java - 将 URL 设置为我的 .fxml

Question

我无法链接我的 .fxml 文件。另外，我是java新手，还没有弄清楚如何链接东西等等。当然，我尝试在谷歌上搜索答案，但没有得到太多结果。

这是我的文件

public class loadingWindowTest extends Application{

public static void main(String[] args){
    launch(args);
}

@Override
public void start(Stage loadingWindowStage) throws Exception {
    try{
       FXMLLoader loadLoadingWindow = new FXMLLoader();
       loadLoadingWindow.setLocation( getClass().getResource("de.skullbro.pong.windows.loadingWindow.loadingWindow.fxml"));  
       loadLoadingWindow.setController( "de.skullbro.pong.windows.loadingWindow.loadingWindowController");
       Parent root = loadLoadingWindow.load();

       Scene scene = new Scene(root,(getSystemInformation.screenWidth * 0.5), (getSystemInformation.screenHeight * 0.5));

       loadingWindowStage.setScene(scene);
       loadingWindowStage.show();           
    }
    catch(Exception e){
        if(debug.DebugInformation()){
            Alert alert = new Alert(AlertType.ERROR);
            alert.setTitle("Fehler");
            alert.setHeaderText("");
            alert.setContentText(e.toString());
            alert.show();               
        }
        else{
            Alert alert = new Alert(AlertType.ERROR);
            alert.setTitle("Upps...");
            alert.setHeaderText("Something went wrong.");
            alert.setContentText("Please try to restart your Game. If this doesn't fix it contact the Developers");
            alert.show();   
        }
    }

}}

我的错误是:位置未设置

我做错了什么？我不确定我的 loadingWindow.setlocation()

<小时/>

这也不起作用:

loadLoadingWindow.setLocation(getClass().getResource("de/skullbro/pong/windows/loadingWindow/loadingWindow.fxml"));

这是我的树的图像

她是我收到的错误 nullpointerException:

Answer 1

getResource() 需要一个路径，而不是包列表:

所以你可以更改为:

loadLoadingWindow.setLocation(getClass().getResource("loadingWindow.fxml"));
