[Java知识库]java 通过 SmbFile 类操作共享文件夹(1)

四、上传文件

/**

• 上传文件

• @param remoteUrl

• @param shareFolderPath

• @param localFilePath

• @param fileName

*/

public static void uploadFileToSharedFolder(String remoteUrl, String shareFolderPath, String localFilePath, String fileName) {

InputStream inputStream = null;

OutputStream outputStream = null;

try {

File localFile = new File(localFilePath);

inputStream = new FileInputStream(localFile);

// smb://userName:passWord@host/path/shareFolderPath/fileName

SmbFile smbFile = new SmbFile(remoteUrl + shareFolderPath + “/” + fileName);

smbFile.connect();

outputStream = new SmbFileOutputStream(smbFile);

byte[] buffer = new byte[4096];

int len = 0; // 读取长度

while ((len = inputStream.read(buffer, 0, buffer.length)) != -1) {

outputStream.write(buffer, 0, len);

}

// 刷新缓冲的输出流

outputStream.flush();

} catch (FileNotFoundException e) {

e.printStackTrace();

} catch (MalformedURLException e) {

e.printStackTrace();

} catch (IOException e) {

e.printStackTrace();

} finally {

try {

outputStream.close();

inputStream.close();

} catch (IOException e) {

e.printStackTrace();

}

}

}

五、下载文件

/**

• 下载文件到浏览器

• @param httpServletResponse

• @param remoteUrl

• @param shareFolderPath

• @param fileName

*/

public static void downloadFileToBrowser(HttpServletResponse httpServletResponse, String remoteUrl, String shareFolderPath, String fileName) {

SmbFile smbFile;

SmbFileInputStream smbFileInputStream = null;

OutputStream outputStream = null;

try {

// smb://userName:passWord@host/path/shareFolderPath/fileName

smbFile = new SmbFile(remoteUrl + shareFolderPath + “/” + fileName);

smbFileInputStream = new SmbFileInputStream(smbFile);

httpServletResponse.setHeader(“content-type”, “application/octet-stream”);

httpServletResponse.setContentType(“application/vnd.ms-excel;charset=UTF-8”);

httpServletResponse.setHeader(“Content-disposition”, “attachment; filename=” + fileName);

// 处理空格转为加号的问题

httpServletResponse.setHeader(“Content-Disposition”, “attachment; fileName=” + fileName + “;filename*=utf-8’’” + URLEncoder.encode(fileName, “UTF-8”).replaceAll("\+", “%20”));

outputStream = httpServletResponse.getOutputStream();

byte[] buff = new byte[2048];

int len;

while ((len = smbFileInputStream.read(buff)) != -1) {

outputStream.write(buff, 0, len);

}

} catch (MalformedURLException

e) {

e.printStackTrace();

} catch (SmbException e) {

e.printStackTrace();

} catch (UnknownHostException e) {

e.printStackTrace();

} catch (IOException e) {

e.printStackTrace();

}

finally {

try {

outputStream.close();

smbFileInputStream.close();

} catch (IOException e) {

e.printStackTrace();

}

}

}

/**

• 下载文件到指定文件夹

• @param remoteUrl

• @param shareFolderPath

• @param fileName

• @param localDir

*/

public static void downloadFileToFolder(String remoteUrl, String shareFolderPath, String fileName, String localDir) {

InputStream in = null;

OutputStream out = null;

try {

SmbFile remoteFile = new SmbFile(remoteUrl + shareFolderPath + File.separator + fileName);

File localFile = new File(localDir + File.separator + fileName);

in = new BufferedInputStream(new SmbFileInputStream(remoteFile));

out = new BufferedOutputStream(new FileOutputStream(localFile));

byte[] buffer = new byte[1024];

while (in.read(buffer) != -1) {

out.write(buffer);

buffer = new byte[1024];

}

} catch (Exception e) {

e.printStackTrace();

} finally {

try {

out.close();

in.close();

} catch (IOException e) {

e.printStackTrace();

}

}

}

六、删除文件

/**

• 删除文件

• @param remoteUrl

• @param shareFolderPath

• @param fileName

*/

public static void deleteFile(String remoteUrl, String shareFolderPath, String fileName) {

SmbFile SmbFile;

try {

// smb://userName:passWord@host/path/shareFolderPath/fileName
