2. Use HTML to export a simple PDF file

 

@RequestMapping ("/pdfload") public void Pdfload (@RequestParam ("Pdfhtmldata") String Pdfhtmldata, @RequestParam (" FileName ") string filename, @RequestParam (" Borswerinfo ") string borswerinfo, HttpServletRequest request, HttpServletResponse response) {Log.info ("Pdfhtmldata:" +pdfhtmldata+ "; FileName:" +filename+ "; Borswerinfo:" +    Borswerinfo);    InputStream In=null;    OutputStream Out=null;    try {String Temppdffile=fileuploadrestcontroller.class.getresource ("/"). GetPath ();    Temppdffile=temppdffile+ "/public/upload/" +system.currenttimemillis () + ". pdf";        File Dest=new file (temppdffile);        Detects if there is a directory if (!dest.getparentfile (). exists ()) {Dest.getparentfile (). Mkdirs ();      } fileoutputstream tempout=new FileOutputStream (temppdffile);//Build an HTML page (foreground control delivery via JS)//Build a document based on HTML page Documentbuilder builder = documentbuilderfactory.newinstance (). Newdocumentbuilder ();D ocument doc = builder.parse (new Bytearrayinputstream (Pdfhtmldata.getbytes ("UTF-8"));//RootAccording to document to fill Itextrendereritextrenderer itextrenderer=new itextrenderer (); Itextrenderer.setdocument (doc, null); I Textfontresolver fontresolver = Itextrenderer.getfontresolver (); String Pdffontpath=fileuploadrestcontroller.class.getresource ("/plugins/pdf-font/simsun.ttf"). GetPath ();// Request.getsession (). Getservletcontext (). Getrealpath ("Upload/pdf/font"); Fontresolver.addfont (PdfFontPath, basefont.identity_h,basefont.not_embedded); Itextrenderer.layout ();// Use Itextrenderer to generate PDF files itextrenderer.createpdf (tempout); Tempout.flush (); Tempout.close ();//File download files DownloadFile =  New File (Temppdffile); FileName jsonobject borswerinfoobj=jsonobject.parseobject (borswerinfo), if (null!=borswerinfoobj&& "ie". equals (Borswerinfoobj.get ("browser"))) {Filename=java.net.urlencoder.encode (FileName, "UTF-8"); Filename=filename.replace ("+", "%20");// The file name with a space under IE will be converted to a plus sign Response.setheader ("CharSet", "Charset=utf-8");} else {filename=new String (filename.getbytes (), Charset.forname ("iso8859-1")), Response.setheader ("CharseT "," charset=iso8859-1 ");}  Output Settings Response.setheader ("Content-type", "Application/octet-stream");  Response.setcontenttype ("Application/octet-stream");          Response.setheader ("Content-disposition", "attachment;filename=" +filename);          Response.setcontentlengthlong (Downloadfile.length ());        In=new FileInputStream (DownloadFile);        Out=response.getoutputstream ();          Ioutils.copy (in,out);  Response.flushbuffer (); }catch (Exception e) {e.printstacktrace ();}            Finally {ioutils.closequietly (in);        ioutils.closequietly (out); }    }

  

3, the Pdfhtmldata parameter is

Export PDF file $ (' body '). Delegate (". Pdfload", "click", Function () {webindex.queryparam.limit=10000; Logger.info (Webindex.queryparam); $.ajax ({type: ' post ', url:webiface.rooturl+ '/filemanager/list/', DataType: ' JSON ') , Data:WebIndex.queryParam}). Done (function (data) {logger.info (data), if (data.code==1) {var ifile=$ (' body '). Find (' #    Load-pdf ');    var filename= "File Upload and download list. pdf";    Construct PDF to print HTML data var pdfhtmldata= ';    pdfhtmldata+= '
