doc转swf,主流文档在线查看解决方案-相仿百度文档功能

doc转swf,主流文档在线查看解决方案--类似百度文档功能

引言：?

最近项目中对上传的文件需要在线查看功能（就是不用下载到本地，可以直接在网页里打开的查看），通过几周的研究终于搞定，在此总结下供有同样需求的同仁查询和使用。

?

原理：

通常的在线查看功能都是使用文档转换工具，把原始文档转换成swf文档，然后通过网页直接展示文档内容。

?

解决方案：

在前期技术研究的过程中，发现有三种解决方案，他们分别是：

1、使用 FlexPaper + Pdf2swf 组合。?

缺点是只能提供pdf转换成swf然后在线查看。要支持其他格式的话，需要先转成pdf，这样的话效率有点低。不过网上这种方式的资料挺多的。

相关资料：?www.cnblogs.com/luckyxiaoxuan/archive/2012/06/13/2548510.html

?

2、使用FlashPaper 把文档转成swf直接显示

这种方式的好处在于支持多种格式的文档转换，支持的文档格式包括（doc、docx、xls、xlsx、pdf、txt， ppt、pptx）， ppt、pptx的支持效果不怎么好，转换有些慢，要支持这两种方式的话，有专有的转换工具。

原来准备使用FlashPaper转换成swf文档，然后使用FlexPaper显示的，但是发现使用FlexPaper显示FlashPaper转成的swf存在问题，不能显示swf内容，而且不停的闪。后来想起浏览器可以直接支持swf显示的。使用<object><embed>标签即可。

还有一个好处就是这个工具免费。

?

缺点就是： 最后版本2.2，发布于2008年5月，此后不再支持；支持winxp， server2003等，不支持win7系统；

3、使用Print2Flash把文档转换成swf直接显示

这个东西比FlashPaper更强大，功能更全面，而且提供各种系统的支持。是一个非常不错的工具。

缺点就是：需要money，有需求的公司可以使用。

?

我的方案：

我选用的第二种方案，免费，而且对各种当前流行的文档都支持，同时服务器是window server 2003。下面说下具体的程序吧。

1、FlashPaper的安装?

可以在网上下载 FlashPaper2.2绿色版，地址：?http://download.csdn.net/detail/walkerjong/4420486

下载安装程序后，可以点击install.bat安装FlashPaper，若出现下面的错误：

flashpaper AddPrinterDriver stage 13: error 126 - 找不到指定的模块

错误原因： 安装操作系统的时候没有开启系统还原功能，FlashPaper需要使用该功能。

解决方案： 把安装文件包里的srclient.dll文件拷贝到c:/windows/system32/目录下。

当然也可以使用java程序自动安装，下面是我的工具类代码：FlashPaperUtil.java

说明： 下载下来的flashPaper安装程序解压后放置在 WebContent/bin/目录下。

程序自动的时候自动安装，若检测到没有使用系统还原功能，自动拷贝文件到系统system32目录下。

?

2、在上面贴出的代码中，使用FlashPaperUtil. fileToSwf()函数即可完成对可支持文档的转换。即转成swf文件。

?

3、显示转成成的swf文件。

displaySwf.jsp

处理请求的controller类中相关方法：

?

[java]?view plaincopy

1. /**?
2. ?????*?显示在线文档。?
3. ?????*?@return?
4. ?????*/??
5. ????@RequestMapping("show")??
6. ????public?String?show(String?swfUrl,?HttpServletRequest?request){??
7. ????????request.setAttribute("swfUrl",?swfUrl);??
8. ????????return?"common/displaySwf";??
9. ????}??

请求显示在线文档的url如下：

?

?

[html]?view plaincopy

1. http://localhost:8080/isap/fileManage/show.action?swfUrl=http://192.168.1.100/isap_doc/1341818769265.swf??

?

注： 在FlashPaper转各类文档的时候，看到他们相关程序打开了要转的文件，然后转换的。所以碰到问题的时候注意检查一下几点：

1、服务器上是否安装相关文档的打开程序，例如office 2007? --> docx；

2、检查服务器上的Print Spoller服务是否启动，虚拟打印需要用到该服务；

3、还是失败的话，用cmd运行FlashPaper安装程序下的install.bat, 查看错误原因。

?

ok，至此为止已经完成各种文档的转换和显示问题，希望能有同样需求的同仁们少走弯路。
