java上传文件到远程服务器下的共享文件夹

[b][size=medium][size=x-large][color=black]1. 导入jcifs-1.3.14.1.jar架包,创建类Smb

2. 声明属性

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

3. 得到Smb和连接的方法

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);
}
}

4. 上传文件的方法

/**
* 上传文件到服务器
*/
public int uploadFile(File file) {
int flag = -1;
BufferedInputStream bf = null;
try {
this.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;
}

5. 在main方法里面测试

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://huangyuewang:iso@127.0.0.1/iso";
String localFile = "F:/宏茂达/资料/网友/fa8b64f05061c673730eec51.jpg"; //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
