraintsViolatedException
*
* @see ConstraintsViolatedException
*/
String message() default "must be upper case";
}
import net.sf.oval.Validator;
import net.sf.oval.configuration.annotation.AbstractAnnotationCheck;
import net.sf.oval.context.OValContext;
public class UpperCaseCheck extends AbstractAnnotationCheck<UpperCase> {
private static final long serialVersionUID = 2715187850228144730L;
public boolean isSatisfied(Object validatedObject, Object valueToValidate, OValContext context, Validator validator) {
if (valueToValidate == null)
return true;
String val = valueToValidate.toString();
return val.equals(val.toUpperCase());
}
}
And the annotation check:
@NotNull
@UpperCase
private String p_name;
How do I define the custom constraint check (UpperCase) in my XML configuration?
