我有一个GWT应用程序，我移植到GWT 2.4。 现在我木屐在这条线已过时的警告：
historyHandler.register(placeController, eventBus, defaultPlace);
“离型PlaceHistoryHandler方法寄存器（PlaceController，EventBus，地点）已过时”
有没有更好的办法在这里实现同样的结果，或者是安全的忽略警告？
public void onModuleLoad()
{
// Create ClientFactory using deferred binding so we can replace with
// different impls in gwt.xml
ClientFactory clientFactory = GWT.create(ClientFactory.class);
EventBus eventBus = clientFactory.getEventBus();
PlaceController placeController = clientFactory.getPlaceController();
// Start ActivityManager for the main widget with our ActivityMapper
ActivityMapper activityMapper = new AppActivityMapper(clientFactory);
ActivityManager activityManager = new ActivityManager(activityMapper, eventBus);
activityManager.setDisplay(appWidget);
// Start PlaceHistoryHandler with our PlaceHistoryMapper
AppPlaceHistoryMapper historyMapper = GWT.create(AppPlaceHistoryMapper.class);
PlaceHistoryHandler historyHandler = new PlaceHistoryHandler(historyMapper);
historyHandler.register(placeController, eventBus, defaultPlace);
RootPanel.get().add(appWidget);
// Goes to place represented on URL or default place
historyHandler.handleCurrentHistory();
}
}
