we upgrading our project play framework 2.1 2.2. new results structure not working, however. have changed return type result simpleresult in 'call' function in global.java file:
public class global extends globalsettings { @override public void onstart(application app) { logger.info("global on start event called"); logger.info("admin application has started"); // schedule duration application.conf long scheduleduration = play.application().configuration().getlong("schedule-duration"); logger.debug("scheduler duration :"+ scheduleduration) ; logger.debug("calling schedule service"); cancellable response1 = scheduleservice.scheduleit(scheduleduration); // schedule duration worker task expiration scheduler application.conf long workertaskexpirationduration = play.application().configuration().getlong("worker-task-scheduler-interval"); cancellable response2 = taskexpirationscheduleservice.schedule(workertaskexpirationduration); /******************fix cea-3440*************************************/ long workeremailduration = play.application().configuration().getlong("worker-email-scheduler-interval"); cancellable response3 = workeremailscheduleservice.schedule(workeremailduration); /******************fix cea-3440*************************************/ } @override public void onstop(application app) { logger.info("global on stop event called"); logger.info("application shutdown started..stopping sync service actor."); actorref syncactor = akka.system().actorfor("/user/syncserviceactor"); akka.system().stop(syncactor); logger.info("application shutdown started..stopping worker task expiration actor."); actorref taskexpirationactor = akka.system().actorfor("/user/workertaskexpireactor"); akka.system().stop(taskexpirationactor); /******************fix cea-3440*************************************/ logger.info("application shutdown started..stopping worker email actor."); actorref workertaskexpirationduration = akka.system().actorfor("/user/workertaskexpirationduration"); akka.system().stop(workertaskexpirationduration); /******************fix cea-3440*************************************/ // shut down system akka.system().shutdown(); logger.info("actor stopped , akka system shutdown successfully.."); } // cors private class actionwrapper extends action.simple { public actionwrapper(action<?> action) { this.delegate = action; } @override public promise<simpleresult> call(http.context ctx) throws java.lang.throwable { http.response response = ctx.response(); response.setheader("access-control-allow-origin", "*"); response.setheader("access-control-allow-methods", "post, get, options, put, delete"); response.setheader("allow", "*"); response.setheader("access-control-max-age", "3600"); response.setheader("access-control-allow-headers", "origin, x-requested-with, content-type, accept, referer, user-agent"); response.setheader("access-control-allow-credentials", "true"); promise<simpleresult> result = (promise<simpleresult>) this.delegate.call(ctx); return result; } } @override public action<?> onrequest(http.request request, java.lang.reflect.method actionmethod) { return new actionwrapper(super.onrequest(request, actionmethod)); } } this gives following error when compiled on browser:
i have tried resolve looking @ similar stackoverflow questions not resolve issue. relatively new play please elaborate in solution.
also, using eclipse ide following error:
the return type incompatible action.call(http.context)
thanks.
just replace simpleresult result ?
here example of action
public f.promise<result> call( http.context context ) throws throwable { if ( !authorized ) { return f.promise.promise(() -> unauthorized()); } // execute action return delegate.call( context ); } here global.java
@override public f.promise<result> onerror(http.requestheader requestheader, throwable throwable) { if(play.isdev()){ return super.onerror(requestheader, throwable); } logger.error("error : ", throwable); return f.promise.pure(controller.ok(views.html.error.render(requestheader.uri()))); } you should read https://www.playframework.com/documentation/2.2.0/migration22#new-results-structure-in-java
