最详细的文件在线预览(openoffice+swftools+flexpaper)

1.1    本人使用的都是最新的软件包,版本见下图:

1.2    已经支持加载中文文件名

1.3    代码下载

1.概述

主要原理

1.通过第三方工具openoffice,将wordexcelppttxt等文件转换为pdf文件

2.通过swfToolspdf文件转换成swf格式的文件

3.通过FlexPaper文档组件在页面上进行展示

2.安装包下载

1.openoffice是Apache下的一个开放免费的文字处理软件

 下载版本:4.1.0

  下载地址:http://www.openoffice.org/zh-cn/download/

2.SWFTools是一组用来处理Flash的swf文件的工具包,我们使用它将pdf文件转成swf文件!

下载版本:swftools-2013-04-09-1007

  下载地址:http://www.swftools.org/download.html

 

3.FlexPaper是一个开源轻量级的在浏览器上显示各种文档的组件

  下载地址:FlexPaper官网下载

 

4.JODConverter一个Java的OpenDocument文件转换器,在此我们只用到它的jar包

   下载地址:JODCConverter下载

 

3.安装文件

1.将所下载的文件(JODConverter除外)进行安装,盘符可随自己设定!需要注意的是在openoffice安装完成后,当我们使用它时,需将它的服务打开。在次我们需要以命令的方式打开:

打开dos窗口,进入openoffice安装盘符,输入以下代码来启动服务:

soffice-headless -accept="socket,host=127.0.0.1,port=8100;urp;"-nofirststartwizard

注意最后一个命令前边的‘—’,可不要写错!服务起不来,项目可是继续不下去的哦.

官网启动服务截图如下:

本地截图:

 

3.开发过程

1.新建项目,将flexpaper文件中的js文件夹(包含了flexpaper_handlers.jsflexpaper.js, jquery.extensions.min.js, jquery.min.js, three.min.js这五个js文件主要是预览swf文件的插件)拷贝至网站根目录下的js文件夹;locale文件夹拷贝到根目录下,把css文件夹拷贝到根目录下,将FlexPaperViewer.swf拷贝至网站根目录下(该文件主要是用在网页中播放swf文件的播放器),目录结构如下图:

 

注:jar包去下载的文件的lib目录下找. DocConverter类方法 pdf2swf()pdf2swf命令的路径要根据实际值配置。

2.创建fileUpload.jsp

    //获取文件上传路径 

    String saveDirectory=application.getRealPath("/")+"upload"

    //String saveDirectory="D:\\upload"; 

    //打印上传路径信息 

   System.out.println(saveDirectory); 

    //每个文件最大50m 

    int maxPostSize = 50 * 1024 * 1024;

    DefaultFileRenamePolicy dfp = new DefaultFileRenamePolicy();

    MultipartRequest multi = new MultipartRequest(request,saveDirectory, maxPostSize,"UTF-8",dfp); 

    //MultipartRequest multi = newMultipartRequest(request, saveDirectory, maxPostSize,"UTF-8");

             String fileName =multi.getFilesystemName(name); 

             //获取上传文件的扩展名 

             StringextName=fileName.substring(fileName.lastIndexOf(".")+1); 

             //文件全路径 

             String lastFileName=saveDirectory+"\\" + fileName; 

             //获取需要转换的文件名,将路径名中的'\'替换为'/' 

             String converfilename =saveDirectory.replaceAll("\\\\", "/")+"/"+fileName; 

             System.out.println(converfilename); 

             //调用转换类DocConverter,并将需要转换的文件传递给该类的构造方法 

             DocConverter d = new DocConverter(converfilename); 

             //调用conver方法开始转换,先执行doc2pdf()office文件转换为pdf;再执行pdf2swf()pdf转换为swf; 

             d.conver(); 

             //调用getswfPath()方法,打印转换后的swf文件路径 

            System.out.println(d.getswfPath()); 

             //生成swf相对路径,以便传递给flexpaper播放器 

             String swfpath = "upload"+d.getswfPath().substring(d.getswfPath().lastIndexOf("/")); 

            System.out.println(swfpath);

6.部署发布

启动tomcat,部署当前web应用

地址栏输入http://localhost:8080/ctcesims/documentUpload.jsp如下图:

单击选择文件,选择您要上传的文档,然后单击上传,处理完成后,打印如下信息,如下图所示:

单击预览按钮,就会生成预览界面,如下图:

 

4.常见问题

若出现swf无法预览,请访问

http://www.macromedia.com/support/documentation/en/flashplayer/help/settings_manager04a.html#119065

将生成swf的文件夹设置为信任文件位置。

 

1.4    若文件目录与项目目录不在一起,可将附件目录在服务器中设置为虚拟目录

TOMCAT中建虚拟目录,要在server.xmlhost中添加context,如:

C:/Users/dimeng/fileStore是我文件的根目录 /fileStore访问文件的虚拟路径

如:通过/fileStore/10/2015/9/22/11.pdf访问C:/Users/dimeng/fileStore/10/2015/9/22/11.pdf

 

1.5    最后,若需要去除打印功能及logo,可重新编译 flexpaper flash文件,网上也有下载

FlexPaper参数
