java ftp上传方法

提供一个思路，大家可以参考着修改自己的方法！

/** * 上传文件到FTP * * @param file * file文件，struts2从页面得到的File类型 * * @param filePath * 要保存在FTP上的路径（文件夹） * @param fileName * * * @return 文件是否上传成功 * * @throws Exception */

public static boolean upload(File file, String filePath, String fileName) {

TelnetOutputStream to = null;

FileInputStream fi = null;

filePath = FILE_SEPARATOR （定义的路径获取）+ filePath;

try { if (file != null) {

connectFTP(); // ftpClient.setAsciiType();

if (!isDirExist(filePath.replace("\\", "/"))) {

createDir(filePath.replace("\\", "/"));

ftpClient.changeDirectory("/" + filePath.replace("\\", "/"));

}

fi = new FileInputStream(file);

to = (TelnetOutputStream) ftpClient.putFileStream(fileName, true);

byte[] bytes = new

byte[1024];

int i = fi.read(bytes);

while (i != -1) {

to.write(bytes);

i = fi.read(bytes); } }

return true;

} catch (FileNotFoundException e1) { e1.printStackTrace(); return false;

} catch (IOException e2) { e2.printStackTrace(); return false;

} catch (Exception e) { e.printStackTrace(); return false;

} finally {

if (fi != null) {

try { fi.close();

} catch (IOException e) {

e.printStackTrace();

}

}

if (to != null) {

try { to.flush();

to.close();

} catch (IOException e) { e.printStackTrace(); }

}

closeFTP();

}

}

/** * 链接FTP * * @throws FtpProtocolException */

public static void connectFTP() throws

FtpProtocolException {

try

{

ftpClient = FtpClient.create();

ftpClient.connect(new InetSocketAddress(url, port));

ftpClient.login(user, password.toCharArray());

ftpClient.setBinaryType();

} catch

(IOException e) {

e.printStackTrace();

}

}
