JSR303's payload attribute values are limited to class references.
The idea is to allow the specification of an additional String value for each payload declaration allowing more flexible configurations.
For example:
{code}
public @interface Payload {
Class< ? > type();
String value();
}
{code}
{code}
@interface MinLength {
Payload[] payload() default {};
// ...
}
{code}
{code}
class Account
{
@MinLength(value=4, payload = {
@Payload(type=ErrorCode.class, value="1234"),
@Payload(type=When.class, value="groovy:this.owner != null && this.foobar > 3")
})
String name;
}
{code}
