File upload for normal Java FTP client

About FTP upload files is not difficult, but sometimes face the reality of the environment is very painful, today I will share, ordinary upload file file to ftp way, it satisfies most of the FTP, but there are special, the next blog will be mentioned.

Below I use a ftputil, to achieve various functions:

Our main functions here are:

Upload the files under the local folder to one of the FTP folders, if the upload is successful, the upload successful files to another folder, if the backup is successful, you can take the backup successful file deleted.

Directly on the code!

Here is the code for the file backup:

In two cases: the first is to back up all folders under one directory to another directory

The second is to back up a single file to another directory

First is the first case:

/* * Copy files back to the corresponding date directory, referencing the Xmlcopyfile method; */public Static Boolean CopyFile (String srcfilename, String destfilename) {Boolean flag = false; File Srcfile = new file (srcfilename);//Determine if the source file exists if (!srcfile.exists ()) {log.error ("source file:" + Srcfilename + "does not exist!) "); return flag;} else if (!srcfile.isdirectory ()) {Log.error ("copy failed, source file:" + Srcfilename + "is not a path!) "); return flag;}    file[] Bfile = Srcfile.listfiles ();    Flag = Filesutil.xmlcopyfile (destFileName, Bfile); return flag;} public static Boolean Xmlcopyfile (String destfilename, file[] Bfile) {//File Srcfile = new file (srcfilename);////Determine source file is No presence//if (!srcfile.exists ()) {//Log.error ("source file:" + Srcfilename + "does not exist!) ");//Return false;//} else if (!srcfile.isdirectory ()) {//Log.error (" Copy failed, source file: "+ Srcfilename +" is not a path!) ");//return false;//}//String month=destfilename = destfilename + filesutil.getformatdate (); Log.info (" Backup path: "+destfil ENAME);//Determine if the target file exists with the files DestFile = new file (destfilename); if (!destfile.exists ()) {try {Boolean flag = Destfile.mkDirs (); Log.info ("True or false:" + flag); catch (Exception e) {e.printstacktrace ();}} Copy file int byteread = 0; Number of bytes read InputStream in = Null;outputstream out = null;try {if (null = = Bfile | | Bfile.length < 1) {Log.error (file not found in file directory to be copied);} else {for (int i = 0; i < bfile.length; i++) {in = new fileinputs Tream (Bfile[i]); out = new FileOutputStream (destFileName + "/" + bfile[i].getname ()); byte[] buffer = new Byte[1024];while ( (Byteread = in.read (buffer))! =-1) {out.write (buffer, 0, byteread);} Out.close (); In.close ();}} Log.info ("Backup success!"); return true;} catch (FileNotFoundException e) {return false;} catch (IOException e) {return false;} finally {try {if (out! = null) out.cl OSE (); if (in! = null) In.close ();} catch (IOException e) {e.printstacktrace ();}}}

Second case:

/** The above method modification * Copy file backup to the corresponding date directory, referring to the XmlCopyFile2 method; */             Public Static BooleanCopyFile2 (File srcfile, String destfilename) {BooleanFlag =false; //determine if the source file exists                if(!srcfile.exists ()) {Log.error ("Source file:" + srcfile + "does not exist! "); returnFlag; } Flag=filesutil.xmlcopyfile2 (destFileName, srcfile); returnFlag; } Public Static BooleanXmlCopyFile2 (String destfilename, File Bfile) {destfilename= destFileName +filesutil.getformatdate (); Log.info ("Backup path:" +destfilename); //determine if the target file existsFile DestFile =NewFile (destFileName); if(!destfile.exists ()) {            Try {                BooleanFlag =Destfile.mkdirs (); Log.info ("True or false:" +flag); } Catch(Exception e) {e.printstacktrace (); }        }        //Copying Files        intByteread = 0;//number of bytes readInputStream in =NULL; OutputStream out=NULL; Try{ in=NewFileInputStream (Bfile); out=NewFileOutputStream (destFileName + "/" +bfile.getname ()); byte[] buffer =New byte[1024];  while((Byteread = in.read (buffer))! =-1) {out.write (buffer,0, Byteread);                    } out.close ();                                        In.close (); Log.info ("Backup Success!"); return true; } Catch(FileNotFoundException e) {return false; } Catch(IOException e) {return false; } finally {            Try {                if(Out! =NULL) Out.close (); if(In! =NULL) In.close (); } Catch(IOException e) {e.printstacktrace (); }        }    }

OK, the above is the normal way to upload ftp and backup files.
