准备条件:java实现ftp上传用到了commons-net-3.3.jar包
首先建立ftphost连接
public boolean connect(String path, String addr, int port, String username, String password) {
try {
//FTPClient ftp = new FTPHTTPClient(addr, port, username, password)
ftp = new FTPClient()
int reply
ftp.connect(addr)
System.out.println("连接到:" + addr + ":" + port)
System.out.print(ftp.getReplyString())
reply = ftp.getReplyCode()
if (!FTPReply.isPositiveCompletion(reply)) {
ftp.disconnect()
System.err.println("FTP目标服务器积极拒绝.")
System.exit(1)
return false
}else{
ftp.login(username, password)
ftp.enterLocalPassiveMode()
ftp.setFileType(FTPClient.BINARY_FILE_TYPE)
ftp.changeWorkingDirectory(path)
System.out.println("已连接:" + addr + ":" + port)
return true
}
} catch (Exception ex) {
ex.printStackTrace()
System.out.println(ex.getMessage())
return false
}
}
然后再利用ftpclient的makeDirectory方法创建文件夹
public void createDir(String dirname){
try{
ftp.makeDirectory(dirname)
System.out.println("在目标服务器上成功建立了文件夹: " + dirname)
}catch(Exception ex){
System.out.println(ex.getMessage())
}
}
断开host连接
public void disconnect(){
try {
ftp.disconnect()
} catch (IOException e) {
e.printStackTrace()
}
}
最后是程序的调用方法
public static void main(String[] args) {
FtpUploadTest ftpupload = new FtpUploadTest()
if(ftpupload.connect("", "172.39.8.x", 20, "administrator", "abc@123")){
ftpupload.createDir("/UPLOAD")
ftpupload.disconnect()
}
}
File writeName = new File(你要存的地方)// 相对路径,如果没有则要建立一个新//的.txt文件
writeName.createNewFile()// 创建新文件,有同名的文件的话直接覆盖
FileWriter writer = new FileWriter(writeName)
BufferedWriter out = new BufferedWriter(writer)
out.write(你要写入的信息);
