JavaNIO 下载网络文件保存本地报java.nio.file.AccessDeniedException:无权限操作

JavaNIO 下载文件保存本地报java.nio.file.AccessDeniedException:无权限操作

异常代码如下：

    /**     * nio下载文件到本地并保存     * @param url     * @param filePath     * @param fileName     */    public static void downloadByNIO(String url, String filePath, String fileName) {        try (InputStream in = new URL(url).openStream()) {            Path target = Paths.get(filePath, fileName);            Files.createDirectories(target.getParent());            Files.copy(in, target, StandardCopyOption.REPLACE_EXISTING);        } catch (IOException e) {            e.printStackTrace();        }    }

异常信息如下：
java.nio.file.AccessDeniedException:文件路径

处理方法：添加文件的读写权限

    /**     * nio下载文件到本地并保存     * @param url     * @param filePath     * @param fileName     */    public static void downloadByNIO(String url, String filePath, String fileName) {        try (InputStream ins = new URL(url).openStream()) {            Path target = Paths.get(filePath, fileName);            //设置获取一律权限            Set<PosixFilePermission> permissions = PosixFilePermissions.fromString("rwxrwxrwx");            FileAttribute<Set<PosixFilePermission>> fileAttributes = PosixFilePermissions.asFileAttribute(permissions);            Files.createDirectories(target.getParent(),fileAttributes);            Files.copy(ins, target, StandardCopyOption.REPLACE_EXISTING);        } catch (IOException e) {            e.printStackTrace();        }    }
