Dan Allen commented on SEAMINTL-7:
----------------------------------
Here's an example of how it might look (revised from Pete's slides)
@StatusReporter
public interface BookingStatusReporter
{
@ReportStatusMessage(level = INFO, defaultText = "You are booked to stay at
the {0} on {1,date}", during = TransactionPhase.AFTER_SUCCESS)
void bookingConfirmed(Hotel hotel, Date date);
}
@Inject @StatusReporter BookingStatusReporter status;
...
status.bookingConfirmed(booking.getHotel(), booking.getCheckinDate());
@StatusReporter specializes the functionality of @MessageBundle by stating the
intent to register a status message rather than return a string. It's like
@MessageLogger from weld extensions.
If we want to reuse the @Message annotation from JBoss Logging, then the
message method would instead be:
@Message(level = INFO, value = "You are booked to stay at the {0} on {1,date}")
@ReportStatus(during = TransactionPhase.AFTER_SUCCESS)
void bookingConfirmed(Hotel hotel, Date date);
In the second case, the @ReportStatus a) makes it a status message, b) has some
additional settings (such as when to add the message)
(btw, INFO is the default level, it's just shown for completeness)
I'd really like to see EL evaluation supported in the message string to make it
possible to reference property values. As you can see the above example assumes
that Hotel#toString() returns the name of the hotel. Instead we might do:
@Message(level = INFO, value = "You are booked to stay at the #{argv[1].name}
on {1,date}") @ReportStatus(during = TransactionPhase.AFTER_SUCCESS)
void bookingConfirmed(Hotel hotel, Date date);
I use the index of 1 for the first argument because I'm thinking argv[0] can
hold the name of the message key (i.e., method)
As an alternative, we could allow named arguments by annotating the method
parameters. @MessageParam assigns the method argument to the variable specified
in the annotation's value. Then you can reference it in the message string.
@Message(level = INFO, value = "You are booked to stay at the #{hotel.name} on
{1,date}") @ReportStatus(during = TransactionPhase.AFTER_SUCCESS)
void bookingConfirmed(@MessageParam("hotel") Hotel hotel, Date date);
The @MessageParam stuff should probably go into JBoss Logging.
