我使用IDEA Intellij。Javafx加載xml文件奇怪的錯誤
我有一個問題,我可以加載某些XML文件,但其他人不能。
例如,我可以加載gameFrame和示例fxml文件。
但沒有啓動畫面或的MainView FXML文件
MainView not being able to load
一些彈出是例外的: 的InvocationTargetException RuntimeException的:異常在應用程序啓動方法 javafx.fxml。 LoadException ClassNotFoundException:view.MainView
當我點擊問題的源頭時,它會指引我:startLayout = loader.load();行,當我在啓動方法中調用它。
重建程序並不能解決問題。 我看到一些網站提到有關資源文件沒有被提出的東西?那可能是?如果是的話,有人可以更多地瞭解它。
下面是代碼:
package sample;
import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Scene;
import javafx.scene.layout.Pane;
import javafx.stage.Stage;
import java.io.IOException;
public class Main extends Application {
private Pane startLayout, gameFrame;
private Stage primaryStage;
//
@Override
public void start(Stage primaryStage) throws Exception {
this.primaryStage = primaryStage;
this.primaryStage.setTitle("Ron");
showStartScreen();
}
//
public void showStartScreen() throws IOException {
FXMLLoader loader = new FXMLLoader();
loader.setLocation(Main.class.getResource("/view /mainView.fxml"));
startLayout = loader.load();
Scene scene = new Scene(startLayout);
primaryStage.setScene(scene);
primaryStage.show();
}
public static void main(String[] args) {
launch(args);
}
}
錯誤消息:
