Antonio Goncalves updated FORGE-1617:
-------------------------------------
Description:
Some constraints need to have fields (attributes). For example, the {{URL}} constraint needs three fields : a protocol, a host, and a port :
{code}
constraint-add-field --named protocol --type String --targetConstraint URL
constraint-add-field --named host --type String --targetConstraint URL
constraint-add-field --named port --type String --targetConstraint URL
{code}
This will add the three attributes to the existing constraint {{URL}} :
{code}
@Documented
@Constraint(validatedBy = URLValidator.class)
@Target( { METHOD, FIELD, ANNOTATION_TYPE, CONSTRUCTOR, PARAMETER })
@Retention(RUNTIME)
@ReportAsSingleViolation
public @interface URL {
String message() default "{org.mycompany.myproject.constraints.URL.message}";
Class<?>[] groups() default { };
Class<? extends Payload>[] payload() default { };
String protocol() default "";
String host() default "";
int port() default -1;
@Target( { METHOD, FIELD, ANNOTATION_TYPE, CONSTRUCTOR, PARAMETER })
@Retention(RUNTIME)
@Documented
public @interface List {
URL[] value();
}
}
{code}
But it will also add the three attributes to the implementation : attributes and {{initialize}} method :
{code}
public class URLValidator implements ConstraintValidator<URL, String> {
private String protocol;
private String host;
private int port;
@Override
public void initialize(URL url) {
this.protocol = url.protocol();
this.host = url.host();
this.port = url.port();
}
@Override
public boolean isValid(String value, ConstraintValidatorContext context) {
return false;
}
}
{code}
