java如何远程访问一个共享目录

由于工作需要读取局域网中一台机器的 共享目录中的文件,需要jcifs-1.1.11.jar的支持,使用SMB协议协议,以下是实现了远程读取并复制到本地,然后删除本地文件的功能:

import java.io.BufferedInputStream;
import java.io.BufferedOutputStream;
import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;
import java.util.Date;

import jcifs.smb.SmbFile;
import jcifs.smb.SmbFileInputStream;

public class TestReadSmb {
public static void main(String[] args) ...{
String smbMachine="smb://10.108.23.200/temp/说明文件.txt";
String localPath="D:/temp";
File file=readFromSmb(smbMachine,localPath);
removeFile(file);
}

/** ***
* 从smbMachine读取文件并存储到localpath指定的路径
*
* @param smbMachine
*            共享机器的文件,如smb://xxx:xxx@10.108.23.112/myDocument/测试文本.txt,xxx:xxx是共享机器的用户名密码
* @param localpath
*            本地路径
* @return
*/
public static File readFromSmb(String smbMachine,String localpath){
File localfile=null;
InputStream bis=null;
OutputStream bos=null;
try ...{
SmbFile rmifile = new SmbFile(smbMachine);
String filename=rmifile.getName();
bis=new BufferedInputStream(new SmbFileInputStream(rmifile));
localfile=new File(localpath+File.separator+filename);
bos=new BufferedOutputStream(new FileOutputStream(localfile));
int length=rmifile.getContentLength();
byte[] buffer=new byte[length];
Date date=new Date();
bis.read(buffer);
bos.write(buffer);
Date end=new Date();
int time= (int) ((end.getTime()-date.getTime())/1000);
if(time>0)
System.out.println("用时:"+time+"秒 "+"速度:"+length/time/1024+"kb/秒");
} catch (Exception e) ...{
// TODO Auto-generated catch block
System.out.println(e.getMessage());

}finally{
try {
bos.close();
bis.close();
} catch (IOException e) {
//                // TODO Auto-generated catch block
e.printStackTrace();
}
}
return localfile;
}
public static boolean removeFile(File file) {
return file.delete();
}
}
