一、添加依賴

在pom.xml文件夾中添加如下的依賴就可以引用SmbFile類的jar包。

1. <dependency>
2. <groupId>jcifs</groupId>
3. <artifactId>jcifs</artifactId>
4. <version>1.3.17</version>
5. </dependency>

二、讀取文件

1. /**
2. * 讀取共享文件夾下的所有文件(文件夾)的名稱
3. * @param remoteUrl
4. */
5. public static void getSharedFileList(String remoteUrl) {
6. SmbFile smbFile;
7. try {
8. // smb://userName:passWord@host/path/
9. smbFile = new SmbFile(remoteUrl);
10. if (!smbFile.exists()) {
11. System.out.println("no such folder");
12. } else {
13. SmbFile[] files = smbFile.listFiles();
14. for (SmbFile f : files) {
15. System.out.println(f.getName());
16. }
17. }
18. } catch (MalformedURLException e) {
19. e.printStackTrace();
20. } catch (SmbException e) {
21. e.printStackTrace();
22. }
23. }

三、創(chuàng)建文件夾

1. /**
2. * 創(chuàng)建文件夾
3. * @param remoteUrl
4. * @param folderName
5. * @return
6. */
7. public static void smbMkDir(String remoteUrl, String folderName) {
8. SmbFile smbFile;
9. try {
10. // smb://userName:passWord@host/path/folderName
11. smbFile = new SmbFile(remoteUrl + folderName);
12. if (!smbFile.exists()) {
13. smbFile.mkdir();
14. }
15. } catch (MalformedURLException e) {
16. e.printStackTrace();
17. } catch (SmbException e) {
18. e.printStackTrace();
19. }
20. }

四、上傳文件

1. /**
2. * 上傳文件
3. * @param remoteUrl
4. * @param shareFolderPath
5. * @param localFilePath
6. * @param fileName
7. */
8. public static void uploadFileToSharedFolder(String remoteUrl, String shareFolderPath, String localFilePath, String fileName) {
9. InputStream inputStream = null;
10. OutputStream outputStream = null;
11. try {
12. File localFile = new File(localFilePath);
13. inputStream = new FileInputStream(localFile);
14. // smb://userName:passWord@host/path/shareFolderPath/fileName
15. SmbFile smbFile = new SmbFile(remoteUrl + shareFolderPath + "/" + fileName);
16. smbFile.connect();
17. outputStream = new SmbFileOutputStream(smbFile);
18. byte[] buffer = new byte[4096];
19. int len = 0; // 讀取長(zhǎng)度
20. while ((len = inputStream.read(buffer, 0, buffer.length)) != -1) {
21. outputStream.write(buffer, 0, len);
22. }
23. // 刷新緩沖的輸出流
24. outputStream.flush();
25. } catch (FileNotFoundException e) {
26. e.printStackTrace();
27. } catch (MalformedURLException e) {
28. e.printStackTrace();
29. } catch (IOException e) {
30. e.printStackTrace();
31. } finally {
32. try {
33. outputStream.close();
34. inputStream.close();
35. } catch (IOException e) {
36. e.printStackTrace();
37. }
38. }
39. }

五、下載文件

1. /**
2. * 下載文件到瀏覽器
3. * @param httpServletResponse
4. * @param remoteUrl
5. * @param shareFolderPath
6. * @param fileName
7. */
8. public static void downloadFileToBrowser(HttpServletResponse httpServletResponse, String remoteUrl, String shareFolderPath, String fileName) {
9. SmbFile smbFile;
10. SmbFileInputStream smbFileInputStream = null;
11. OutputStream outputStream = null;
12. try {
13. // smb://userName:passWord@host/path/shareFolderPath/fileName
14. smbFile = new SmbFile(remoteUrl + shareFolderPath + "/" + fileName);
15. smbFileInputStream = new SmbFileInputStream(smbFile);
16. httpServletResponse.setHeader("content-type", "application/octet-stream");
17. httpServletResponse.setContentType("application/vnd.ms-excel;charset=UTF-8");
18. httpServletResponse.setHeader("Content-disposition", "attachment; filename=" + fileName);
19. // 處理空格轉(zhuǎn)為加號(hào)的問題
20. httpServletResponse.setHeader("Content-Disposition", "attachment; fileName=" + fileName + ";filename*=utf-8''" + URLEncoder.encode(fileName, "UTF-8").replaceAll("\\+", "%20"));
21. outputStream = httpServletResponse.getOutputStream();
22. byte[] buff = new byte[2048];
23. int len;
24. while ((len = smbFileInputStream.read(buff)) != -1) {
25. outputStream.write(buff, 0, len);
26. }
27. } catch (MalformedURLException e) {
28. e.printStackTrace();
29. } catch (SmbException e) {
30. e.printStackTrace();
31. } catch (UnknownHostException e) {
32. e.printStackTrace();
33. } catch (IOException e) {
34. e.printStackTrace();
35. }
36. finally {
37. try {
38. outputStream.close();
39. smbFileInputStream.close();
40. } catch (IOException e) {
41. e.printStackTrace();
42. }
43. }
44. }

1. /**
2. * 下載文件到指定文件夾
3. * @param remoteUrl
4. * @param shareFolderPath
5. * @param fileName
6. * @param localDir
7. */
8. public static void downloadFileToFolder(String remoteUrl, String shareFolderPath, String fileName, String localDir) {
9. InputStream in = null;
10. OutputStream out = null;
11. try {
12. SmbFile remoteFile = new SmbFile(remoteUrl + shareFolderPath + File.separator + fileName);
13. File localFile = new File(localDir + File.separator + fileName);
14. in = new BufferedInputStream(new SmbFileInputStream(remoteFile));
15. out = new BufferedOutputStream(new FileOutputStream(localFile));
16. byte[] buffer = new byte[1024];
17. while (in.read(buffer) != -1) {
18. out.write(buffer);
19. buffer = new byte[1024];
20. }
21. } catch (Exception e) {
22. e.printStackTrace();
23. } finally {
24. try {
25. out.close();
26. in.close();
27. } catch (IOException e) {
28. e.printStackTrace();
29. }
30. }
31. }

六、刪除文件

1. /**
2. * 刪除文件
3. * @param remoteUrl
4. * @param shareFolderPath
5. * @param fileName
6. */
7. public static void deleteFile(String remoteUrl, String shareFolderPath, String fileName) {
8. SmbFile SmbFile;
9. try {
10. // smb://userName:passWord@host/path/shareFolderPath/fileName
11. SmbFile = new SmbFile(remoteUrl + shareFolderPath + "/" + fileName);
12. if (SmbFile.exists()) {
13. SmbFile.delete();
14. }
15. } catch (MalformedURLException e) {
16. e.printStackTrace();
17. } catch (SmbException e) {
18. e.printStackTrace();
19. }
20. }

刪除文件夾將路徑指向要?jiǎng)h除的文件夾即可。
