[英]How to copy file from local to share with JCifs?
I can copy file from share to local. 我可以将文件从共享复制到本地。 But I want to switch, and copy a file from local to share.
但是我想切换,并从本地复制文件以共享。
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 copyTo
method: 但是我在
copyTo
方法上遇到异常:
Invalid operation for workgroups or servers
How should I copy file from local to share? 我应该如何从本地复制文件以共享?
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之类的流通过SMB协议将文件从本地磁盘复制到共享磁盘的完整解决方案(部分写入-无法将整个文件加载到内存的大文件解决方案):
// 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();
}
It was some time ago I worked with jcifs. 不久前,我与jcifs合作。 Could you try
newFile.createNewFile();
您可以尝试
newFile.createNewFile();
and then use the copyTo
. 然后使用
copyTo
。 If that doesn't work, than try newFile.getOutputStream()
and write the data to this stream instead of using copyTo
. 如果这不起作用,则尝试使用
newFile.getOutputStream()
并将数据写入此流,而不是使用copyTo
。
I´ma bit late to the party but this could be useful for other persons coming to this question. 我来晚会有点晚,但这对其他人提出这个问题可能很有用。
I upload files from local to share using streams and it´s working without any problem. 我从本地上传文件以使用流进行共享,并且可以正常工作。 My code is:
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();
An example using Java 1.7's Files class: 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...
