今天做到一个需求 是要用Java把文件上传到共享文件夹  下面是一个例子  以后备用

注：用到一个jar包 jcifs-1.3.14.jar

import java.io.BufferedInputStream;import java.io.File;import java.io.FileInputStream;import java.io.IOException;import java.net.MalformedURLException;import java.net.UnknownHostException;import jcifs.smb.SmbException;import jcifs.smb.SmbFile;import jcifs.smb.SmbFileOutputStream;import jcifs.util.LogStream;public class Smb {       private static LogStream log = LogStream.getInstance();  //打印日志 private String url = "";       private SmbFile smbFile = null; private SmbFileOutputStream smbOut = null; private static Smb smb = null; //共享文件协议 public static synchronized Smb getInstance(String url) {   if (smb == null)    return new Smb(url);   return smb; } /**   * @param url服务器路径   */ private Smb(String url) {   this.url = url;   this.init(); } public void init() {   try {    log.println("开始连接...url：" + this.url);    smbFile = new SmbFile(this.url);    smbFile.connect();    log.println("连接成功...url：" + this.url);   } catch (MalformedURLException e) {   e.printStackTrace();   log.print(e);   } catch (IOException e) {    e.printStackTrace();    log.print(e);   } } /**   * 上传文件到服务器   */ public int uploadFile(File file) {   int flag = -1;   BufferedInputStream bf = null;   try {    smbOut = new SmbFileOutputStream(this.url + "/" + file.getName(), false);    bf = new BufferedInputStream(new FileInputStream(file));    byte[] bt = new byte[8192];    int n = bf.read(bt);    while (n != -1) {     this.smbOut.write(bt, 0, n);     this.smbOut.flush();     n = bf.read(bt);    }    flag = 0;    log.println("文件传输结束...");   } catch (SmbException e) {    e.printStackTrace();    log.println(e);   } catch (MalformedURLException e) {    e.printStackTrace();    log.println(e);   } catch (UnknownHostException e) {    e.printStackTrace();    log.println("找不到主机...url：" + this.url);   } catch (IOException e) {    e.printStackTrace();    log.println(e);   } finally {    try {     if (null != this.smbOut)      this.smbOut.close();     if (null != bf)      bf.close();    } catch (Exception e2) {     e2.printStackTrace();    }   }   return flag; } public static void main(String[] args) {   //服務器地址 格式為 smb://电脑用户名:电脑密码@电脑IP地址/IP共享的文件夹   String remoteUrl = "smb://niu:0908@172.16.51.110/imashare/";    String localFile = "C:/Users/niu/Desktop/all/GFS_170221_093426.txt";  //本地要上传的文件   File file = new File(localFile);   Smb smb = Smb.getInstance(remoteUrl);   smb.uploadFile(file);// 上传文件 }}
