Files.write（path.get（），line，utf8）-java.nio.file.AccessDeniedException

我正在尝试在服务器端使用以下代码向文件中写入一小行（约150个字符）：

public void printToFile(String filePath, List<String> printLine) {

    Charset utf8 = StandardCharsets.UTF_8;
    List<String> lines = Arrays.asList("1st line", "2nd line");

    try {
        Files.write(Paths.get("file5-test.txt"), lines, utf8);

    } catch (IOException e) {
        e.printStackTrace();
    }

    //Done
}

get（“file5 test.txt”）不是绝对路径。确保使用绝对路径

另外，请检查文件是否存在，如果文件存在，则应使用file.canWrite（）检查文件是否具有写入权限。

答案是，在Windows 8.1下，无法在c:\目录中创建文件。如果我将其更改为C:\Users\Glyndwr\Documents，则它可以工作。因此，我需要接受来自用户的目标文件夹（我认为这是不可能的；它必须是目标文件），并检查它是否不在c:\

问候,

是否允许您的java进程写入当前工作目录？从外观上看，您没有写入文件所在目录的权限。您好Sotirios Delimanolis和@MintyFresh，谢谢您的帮助。如何授予应用程序写入C:\的权限？另外，我如何确保应用程序对运行此应用程序的所有用户都有写入目录的权限？你好，格林。你好，斯瓦蒂，谢谢你的帮助。我将文件更改为“C:\\file5 test.txt”，新文件路径（java.nio.file.AccessDeniedException:C:\file5 test.txt）也出现了相同的错误。该文件当前不存在，我计划通过在文件名中添加时间戳来防止这种情况发生。你好，格林
