Question

每次我的程序尝试读取或写入文件时，都会收到以下消息：

[System]: LoadConfig >> Config file is missing or corrupt!
C:\Users\Cardinal System\AppData\Roaming\OrlowBase\Run.config (Access is denied)

我在互联网上看了这个，每个遇到这个问题的人都只是想读一个目录，这与写文件的方式相同。我仔细检查了所有内容，但仍然是throw exception。我尝试以管理员身份运行该程序，但是没有做任何事情：/

如果查看我的代码，您可以看到我记录了所有内容。我将提供我的日志副本。

这是我的阅读方法：

public static ArrayList<String> readConfig(){

    ArrayList<String> list = new ArrayList<String>();

    try {
        Scanner sc = new Scanner(searchForConfig(baseDir));
        //searchForConfig(baseDir) always will return a file.

        while(sc.hasNextLine()){
            list.add(sc.nextLine());
        }

        sc.close();

        return list;
    } catch (FileNotFoundException e) {
        Logger.addElement("[System]: LoadConfig >> Config file is missing or corrupt!");
        Logger.addElement(e.getMessage());
    }

    list.add("Nothing");

    return list;
}

我的写作方法如下：

public static boolean createNewFile(String Name, String Path, ArrayList<String> Content, boolean override){

    File file2 = new File(Path + dash + Name);

    if(override == false & file2.exists()){

        Name += "1";

    }else{
        if(override == true & file2.exists()){
            file2.delete();
        }
    }

    if(!(Name.indexOf(".") > 0)){
        Name += ".cardinal";
    }

    File file = new File(Path);
    if(!file.isDirectory() | !file.exists()){
        Logger.addElement("[FileWriter]: NewFile >> New file path is invalid.");
        Logger.addElement("[FileWriter]: NewFile >> Creating dirs at path.");
        file.mkdirs();
    }


    try {

        PrintWriter pw = new PrintWriter(Path + dash + Name, "UTF-8");

        for(int i = 0; i < Content.size(); i++){
            pw.println(Content.get(i));
        }
        Logger.addElement("[FileWriter]: NewFile >> Creating file " + Name + " at " + Path + dash);
        pw.close();
        return true;

    } catch (FileNotFoundException e) {
        Logger.addElement("[FileWriter]: NewFile >> FileNotFoundException.");
        Logger.addElement(e.getMessage());
        return false;
    } catch (UnsupportedEncodingException e) {
        Logger.addElement("[FileWriter]: NewFile >> UnsupportedEncodingException.");
        Logger.addElement(e.getMessage());
        return false;
    }
}

更新我将记录器更改为记录stacktraces并获得更多信息。它有点冗长，但一切都在那里：

Answer 1

检查Orlowbase文件夹上用户的权限。当我拒绝读取/写入/总控制的权限时，我得到了您显示的异常，当我允许它们时，您的程序运行正常。

Answer 2

这可能是许可问题。您正在运行该应用程序的用户是什么？除了“红衣主教系统”以外的一些用户？检查对C:\Users\Cardinal System\AppData\Roaming\OrlowBase\*
捕获FileNotFoundException时不要吞下stacktrace。它可能会引导你找到根本原因。

更新： “AppData”是用户特定的文件夹，只能由用户和管理员访问。在这里查看更多信息： Can any user access the %APPDATA% folder

读/写FileNotFoundException（访问被拒绝）
