Java implementation Online Preview Doc,txt,ppt,xls and other documents, the use of Libreoffice,openoffice,swftools,jodconverter,flexpaper

Please see the attached picture.

LibreOffice the converted code:

Public String Dodoctofdplibre () {

File Inputfile = new file ("D:/1.txt");
File Inputfile = new file ("D:/ppt.ppt");
File Inputfile = new file ("D:/pptx.pptx");
File Inputfile = new file ("D:/doc.doc");
File Inputfile = new file ("D:/docx.docx");
File Inputfile = new file ("D:/xls.xls");
File Inputfile = new file ("D:/jpg.jpg");
File Inputfile = new file ("D:/gif.gif");
System.out.println ("LibreOffice start the conversion .... ...)" ................
Long starttime = new Date (). GetTime ();
//
TXT: use LibreOffice to convert PDF, conversion successful, but Chinese have garbled!!!!!
Doc: This is a DOC document in office that can be converted successfully, and Chinese is not garbled
Docx: This is the docx document in office, it can be converted successfully, and Chinese is not garbled
PPT and pptx: conversion succeeded.
XLS: Conversion successful, no Chinese garbled
XLSX: Conversion Successful
JPG and PNG: Success
String Libreofficepath = "D:/program Files (x86)/libreoffice 4";
This class exists in version 3 of Jodconverter and does not exist in version 2.2.2
Defaultofficemanagerconfiguration configuration = Newdefaultofficemanagerconfiguration ();
installation directory for LibreOffice
Configuration.setofficehome (New File (Libreofficepath));
Port number
Configuration.setportnumber (8100);
Configuration.settaskexecutiontimeout (1000 * 5L);//
Set task execution timeout to 5 minutes
Configuration.settaskqueuetimeout (1000 * 24L);/
Set task queue timeout to 24 hours
Officemanager Officemanager = Configuration.buildofficemanager ();
Officemanager.start ();
System.out.println ("... start ...");
Officedocumentconverter converter = new Officedocumentconverter (Officemanager);
File outputfile = new file ("D:/jpglibre.pdf");
Converter.convert (Inputfile, outputfile);
Converter.convert (Inputfile, STW, outputfile, pdf);
Transition End
System.out.println ("End of conversion .....") ");
String Pdfpath = Outputfile.getpath ();
Long endtime = new Date (). GetTime ();
Long time = Endtime-starttime;
System.out.println ("LibreOffice Conversion time is:" +time);
return pdfpath;
}

OpenOffice The converted code:

Public String Dodoctofdpopen () {
File Inputfile = new file ("D://unicode.txt");
File Inputfile = new file ("D:/pptx.pptx");
File Inputfile = new file ("D:/ppt.ppt");
File Inputfile = new file ("D:/docx.docx");
File Inputfile = new file ("D:/doc.doc");
File Inputfile = new file ("D:/xlsx.xlsx");
File Inputfile = new file ("D:/jpg.jpg");
File Inputfile = new file ("D:/gif.gif");
System.out
. println ("OpenOffice start the conversion ... .... ...)................. ...
TXT: use OpenOffice to convert PDF, conversion successful, but there are garbled!!!!!
The reason is that the coding format is not uniform, if the source file is Utf-8 file, there will be no garbled
DOC,DOCX,XLS,XLSX: Conversion successful, no garbled
//!!!!! Jpg,png,gif cannot be converted
Ppt.pptx can be converted

Long starttime = new Date (). GetTime ();
Openofficeconnection connection = new socketopenofficeconnection (8100);
try {
Connection.connect ();
catch (Connectexception e) {
E.printstacktrace ();
}
Documentconverter converter = new Openofficedocumentconverter (
connection);
File outputfile = new file ("D:/gifopen.pdf");
Converter.convert (Inputfile, outputfile);
Connection.disconnect ();
String Pdfpath = Outputfile.getpath ();
Long endtime = new Date (). GetTime ();
Long time = Endtime-starttime;
System.out.println ("OpenOffice Time used for:" +time);
return pdfpath;
}

PDF format to SWF-formatted code:

public void dopdftoswf (String pdfpath) {
Runtime r = Runtime.getruntime ();
System.out.println ("Pdfpath:" +pdfpath);
String Swfpath = pdfpath.substring (0,pdfpath.lastindexof ('. '));
System.out.println ("D:/program Files (x86)/swftools/pdf2swf.exe-t" +pdfpath+ "-S Flashversion=9-o" +swfpath+ ". swf");
try {
Process p = r.exec ("D:/program Files (x86)/swftools/pdf2swf.exe-t" +pdfpath+ "-S Flashversion=9-o" +swfpath+ ". swf");

catch (IOException e) {
E.printstacktrace ();
}
}
