，如何在Java的jsp页面中预览文档
RT
文档已上传.
上载文档的路径存储在中
项目要求是单击文档名称以在jsp页面中打开文档，类似于百度文库的预览，
当前有三种PPTWORDPDF文档格式.
查找
许使用poi进行解析
但是目前，它仅解析文本，并且在解析之后，打开它的速度非常慢jsp开发文档jsp开发文档，因此绝对无法正常工作
格式和图像形式都无法解析.
纠结
还有许多其他的柔性纸被转换为SWF文件并在预览中显示
但是我还是不明白. 某些软件不是免费或开源的，因此您不能使用商业软件.
更多纠缠
谁有一个很好的演示？
等待

------解决方案--------------------
这不是那么简单. 最好在后台批处理中将所有上传的文档批量转换为PDF或某种格式. 直接在前景预览中打开PDF.
建议在转换过程中使用工具，而不仅限于Java实现；使用POI或类似工具进行分析效率太低.
------解决方案--------------------
您必须使用第三方插件，否则将无法使用它. 我们公司使用excel等第三方插件在IE中显示. 估计您在搜索中没有示例，我已经搜索了全部.
我将为您提供一个excel示例，该示例只能在IE中使用，其他浏览器不支持.
重要的是这句话
