------解决方案--------------------
用 apache 的 FTPClient 试试：

import java.io.File;

import java.io.FileInputStream;

import java.io.IOException;

import java.io.InputStream;

import java.io.OutputStream;

 

import org.apache.commons.net.ftp.FTP;

import org.apache.commons.net.ftp.FTPClient;

 

/**

 * A program that demonstrates how to upload files from local computer

 * to a remote FTP server using Apache Commons Net API.
