要实现word、ppt、excel、pdf等文档在web应用端预览功能，目前一般做法为：

  在页面的显示效果：

主要用的工具：

  Openoffice4（windows、linux）；SWFTools（windows、linux）；Flexpaper插件（flexpaper_flash.js）；

首先在电脑端安装好openoffice与swftools软件，记住他们的安装位置（以windows下使用为例），安装位置路径最好不能有空格，最新版的openoffice对于各类office文档支持都较好。Java端使用openoffice需要几个jar包，可以通过maven下载或者直接把jar包引入项目：

jodconverter-core-3.0-alfresco-patched-20141024.jar（此jar包maven下载不了）

其他maven依赖：

<dependency><groupId>org.openoffice</groupId><artifactId>ridl</artifactId><version>4.1.2</version></dependency><dependency><groupId>org.openoffice</groupId><artifactId>unoil</artifactId><version>4.1.2</version></dependency><dependency><groupId>org.openoffice</groupId><artifactId>jurt</artifactId><version>4.1.2</version></dependency>
<dependency><groupId>org.openoffice</groupId><artifactId>juh</artifactId><version>4.1.2</version>
</dependency>

Java测试类：

}

Jsp页面使用flexpaper_flash.js，主要的包结构，symantec.swf和test.swf为生成的swf测试文件，其他为flexpaper需要的文件。

启动tomcat可以查看此jsp得到预览效果。
