Description:
|
{{@ScriptAssert}} should be allowed to be used as cross-parameter constraint.
Maybe we should also provide a dedicated constraint which makes the intention clearer and e.g. uses {{args}} as alias:
{code}
@ParametersAssert(script="args[0] == args[1]", lang="javascript")
public void resetPassword(String password, String repeated) { ... }
{code}
with
{code}
@Target({ METHOD, CONSTRUCTOR })
@Retention(RUNTIME)
@Constraint(validatedBy = {})
@Documented
@ScriptAssert(lang = "", script = "", alias = "args", validationAppliesTo = PARAMETERS)
public @interface ParametersAssert {
String message() default "{org.hibernate.validator.constraints.ParametersAssert.message}";
Class<?>[] groups() default {};
Class<? extends Payload>[] payload() default {};
@OverridesAttribute(constraint = ScriptAssert.class, name = "script")
String script();
@OverridesAttribute(constraint = ScriptAssert.class, name = "lang")
String lang();
}
{code}
