java 通过 SmbFile 类操作共享文件夹的示例
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;
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;
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;
while (in.read(buffer) != -1) {
out.write(buffer);
buffer = new byte;
}
} 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。
