导入包Ftp包 commons-net-3.3.jar

 直接例子:

Ftp工具类         

package com.book.utils;

import java.io.IOException;
import java.io.InputStream;

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

public class ftpUtil {
//									("127.0.0.1", 21, "test", "test", "D:/ftp", "test.txt", innput)
	public static boolean uploadFile(String url,int port,String username, String password, String path, String filename, InputStream input) { 
	    boolean success = false; 
	    FTPClient ftp = new FTPClient(); 
	    try { 
	        int reply; 
	        ftp.connect(url, port);//连接FTP服务器 
	        //如果采用默认端口,可以使用ftp.connect(url)的方式直接连接FTP服务器 
	        ftp.login(username, password);//登录 
	        reply = ftp.getReplyCode(); 
	        if (!FTPReply.isPositiveCompletion(reply)) { 
	            ftp.disconnect(); 
	            return success; 
	        } 
	        ftp.changeWorkingDirectory(path); 
	        ftp.storeFile(filename, input);          
	         
	        input.close(); 
	        ftp.logout(); 
	        success = true; 
	    } catch (IOException e) { 
	        e.printStackTrace(); 
	    } finally { 
	        if (ftp.isConnected()) { 
	            try { 
	                ftp.disconnect(); 
	            } catch (IOException ioe) { 
	            } 
	        } 
	    } 
	    return success; 
	}
}

  

  页面代码:

	@RequestMapping("shangc")

	  public String UploadFile(HttpServletRequest request)throws IllegalStateException, IOException  {
