java - 更改文件夹中文件的文件权限

Question

我正在尝试更改文件夹以及文件夹中所有文件的文件权限。下面的代码适用于该文件夹。我可以设置任何参数来更改文件夹中文件的权限吗？

private void setPOSIXFilePermissions(String filePath) {
        Set<PosixFilePermission> perms = new HashSet<PosixFilePermission>();
        perms.add(PosixFilePermission.OWNER_READ);
        perms.add(PosixFilePermission.OWNER_WRITE);
        perms.add(PosixFilePermission.OWNER_EXECUTE);
        perms.add(PosixFilePermission.GROUP_READ);
        perms.add(PosixFilePermission.GROUP_EXECUTE);
        perms.add(PosixFilePermission.OTHERS_READ);
        perms.add(PosixFilePermission.OTHERS_EXECUTE);

        try {
            java.nio.file.Files.setPosixFilePermissions(Paths.get(filePath), perms);
        } catch (IOException e) {
            LOGGER.error("Failed to set file permission.", e);
        }
    }

尝试这个：

// Use:  - recursive = true to change permissions for all sub directories and sub files
//       - recursive = false for only one folder and its sub files.

public static boolean givePerms(File f, Set<PosixFilePermission> perms, boolean recursive)
{
    boolean success = givePerm(f, perms);
    if (f.isDirectory() && recursive)
    {
        File[] files = f.listFiles();
        for (File file : files)
        {
            if (!givePerms(file, perms, recursive)) success = false;
        }
    }
    return success;
}
