java jdk1.6环境下实现 ftp文件上传

通过JDK自带的API实现

package comcloudpowerutil;

import javaioFile;
import javaioFileInputStream;
import javaioFileOutputStream;
import javaioIOException;

import sunnetTelnetInputStream;
import sunnetTelnetOutputStream;
import sunnetftpFtpClient;

public class Ftp {

本地文件名

private String localfilename;
/
远程文件名

FTP客户端

服务器连接
@param ip 服务器IP
@param port 服务器端口
@param user 用户名
@param password 密码
@param path 服务器路径

/ 连接服务器的两种方法/
//第一种方法
// ftpClient = new FtpClient();

//第二种方法

ftpClientlogin(user, password);
// 设置成2进制传输
ftpClientbinary();

//把远程系统上的目录切换到参数path所指定的目录
ftpClientcd(path);
}
ftpClientbinary();
} catch (IOException ex) {

throw new RuntimeException(ex);
}

关闭连接

上传文件

下载文件
@param remoteFile 远程文件路径(服务器端)
@param localFile 本地文件路径(客户端)
@author 周玲斌

/
public void download(String remoteFile, String localFile) {
TelnetInputStream is = null;
FileOutputStream os = null;
try {
//获取远程机器上的文件filename，借助TelnetInputStream把该文件传送到本地。
is = ftpClientget(remoteFile);
File file_in = new File(localFile);
os = new FileOutputStream(file_in);
byte[] bytes = new byte[1024];
int c;
while ((c = isread(bytes)) != -1) {
oswrite(bytes, 0, c);

Systemoutprintln("download success");

eprintStackTrace();
} finally {
try {
if(os != null){
osclose();
}
} catch (IOException e) {
eprintStackTrace();
}
}
}
}

public static void main(String agrs[]) {

String filepath[] = { "/temp/aatxt", "/temp/registlog"};
String localfilepath[] = { "C:\\tmp\\1txt","C:\\tmp\\2log"};

Ftp fu = new Ftp();
/
使用默认的端口号、用户名、密码以及根目录连接FTP服务器
/
fuconnectServer("127001", 22, "anonymous", "IEUser@", "/temp");

//下载
for (int i = 0; i < filepathlength; i++) {
fudownload(filepath[i], localfilepath[i]);
}

String localfile = "E:\\号码txt";
String remotefile = "/temp/哈哈txt";
//上传
fuupload(localfile, remotefile);
fucloseConnect();
}
}

一、配置服务器环境
1、安装JDK
2、有数据库安装数据库
3、安装tomcat
4、修改目录tomcat/conf/serverxml 修改8080端口为80，配置Host标签 host配置帮你的域名绑定网站对应的目录
