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
