(WordExcelPDF文件转换成HTML整理

项目开发过程中，需求涉及到了各种文档转换为HTML或者网页易显示格式，现在将实现方式整理如下：?一、使用Jacob转换Word,Excel为HTML?“JACOB一个Java-COM中间件.通过这个组件你可以在Java应用程序中调用COM组件和Win32 libraries。”首先下载Jacob包，JDK1.5以上需要使用Jacob1.9版本(JDK1.6尚未测试)，与先前的Jacob1.7差别不大1、将压缩包解压后，Jacob.jar添加到Libraries中；2、将Jacob.dll放至“WINDOWS\SYSTEM32”下面。需要注意的是：?【使用IDE启动Web服务器时，系统读取不到Jacob.dll，例如用MyEclipse启动Tomcat，就需要将dll文件copy到MyEclipse安装目录的“jre\bin”下面。?一般系统没有加载到Jacob.dll文件时，报错信息为：“java.lang.UnsatisfiedLinkError: no jacob in java.library.path”】?新建类：Java代码?public?class?JacobUtil?{???public?static?final?int?WORD_HTML?=?8;????public?static?final?int?WORD_TXT?=?7;????public?static?final?int?EXCEL_HTML?=?44;????/**??*?WORD转HTML??*?@param?docfile?WORD文件全路径??*?@param?htmlfile?转换后HTML存放路径??*/??public?static?void?wordToHtml(String?docfile,?String?htmlfile)???{???ActiveXComponent?app?=?new?ActiveXComponent("Word.Application");?//?启动word??try??{???app.setProperty("Visible",?new?Variant(false));???Dispatch?docs?=?app.getProperty("Documents").toDispatch();???Dispatch?doc?=?Dispatch.invoke(???docs,???"Open",???Dispatch.Method,???new?Object[]?{?docfile,?new?Variant(false),???new?Variant(true)?},?new?int[1]).toDispatch();???Dispatch.invoke(doc,?"SaveAs",?Dispatch.Method,?new?Object[]?{???htmlfile,?new?Variant(WORD_HTML)?},?new?int[1]);???Variant?f?=?new?Variant(false);???Dispatch.call(doc,?"Close",?f);???}???catch?(Exception?e)???{???e.printStackTrace();???}???finally??{???app.invoke("Quit",?new?Variant[]?{});???}???}????/**??*?EXCEL转HTML??*?@param?xlsfile?EXCEL文件全路径??*?@param?htmlfile?转换后HTML存放路径??*/??public?static?void?excelToHtml(String?xlsfile,?String?htmlfile)???{???ActiveXComponent?app?=?new?ActiveXComponent("Excel.Application");?//?启动word??try??{???app.setProperty("Visible",?new?Variant(false));???Dispatch?excels?=?app.getProperty("Workbooks").toDispatch();???Dispatch?excel?=?Dispatch.invoke(???excels,???"Open",???Dispatch.Method,???new?Object[]?{?xlsfile,?new?Variant(false),???new?Variant(true)?},?new?int[1]).toDispatch();???Dispatch.invoke(excel,?"SaveAs",?D
