Java Implementation Attachment Preview (Openoffice+pdf.js) __js

Java Implementation Attachment Preview (Openoffice+pdf.js), convert Office documents through OpenOffice tools to PDF files, use Pdf.js for front-end display

Is the upgrade version of Openoffice+swftools+flexpaper, reduce the SWF file conversion, and Flexpaper can only preview 10 page content, original: http://blog.csdn.net/z69183787/article/ details/17468039

The conversion formats currently supported are as follows:

private static string[] Docfilelayouts = {". txt", ". Doc", ". docx", ". WPs", ". xls", ". xlsx", ". et", ". ppt", ". pptx", ". DPS" };//office Office software format
private static string[] Imgfilelayouts = {". jpg", ". gif", ". jpeg", ". png", ". bmp"};//picture format
private static string[] Pdffilelayouts = {". pdf"};//pdf format

The transformation format can be extended if other formats are required.

1, installation Apache_openoffice_4.1.2_win_x86_install_en-us.exe,

Download Connection: http://www.openoffice.org/download/index.html

2, add environment variables Path=d:\program Files (x86) \openoffice 4\program

3, execute Open_office_service.bat script, and see if the process Soffice run

4, Action New method

/**
 *. parsing article content to PDF
 * @param request
 * @param modelmap
 * @param baseaddition
 /
private void Initpdf (servletwebrequest request,modelmap modelmap,
              baseadditionbaseaddition) {
       Stringpath = "";
       if ("". Equals (Baseaddition.getexpandone ()) | | Baseaddition.getexpandone () ==null) {
              path= Kapath + baseaddition.getoperationid () + "/" + Baseaddition.getadditionid () + "/";
       }
       Invokes the transformation class Docconverter and passes the file that needs to be converted to the constructor method of the class
       docconverterd = new Docconverter (baseaddition);
       Call the Conver method to start the conversion, first execute doc2pdf () convert the Office file to PDF, and then execute pdf2swf () to convert the PDF to SWF;
       D.conver ();
       Call the Getpdfpath () method to print the converted PDF file path
       Stringpdfpath = Request.getrequest (). Getcontextpath () +path+d.getpdfname ();
       Put the relative path into the Sessio
       to save the Modelmap.put ("Pdfpath", Pdfpath);
}

4. Front Jsp,pdf loading display

<!--content-->
<div class= "mim_content" > <iframe width= "100%"
height= "700px" src= "<%=basepath %>js/pdf/web/viewer.html?file=${pdfpath} "></iframe>
</div>

Note: ${pdfpath},

A.pdf file path must be a project path

B. File name cannot contain Chinese s

5, switch to demo mode, because the use of IFRAME into the PDF page, Full-screen mode can not be used, specific reasons can ask Niang, here only give a full screen display ideas. Edit Viewer.js:

A. Display the full screen button

/*if (! Pdfview.supportsfullscreen) {
    document.getElementById (' Presentationmode '). Classlist.add (' hidden ');
    document.getElementById (' Secondarypresentationmode ').
      Classlist.add (' hidden ');
  } */

B. Change button click events for custom Processing

Request:function presentationmoderequest () {
  	//reference knowledgelucenedetail.jsp
	if ( Parent.document.isfullscreen==null | | !parent.document.isfullscreen) {
		parent.launchfullscreen ();
	} else{
		Parent.exitfullscreen ();
	}
    return true;
  }

C. Functions can hide unrelated div, you can display full screen, here use the Hide div

	var dochtml = document.documentelement;
	var docbody = document.body;
	var videobox = document.getElementById (' content ');
	var Mi_main_div = $ ("#mi_main_div");
	var Module_info_div = $ ("#module_info_div");
	var Module_info_2_div = $ ("#module_info_2_div");
	Enter Full-screen
	function Launchfullscreen () {
			var csstext = ' Width:100%;height:100%;overflow:hidden; ';
			Mi_main_div.hide ();
			Module_info_2_div.hide ();
			DocHtml.style.cssText = csstext;
			DocBody.style.cssText = csstext;
			Videobox.style.cssText = Csstext + '; ' + ' margin:0px;padding:0px;
			'; Module_info_div.removeclass (' Module_info ');
			Document. IsFullScreen = true;
	}
	Exits Full-screen
	function Exitfullscreen () {
			mi_main_div.show ();
			Module_info_2_div.show ();
			DocHtml.style.cssText = "";
			DocBody.style.cssText = "";
			Videobox.style.cssText = "";
			Module_info_div.addclass (' Module_info ');
			Document. IsFullScreen = false;
	}

JS, Java code, there are some garbage code, we see the volume, there is a feeling of discomfort, you can optimize their own.
