        </dependency>

2、核心代码说明

2.1、文件查询：指定目录下文件列表

 /*** 文件查询：指定Linux服务器目录下文件列表 **/
    public static List getFilesByDir(String dirName) throws Exception {
        List list = new ArrayList<>();
        File dir = new File(dirName);
        File[] files = dir.listFiles();
        for (File file : files) {
            String type = file.isDirectory() ? "文件夹" : "文件";
            String name = file.getName();
            String time = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss").format(new Date(file.lastModified()));
            long size = file.length();

            // 查询linux服务器的文件权限方法，windows会报错
            Set<PosixFilePermission> posixFilePermissions = Files.getPosixFilePermissions(Paths.get(file.getCanonicalPath()));
            List<String> permissons = posixFilePermissions.parallelStream().map(e -> e.name()).collect(Collectors.toList());
            String privilege = new StringBuffer()
                    .append(permissons.contains("OWNER_READ") ? "r" : "-")
                    .append(permissons.contains("OWNER_WRITE") ? "w" : "-")
                    .append(permissons.contains("OWNER_EXECUTE") ? "x" : "-")
                    .append(permissons.contains("GROUP_READ") ? "r" : "-")
                    .append(permissons.contains("GROUP_WRITE") ? "w" : "-")
                    .append(permissons.contains("GROUP_EXECUTE") ? "x" : "-")
                    .append(permissons.contains("OTHERS_READ") ? "r" : "-")
                    .append(permissons.contains("OTHERS_WRITE") ? "w" : "-")
                    .append(permissons.contains("OTHERS_EXECUTE") ? "x" : "-")
                    .toString();

            String result = type + ",名字为：" + name + "，时间为：" + time + "，大小为：" + size + "，权限为：" + privilege;
            System.out.println(result);
            list.add(result);
        }
        return list;
    }

2.2、文件及文件夹创建

/*** 文件创建 **/
    public static void createFile(String fileName) throws Exception {
        new File(fileName).createNewFile();
    }

    /*** 文件夹创建 **/
    public static void createDir(String dirName) throws Exception {
        new File(dirName).mkdirs();
    }

2.3、文件或文件夹重命名、删除

    /*** 文件或文件夹重命名 **/
    public static void renameFile(String oldPath, String newPath) throws Exception {
        new File(oldPath).renameTo(new File(newPath));
    }

    /*** 文件或文件夹删除 **/
    public static void deleteFile(String fileName) throws Exception {
        new File(fileName).deleteOnExit();
    }

2.4、文件内容读取

    /*** 读取文件内容 ***/
    public static String readFile(String fileName) throws Exception {
        List<String> strings = Files.readAllLines(Paths.get(new File(fileName).getCanonicalPath()));
        return String.join("\n", strings);
    }

2.5、文件上传

    /*** 文件上传 ***/
    public static void uploadFile(MultipartFile file, String serverFilePath) throws Exception {
        File dest = new File(serverFilePath);
        file.transferTo(dest);
    }

2.6、文件下载

 /*** 文件下载 ***/
    public static void downloadFile(File file, HttpServletResponse response) throws Exception {
        byte[] buffer = new byte[1024];
        BufferedInputStream bis = null;
        OutputStream os = null;
        try {
            if (file.exists()) {
                //设置响应
                response.setContentType("application/octet-stream;charset=UTF-8");
                response.setHeader("Access-Control-Expose-Headers", "Content-Disposition");
                response.setHeader("Content-Disposition", "attachment;filename=" + file.getName());
                response.setCharacterEncoding("UTF-8");
                os = response.getOutputStream();
                bis = new BufferedInputStream(new FileInputStream(file));
                while (bis.read(buffer) != -1) {
                    os.write(buffer);
                }
            }
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            try {
                if (bis != null) {
                    bis.close();
                }
                if (os != null) {
                    os.flush();
                    os.close();
                }
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    }
