这篇文章主要为大家展示了“JAVA中如何使用openoffice将Excel转PDF再转图片功能”，内容简而易懂，条理清晰，希望能够帮助大家解决疑惑，下面让小编带领大家一起研究并学习一下“JAVA中如何使用openoffice将Excel转PDF再转图片功能”这篇文章吧。
需求
公司一个小项目要结尾了, 有非常多的表格, 而且非常复杂, 例如
例如：（这表格, 有想死的心…）
看到这样的表格，第一反应是n脸懵逼，这得做到啥时候啊，最后想到用一个方法，让客户自己玩！！
平台提供Excel模版下载，客户下载填写完再提交Excel，平台再将Excel转PDF，顺便将PDF转成图片，给前端展示，想法简单，方案可行，开工！
方案:
windows server下用 jacob, windows上可完美运行, 但是！！！Linux上不支持jacob！！！（非常重要！！）
poi + iText，貌似不错
openoffice，跨平台
本文选用openoffice，各位看官可自选用iText + poi，自己判别！当然也可以用jacob，前提是你不需要在Linux中运行项目。
安装软件：下载传送门
win：
下载完成后，一路next，最好默认路径安装，免得折腾
完成后 Win + R 填入 Dcomcnfg 打开组件服务
设置openoffice组件服务， 都设成SYSTEM
再设置标识为：交互式用户
进入到安装目录，如果路径是默认的，则在 C:\Program Files (x86)\OpenOffice 4\program 下面，
进到这个路径下，按住 shift 再点击鼠标右键，在此处打开命令窗口，输入 soffice -headless-accept=“socket,host=127.0.0.1,port=8100;urp;”-nofirststartwizard， 查看是否启动成功， 黑窗口输入 netstat -ano
windows下安装完毕！

linux：下载传送门
根据自己的Linux系统选择RPM包或者DEB，如果是Ubuntu则选DEB，其他就选RPM包，查看当前操作系统是ubuntu还是centos
