How to copy file from local to share with JCifs?
提问by victorio
I can copy file from share to local. But I want to switch, and copy a file from local to share.
我可以将文件从共享复制到本地。但是我想切换，从本地复制一个文件来共享。
I am trying this code:
SmbFile oldFile = new SmbFile("c:/tmp/test.xml");
SmbFile newFile = new SmbFile("smb://someone_pc/tmp/test.xml", new NtlmPasswordAuthentication("", username, password));
oldFile.copyTo(newFile);
But I am getting an exception on copyTomethod:
但是我在copyTo方法上遇到了异常：
Invalid operation for workgroups or servers

It was some time ago I worked with jcifs.
Could you try newFile.createNewFile();and then use the copyTo.
If that doesn't work, than try newFile.getOutputStream()and write the data to this stream instead of using copyTo.
前段时间我与 jcifs 一起工作。你可以尝试newFile.createNewFile();然后使用copyTo. 如果这不起作用，请尝试newFile.getOutputStream()将数据写入此流而不是使用copyTo.

I′m a bit late to the party but this could be useful for other persons coming to this question.
我参加聚会有点晚了，但这对其他提出这个问题的人可能有用。
I upload files from local to share using streams and it′s working without any problem. My code is:
我从本地上传文件以使用流共享，它的工作没有任何问题。我的代码是：
SmbFile remoteFile = new SmbFile(remotePath, auth);
SmbFileOutputStream out = new SmbFileOutputStream(remoteFile);
FileInputStream fis = new FileInputStream(localFile);
out.write(IOUtils.toByteArray(fis));
out.close();

Complete solution for copying file from local to shared disk over SMB protocol using streams like Javi_Swift(writing in parts - solution for large files where it's not possible to load whole file into memory):
使用Javi_Swift 等流通过 SMB 协议将文件从本地复制到共享磁盘的完整解决方案（分部分写入 - 无法将整个文件加载到内存中的大文件的解决方案）：
// local source file and target smb file
File fileSource = new File("C:/example.jpg");
SmbFile smbFileTarget = new SmbFile(smbFileContext, "example.jpg");
// input and output stream
FileInputStream fis = new FileInputStream(fileSource);
SmbFileOutputStream smbfos = new SmbFileOutputStream(smbFileTarget);
// writing data
try {
// 16 kb
final byte[] b = new byte[16*1024];
int read = 0;
while ((read=fis.read(b, 0, b.length)) > 0) {
smbfos.write(b, 0, read);
}
}
finally {
fis.close();
smbfos.close();
}

An example using Java 1.7's Filesclass:
使用 Java 1.7 的Files类的示例：
Path source = Paths.get("c:/tmp/test.xml");
SmbFile newFile = new SmbFile("smb://someone_pc/tmp/test.xml", new NtlmPasswordAuthentication("", username, password));
try (OutputStream out = newFile.getOutputStream())
{
Files.copy(source, out);
}

public void uploadToSmb(String destinationPath,File localFile){
public final static byte[] BUFFER = new byte[10 * 8024];
ByteArrayInputStream inputStream = null;
SmbFileOutputStream sfos = null;
try {
String user = username + ":" + password;
int lenghtOfFile = (int) localFile.length();
byte[] data = FileUtils.readFileToByteArray(localFile);
inputStream = new ByteArrayInputStream(data);
String path = destinationPath + localFile.getName();
NtlmPasswordAuthentication auth = new NtlmPasswordAuthentication(user);
remoteFile = new SmbFile(path, auth);
sfos = new SmbFileOutputStream(remoteFile);
long total = 0;
while ((count = inputStream.read(BUFFER)) > 0) {
total += count;
// publishing the progress....
// After this onProgressUpdate will be called
int percentage = (int) ((total / (float) lenghtOfFile) * 100);
publishProgress(percentage);
// publishProgress((int) ((total * 100) / lenghtOfFile));
// writing data to file
sfos.write(BUFFER,0,count);
}
sfos.flush();
inputStream.close();
sfos.close();
} catch (Exception e) {
e.printStackTrace();
}
}
this code is working Great...
这段代码很好用...
