JavaFX不填充表中的数据列

Question

所以我想做一个简单的JavaFX程序，显示一些数据表。我有我的模型视图控制器，并从我可以告诉一切看起来很清楚。运行应用程序显示没有问题，除了没有数据显示在表中。这4个表格已初始化，我可以点击它们清楚地设置它们，只是没有数据放入它们。这是我的代码。

package releaseData; 
 

 
import java.io.IOException; 
 
import java.util.Observable; 
 

 
import releaseData.model.ReleaseData; 
 
import releaseData.view.ShowReleaseDataController; 
 
import javafx.application.Application; 
 
import javafx.collections.FXCollections; 
 
import javafx.collections.ObservableList; 
 
import javafx.fxml.FXMLLoader; 
 
import javafx.scene.Scene; 
 
import javafx.scene.layout.AnchorPane; 
 
import javafx.stage.Stage; 
 

 
public class MainApp extends Application { 
 
\t private Stage primaryStage; 
 
\t //must match the the type of pane in .fxml file 
 
\t private AnchorPane rootLayout; 
 
\t 
 
\t //set up a list 
 
\t private ObservableList<ReleaseData> releaseData = FXCollections.observableArrayList(); 
 

 
\t //Constructor 
 
\t public MainApp() 
 
\t { 
 
\t \t releaseData.add(new ReleaseData("Borderlands", "2K", "11/24/2010", "4/5")); 
 
\t \t releaseData.add(new ReleaseData("Half-Life 2", "Valve", "9/9/2002", "5/5")); 
 
\t \t releaseData.add(new ReleaseData("Far Cry 3", "Activision", "12/1/2012", "5/5")); 
 
\t \t releaseData.add(new ReleaseData("Goat Simulator", "Coffe-Stain", "8/1/2014", "3/5")); 
 
\t } 
 
\t /**

\t public ObservableList<ReleaseData> getReleaseData() 
 
\t { 
 
\t \t return releaseData; 
 
\t } 
 
\t 
 
\t @Override 
 
\t public void start(Stage primaryStage) 
 
\t { 
 
\t \t this.primaryStage = primaryStage; 
 
\t \t this.primaryStage.setTitle("Game Data"); 
 
\t \t initRootLayout(); 
 
\t } 
 
\t

\t \t \t FXMLLoader loader = new FXMLLoader(); 
 
\t \t \t loader.setLocation(MainApp.class.getResource("view/releaseDataOverview.fxml")); 
 
\t \t \t rootLayout = (AnchorPane) loader.load(); 
 
\t \t \t 
 
\t \t \t //Give the controller access 
 
\t \t \t ShowReleaseDataController controller = loader.getController(); 
 
\t \t \t controller.setMainApp(this); 
 
\t \t \t 
 
\t \t \t //Show scene containing the root layout 
 
\t \t \t Scene scene = new Scene(rootLayout); 
 
\t \t \t primaryStage.setScene(scene); 
 
\t \t \t primaryStage.show(); 
 
\t \t \t 
 
\t \t }catch (IOException e) {e.printStackTrace(); } 
 
\t } 
 
\t 
 
\t public Stage getPrimaryStage() 
 
\t { 
 
\t \t return primaryStage; 
 
\t }

package releaseData.view; 
 

 
import releaseData.MainApp; 
 
import releaseData.model.ReleaseData; 
 
import javafx.fxml.FXML; 
 
import javafx.scene.control.TableColumn; 
 
import javafx.scene.control.TableView; 
 

 
public class ShowReleaseDataController { 
 
\t 
 
\t @FXML 
 
\t private TableView<ReleaseData> releaseDataTable; 
 
\t @FXML 
 
\t private TableColumn<ReleaseData, String> nameColumn; 
 
\t @FXML 
 
\t private TableColumn<ReleaseData, String> publisherColumn; 
 
\t @FXML 
 
\t private TableColumn<ReleaseData, String> dateColumn; 
 
\t @FXML 
 
\t private TableColumn<ReleaseData, String> ratingColumn; 
 
\t 
 
\t private MainApp mainApp; 
 
\t 
 
\t public ShowReleaseDataController() {} 
 
\t 
 
\t 
 
\t @FXML 
 
\t private void initializer() 
 
\t { 
 
\t \t nameColumn.setCellValueFactory(cellData -> cellData.getValue().nameProperty()); 
 
\t \t publisherColumn.setCellValueFactory(cellData -> cellData.getValue().publisherProperty()); 
 
\t \t dateColumn.setCellValueFactory(cellData -> cellData.getValue().dateProperty()); 
 
\t \t ratingColumn.setCellValueFactory(cellData -> cellData.getValue().ratingProperty()); 
 
\t } 
 
\t 
 
\t public void setMainApp(MainApp mainApp) 
 
\t { 
 
\t \t this.mainApp=mainApp; 
 
\t \t releaseDataTable.setItems(mainApp.getReleaseData()); 
 
\t } 
 

 
}

我所做的一切我能想到的到f解决这个问题。如果有人能指引我正确的方向，我会非常感激！

初始化方法应该是

public void initialize() {...} 

不initializer()
