这篇文章将为大家详细讲解有关java如何实现在线预览之poi实现,excel, ppt转html的方法,小编觉得挺实用的,因此分享给大家做个参考,希望大家阅读完这篇文章后可以有所收获。
java实现在线预览
——之poi实现,excel, ppt转html,具体内容如下所示:
<强> # # #简介
java实现在线预览功能是一个大家在工作中也许会遇到的需求,如果公司有钱,直接使用付费的第三方软件或者云在线预览服务就可以了,例如永中办公室,办公室网络365 (http://www.officeweb365.com/)他们都有云在线预览服务,就是要钱0.0
如果想要免费的,可以用openoffice,还需要借助其他的工具(例如swfTools, FlexPaper等)才行,可参考这篇文章http://blog.csdn.net/z69183787/article/details/17468039,写的挺细的,实现原理就是:
1。通过第三方工具openoffice,将word、excel, ppt, txt等文件转换为pdf文件;
2。通过swfTools将pdf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。
当然如果装了Adobe Reader XI,那把pdf直接拖到浏览器页面就可以直接打开预览,这样就不需要步骤2、3了,前提就是客户装了Adobe Reader习这个pdf阅读器。
我这里介绍通过poi实现,excel, ppt转html,这样就可以放在页面上了。
