java 通过 SmbFile 类操作共享文件夹的示例

作者:素小暖

这篇文章主要介绍了java 通过 SmbFile 类操作共享文件夹,本文通过实例代码给大家介绍的非常详细,对大家的学习或工作具有一定的参考借鉴价值,需要的朋友可以参考下

一、添加依赖

在pom.xml文件夹中添加如下的依赖就可以引用SmbFile类的jar包。

<dependency>
  <groupId>jcifs</groupId>
  <artifactId>jcifs</artifactId>
  <version>1.3.17</version>
</dependency>

二、读取文件

/**
 * 读取共享文件夹下的所有文件(文件夹)的名称
 * @param remoteUrl
 */
public static void getSharedFileList(String remoteUrl) {
 SmbFile smbFile;
 try {
  // smb://userName:passWord@host/path/
  smbFile = new SmbFile(remoteUrl);
  if (!smbFile.exists()) {
   System.out.println("no such folder");
  } else {
   SmbFile[] files = smbFile.listFiles();
   for (SmbFile f : files) {
    System.out.println(f.getName());
   }
  }
 } catch (MalformedURLException e) {
  e.printStackTrace();
 } catch (SmbException e) {
  e.printStackTrace();
 }
}

三、创建文件夹

/**
 * 创建文件夹
 * @param remoteUrl 
 * @param folderName
 * @return
 */
public static void smbMkDir(String remoteUrl, String folderName) {
 SmbFile smbFile;
 try {
  // smb://userName:passWord@host/path/folderName
  smbFile = new SmbFile(remoteUrl + folderName);
  if (!smbFile.exists()) {
   smbFile.mkdir();
  }
 } catch (MalformedURLException e) {
  e.printStackTrace();
 } catch (SmbException e) {
  e.printStackTrace();
 }
}

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
  SmbFile = new SmbFile(remoteUrl + shareFolderPath + "/" + fileName);
  if (SmbFile.exists()) {
   SmbFile.delete();
  }
 } catch (MalformedURLException e) {
  e.printStackTrace();
 } catch (SmbException e) {
 e.printStackTrace();
 }
}

删除文件夹将路径指向要删除的文件夹即可。
