java实现openoffice在线预览文档

1.openoffice需要导入的jar包

jodconverter-core-3.0-beta-4.jar
juh-3.2.1.jar
jurt-3.2.1.jar
ridl-3.2.1.jar
unoil-3.2.1.jar**加粗样式**

2.js

function windowopenfile(urlp,billid,name){var url=urlp+"?billid="+billid+"&storagetype="+name;window.open(url);}

3.后台代码

//在线打开预览文档@RequestMapping("/fileview")public String fileview(Model model,String filepath,String sourceid) throws Exception{ filepath="关.doc";//sourceid=new Base64Util().decodeToString(sourceid);final String path =request.getSession().getServletContext().getRealPath("/view/word") ;fileExists(path);final String pfdpath =request.getSession().getServletContext().getRealPath("/view/filetopdf/") ;fileExists(pfdpath);String filename=request.getSession().getServletContext().getRealPath("/vod/mp4");FileToPdf fileToPdf=new FileToPdf();String   wordfilename= StringUtils.substringBeforeLast(filepath, ".");//String wordfilename = filepath.substring(0, filepath.lastIndexOf("."));File  file=new File(pfdpath+"/"+wordfilename+".pdf");if(!file .exists()){fileToPdf.docToPdf(new File(filename+"/"+filepath),new File(pfdpath+"/"+wordfilename+".pdf"));}System.out.println("fileToPdfpath"+pfdpath+"/"+wordfilename+".pdf");String osName = System.getProperty("os.name");if(osName.toLowerCase().indexOf("windows")>-1){model.addAttribute("pdfname","/SCMS/view/filetopdf/"+wordfilename+".pdf");}else{model.addAttribute("pdfname","/view/filetopdf/"+wordfilename+".pdf");}return "/admin/manage/pdf/exportPdf.ftl";}/*** 判断文件是否存在* */public static void fileExists(String path){File file =new File(path);  //如果文件夹不存在则创建    if  (!file .exists()  && !file .isDirectory())      {       file .mkdir();    }}
