JAVA远程访问共享目录
1.2 jcifs
Jcifs pan>是一个用JAVA开发的SMB客户端库,利用jcifs可以操作windows共享文件,可以得到域用户,实现单点登录,最新版本为:1.3.12,官方网址:http://jcifs.samba.org/
2. 代码实现

import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

*/
public void smbGet(String remoteUrl,String localDir) {
InputStream in = null;
OutputStream out = null;
try {
SmbFile remoteFile = new SmbFile(remoteUrl);
if(remoteFile==null){
System.out.println("共享文件不存在");
return;
}

}
} catch (Exception e) {

} catch (IOException e) {

}
}
}

public void smbPut(String remoteUrl,String localFilePath) {
InputStream in = null;
OutputStream out = null;
try {

String fileName = localFile.getName();
SmbFile remoteFile = new SmbFile(remoteUrl+"/"+fileName);

public static void main(String[] args){
UploadDownloadUtil test = new UploadDownloadUtil() ;
// smb:域名;用户名:密码@目的IP/文件夹/文件名.xxx
//test.smbGet("smb://szpcg;jiang.t:xxx@192.168.193.13/Jake/test.txt", "c://") ;
test.smbPut("smb://szpcg;jiang.t:xxx@192.168.193.13/Jake", "c://test.txt") ;
}
}
2.3 remoteUrl说明
remoteUrl如何填写是值得注意的
如果是无需密码的共享,则类似如下格式:
smb://ip/sharefolder(例如:smb://192.168.0.77/test)
如果需要用户名、密码,则类似如下格式:
Smb://username:password@ip/sharefolder(例如:smb://chb:123456@192.168.0.1/test)
// smb:域名;用户名:密码@目的IP/文件夹/文件名.xxx
//test.smbGet("smb://szpcg;jiang.t:xxx@192.168.193.13/Jake/test.txt", "c://") ;
test.smbPut("smb://szpcg;jiang.t:xxx@192.168.193.13/Jake", "c://test.txt") ;
