Catching errors in Play framework. Best practice?

[Drew Hamlett]

What is the best way to catch errors in play framework. I'm just
wondering what everyone else does. Lately I've been surrounding the
entire block of each controller method with a try catch with a general
Exception and then using the error() method in the catch. Trying to
find best practice on this. Thanks.

Catching errors is only useful if you know how to handle them usually. Anything else and I would probably just return a 500 error, which i think happens already?

Play gives you a bit of magic to do this http://www.playframework.org/documentation/1.2.2/controllers#catch.  That at least gives you the opportunity to reduce duplication.

Usually, all my controller extends BaseController which is in charged of handling all the exceptions and rendering the HTTP 500 error. The MailUtils.sendErrorMail() send me an email when an exception occurs so I've not to skim trough the logs all day long.

public class BaseController extends Controller {

/**

* Catch any exception occurring into the controller

*/

@Util

@Catch(value = Exception.class)

public static void catchExceptions(Exception e) {

Logger.error(e, "BaseController catched an exception");

MailUtils.sendErrorMail(e);

error();

}

}

Hope it helps!
