java 實(shí)現(xiàn)ftp上傳如何創(chuàng)建文件夾？
準(zhǔn)備條件：java實(shí)現(xiàn)ftp上傳用到了commons-net-3.3.jar包
首先建立ftphost連接
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;
;
System.out.println("連接到："?+?addr?+?":"?+?port);
System.out.print();
reply?=?;
if?(!FTPReply.isPositiveCompletion(reply))?{
;
System.err.println("FTP目標(biāo)服務(wù)器積極拒絕.");
System.exit(1);
return?false;
}else{
(username,?password);
;
;
;
System.out.println("已連接："?+?addr?+?":"?+?port);
return?true;
}
}?catch?(Exception?ex)?{
ex.printStackTrace();
System.out.println(ex.getMessage());
return?false;
}
}
然后再利用ftpclient的makeDirectory方法創(chuàng)建文件夾
public?void?createDir(String?dirname){
try{
;
System.out.println("在目標(biāo)服務(wù)器上成功建立了文件夾:?"?+?dirname);
}catch(Exception?ex){
System.out.println(ex.getMessage());
}
}
斷開host連接
public?void?disconnect(){
try?{
;
}?catch?(IOException?e)?{
e.printStackTrace();
}
}
最后是程序的調(diào)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();
}
}
