问题描述

帮助！我被困了..我尝试运行我的主要javafx应用程序

Help! I'm stuck.. I try to run my main javafx app

这是我的代码;

@Override
public void start(Stage primaryStage) throws Exception {
    try {
        FXMLLoader loader = new FXMLLoader();
        loader.setLocation(getClass().getResource("/com/utmkl/fxml/SimulatorDisplay.fxml"));
        Parent content = (Parent)loader.load(); 

    primaryStage.setResizable(false);
    primaryStage.initStyle(StageStyle.UTILITY);
    primaryStage.setScene(new Scene(content));
    primaryStage.show();            
} catch(Exception e) {
    e.printStackTrace();
}

以下是我的文件夹结构：

推荐答案

我找到了答案..

资源需要与主类在同一文件夹结构中

the resource need to be in the same folder structure as main class

这是我的 Maven-JavaFX文件夹结构

VMCS
- src/main/java
     - com.utmkl
          VMCSManager.java
- src/main/resources
     - com.utmkl.fxml
          SimulatorDisplay.fxml

所以，正确的代码（成功运行）

So, the correct code (which success to run)

VMCSManager.java

VMCSManager.java

@Override
    public void start(Stage primaryStage) throws Exception {
        try {
            FXMLLoader loader = new FXMLLoader();
            loader.setLocation(getClass().getResource("fxml/SimulatorDisplay.fxml"));
            Parent content = loader.load(); 

            Scene scene = new Scene(content);

            primaryStage.setResizable(false);
            primaryStage.initStyle(StageStyle.UTILITY);

            primaryStage.setScene(scene);
            primaryStage.show();            
        } catch(Exception e) {
            e.printStackTrace();
        }
    }
