JAVA+FlexPaper+OpenOffice+SWFTools文档预览
http://blog.csdn.net/core_star/article/details/10148047
1、软件环境:
2、所需组件:
- openoffice:启动openoffice服务:soffice.exe -headless -nologo -norestore -accept=socket,host=localhost,port=8100;urp;StarOffice.ServiceManager
- swftools
- flexpaper : flexpaper_flash_debug.js,flexpaper_flash.js,jquery.js , FlexPaperViewer.swf
- OpenDocument文档转换器 JODConverter, 主要用它的jodconverter-2.2.2.jar包
3、程序源码:
- java转换器的程序代码:
[java] view plaincopy

- java文件上传并调用转换器对文件进行转换:
[java] view plaincopy
- String newFileName = null;
- // 得到当前时间自1970年1月1日0时0秒开始流失的毫秒数,将这个毫秒数作为上传文件的文件名
- long now = new Date().getTime();

- String path = ServletActionContext.getServletContext().getRealPath(uploadDir);
- path=path.replace( ‘\\‘, ‘/‘ );
- newFileName=now+agreement.getAgreeNum()+fileName.substring(fileName.lastIndexOf( "."));
- File dir = new File(path);
- dir.mkdirs();
- //删除旧文件
- if(!Stringer.isNullOrEmpty(agreement.getPath()))
- {
- File oldFile= new File(dir,agreement.getPath().substring(agreement.getPath().lastIndexOf("/")+1));
- if(oldFile.exists())
- {
- oldFile.delete();
- }
- }
- agreement.setPath(uploadDir+ "/"+newFileName);
- agreementDao.saveAgreement(agreement);
- BufferedOutputStream bos = null;
- BufferedInputStream bis = null;
- // 将上传的文件保存在本地目录
- File newFile = null;
- try {
- FileInputStream fis = new FileInputStream(file);
- bis = new BufferedInputStream(fis);
- newFile = new File(dir, newFileName);
- FileOutputStream fos = new FileOutputStream(newFile);
- bos = new BufferedOutputStream(fos);
- byte[] buf = new byte[1024];
- int len = -1;
- while ((len = bis.read(buf)) != -1) {
- bos.write(buf, 0, len);
- }
- } catch (Exception e) {
- e.printStackTrace();
- throw new Exception();
- } finally {
- try {
- if (null != bis)
- bis.close();
- if (null != bos)
- bos.close();
- } catch (Exception e) {
- e.printStackTrace();
- throw new Exception();
- }
- }
- DocConverter d = new DocConverter(converfilename);
- d.conver();
