Java实现在线预览–openOffice实现[通俗易懂]
大家好，又见面了，我是你们的朋友全栈君。
#Java实现在线预览–openOffice实现 之前有写了poi实现在线预览的文章，里面也说到了使用openOffice也可以做到，这里就详细介绍一下。 我的实现逻辑有两种： 一、利用jodconverter(基于OpenOffice服务)将文件( .doc、 .docx、 .xls、 .ppt)转化为html格式。 二、利用jodconverter(基于OpenOffice服务)将文件( .doc、 .docx、 .xls、 .ppt)转化为pdf格式。 转换成html格式大家都能理解，这样就可以直接在浏览器上查看了，也就实现了在线预览的功能；转换成pdf格式这点，需要用户安装了Adobe Reader XI，这样你会发现把pdf直接拖到浏览器页面可以直接打开预览，这样也就实现了在线预览的功能。 ##将文件转化为html格式或者pdf格式 话不多说，直接上代码。
package com.pdfPreview.util;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;
import java.net.ConnectException;
import java.text.SimpleDateFormat;

* 利用jodconverter(基于OpenOffice服务)将文件(*.doc、*.docx、*.xls、*.ppt)转化为html格式或者pdf格式，
* 使用前请检查OpenOffice服务是否已经开启, OpenOffice进程名称：soffice.exe | soffice.bin
