Question

我正在尝试使用loadPlayerDataFromFile方法从文件中加载带有文本的应用程序数据：

public void loadPlayerDataFromFile(File file) {
    XStream xstream = new XStream();
    xstream.alias("player", Player.class);

    try {
        String xml = FileUtil.readFile(file);

        ArrayList<Player> playerList = (ArrayList<Player>) xstream
                .fromXML(xml);

        playerData.clear();
        playerData.addAll(playerList);

        setPlayerFilePath(file);
    } catch (Exception e) { // catches ANY exception                        
         Dialogs.showErrorDialog(primaryStage,
         "Could not load data from file:\n" + file.getPath(),
         "Could not load data", "Error", e);             
    }
}
public File getPlayerFilePath() {
    Preferences prefs = Preferences.userNodeForPackage(GameApp.class);
    prefs.put( "playerPath", getClass().getResource("resources/PlayerList.xml").getFile());
    String filePath = prefs.get("playerPath", "default");
    if (filePath != null) {
        return new File(filePath);
    } else {
        return null;
    }
}

public void setPlayerFilePath(File file) {
    Preferences prefs = Preferences.userNodeForPackage(GameApp.class);
    if (file != null) {
        prefs.put("filePath", file.getPath());
        // Update the stage title
        //primaryStage.setTitle("Player - " + file.getName());
    } else {
        prefs.remove("filePath");
        // Update the stage title
        //primaryStage.setTitle("Player");
    }
}

当我尝试运行该应用程序时，它会显示以下错误消息：

java.nio.file.NoSuchFileException： C：\用户\％D0％90％D0％BB％D0％B5％D0％BA％D1％81％D0％B0％D0％BD％D0％B4％D1％80 \塔防游戏\ TDv2 \ BIN \应用\资源\ PlayerList.xml at sun.nio.fs.WindowsException.translateToIOException（Unknown Source） at sun.nio.fs.WindowsException.rethrowAsIOException（Unknown Source） at sun.nio.fs.WindowsException.rethrowAsIOException（Unknown Source）在sun.nio.fs.WindowsFileSystemProvider.newByteChannel（未知来自）java.nio.file.Files.newByteChannel（未知来源）at java.nio.file.Files.newByteChannel（未知来源）at java.nio.file.spi.FileSystemProvider.newInputStream（未知来源）在java.nio.file.Files.newInputStream（未知来源）at java.nio.file.Files.newBufferedReader（未知来源）at application.util.FileUtil.readFile（FileUtil.java:19）at application.GameApp.loadPlayerDataFromFile（GameApp.java:242）at application.GameApp.start（GameApp.java:85）at com.sun.javafx.application.LauncherImpl $ 5.run（未知来源）at com.sun.javafx.application.PlatformImpl $ 5.run（未知来源）at com.sun.javafx.application.PlatformImpl $ 4 $ 1.run（未知来源）at com.sun.javafx.application.PlatformImpl $ 4 $ 1.run（未知来源）at java.security.AccessController.doPrivileged（Native Method）at com.sun.javafx.application.PlatformImpl $ 4.run（未知来源）at com.sun.glass.ui.InvokeLaterDispatcher $ Future.run（未知来源）at com.sun.glass.ui.win.WinApplication._runLoop（Native Method）at com.sun.glass.ui.win.WinApplication.access $ 100（未知来源）at com.sun.glass.ui.win.WinApplication $ 3 $ 1.run（未知来源）at java.lang.Thread.run（未知来源）

首先检查你的文件C：\ Users \％d0％90％d0％bb％d0％b5％d0％ba％d1％81％d0％b0％d0％bd％d0％b4％d1％80 \ TowerDefense \ TDv2 \ bin \ application \ resources \ PlayerList.xml是否存在。如果存在，那么从jar中检查它的文件路径是否合适。

java.nio.file.NoSuchFileException：
