我需要从以下代码中获取 json 对象
JsonObject request = HttpRequestProcessor.getJsonFromRequest(request().body());
ActorRef actorRef = ActorHandler.getActorReferenceOfParameterisedActor(AControllerTasksExecutor.class,
new AControllersTaskContext(FactoryType.USER_COMMAND_FACTORY, ObjectType.PURCHASE_SHARES));
CompletionStage<JsonObject> promise = PromiseHandler.getPromise(actorRef, request, 7000);
JsonObject response = null;
Result result = null;
try {
response = promise.get(70000);
log.debug(">> response object >> {}", response);
result = PlayResultHandler.getResult(response.get("status").getAsInt(), JsonHandler.parseJsonIntoString(response));
} catch (Exception e) {
}
public class PromiseHandler {
private final static Logger log = LoggerFactory.getLogger(PromiseHandler.class);
public static <B> CompletionStage<B> getPromise(ActorRef actorRef, Object msg, int time) {
log.debug("Preparing promise. ActorRef: {}, Message-Object: {}, time: {}", actorRef, msg, time);
CompletionStagev<B> prom = CompletionStage.wrap(ask(actorRef, msg, time)).map(new Function<Object, B>() {
@SuppressWarnings("unchecked")
public B apply(Object response) {
log.debug("In Apply method. Returning Response. Response-object: {}",response);
return (B) response;
}
});
return prom;
}
}
public class AControllerTasksExecutor extends UntypedActor {
private final static Logger log = LoggerFactory
.getLogger(AControllerTasksExecutor.class);
AControllersTaskContext context = null;
public AControllerTasksExecutor(AControllersTaskContext context) {
this.context = context;
}
@Override
public void onReceive(Object arg0) throws Exception {
log.info("Message received. Processing on Message. ");
Object response = context.executesStrategy(arg0);
log.debug("Sending response back ");
getSender().tell(response, getSelf());
}
我怎样才能得到我正在做的json对象
response = promise.get(70000);
但它给了
cannot find symbol
[error] symbol: method get(int)
[error] location: variable promise of type java.util.concurrent.CompletionStage<com.google.gson.JsonObject>
[error] response = promise.get(70000);
我怎样才能做到这一点？
