[英]Maven JavaFX Project Unable to Find FXML FIle Using GetResource?
[英]Unable to find fxml file in Javafx
我目前正在嘗試在網上關注Javafx教程,但遇到了一些問題。 我有一個3種不同包裝的項目。 第一個是:ch.makery.address,它包含主要內容;第二個是:ch.makery.model,目前為空。第三個是:ch.makery.view,它包含2個不同的fxml文件,分別對應於兩種不同的布局。 這是主要代碼:
`package ch.makery.address;
import java.io.IOException;
import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Scene;
import javafx.scene.layout.AnchorPane;
import javafx.scene.layout.BorderPane;
import javafx.stage.Stage;
public class MainApp extends Application {
private Stage primaryStage;
private BorderPane rootLayout;
@Override
public void start(Stage primaryStage) {
this.primaryStage = primaryStage;
this.primaryStage.setTitle("AddressApp");
initRootLayout();
showPersonOverview();
}
/**
* Initializes the root layout.
*/
public void initRootLayout() {
try {
// Load root layout from fxml file.
FXMLLoader loader = new FXMLLoader();
loader.setLocation(MainApp.class.getResource("view/RootLayout.fxml"));
rootLayout = (BorderPane) loader.load();
// Show the scene containing the root layout.
Scene scene = new Scene(rootLayout);
primaryStage.setScene(scene);
primaryStage.show();
} catch (IOException e) {
e.printStackTrace();
}
}
/**
* Shows the person overview inside the root layout.
*/
public void showPersonOverview() {
try {
// Load person overview.
FXMLLoader loader = new FXMLLoader();
loader.setLocation(MainApp.class.getResource("view/PersonOverview.fxml"));
AnchorPane personOverview = (AnchorPane) loader.load();
// Set person overview into the center of root layout.
rootLayout.setCenter(personOverview);
} catch (IOException e) {
e.printStackTrace();
}
}
/**
* Returns the main stage.
* @return
*/
public Stage getPrimaryStage() {
return primaryStage;
}
public static void main(String[] args) {
launch(args);
}}`
這是它返回的錯誤:

據我了解,查找fxml文件時似乎存在問題。 但是我不明白為什么。 如果有人可以幫助我,那將是完美的謝謝
(很抱歉,如果我的英語有誤,那不是我的母語)
如果您的Main
位於ch.makery.address
而您的fxml位於ch.makery.view
那么這是錯誤的:
view/RootLayout.fxml
當它嘗試從ch.makery.address.view
加載文件時。
嘗試
../view/RootLayout.fxml
代替。 (與PersonOverview
相同)
該教程中的fxml文件路徑錯誤是同樣的問題。 使用../
向上移動一個目錄應該可以修復fxml文件的路徑。
