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。
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!
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
[root@iZ2zeg3etf08f6snef3lgrZ ~]# lsb_release -a LSB Version: :(略) Distributor ID: CentOS Description: CentOS Linux release (略) Release: (略) Codename: Core
下载完毕后,利用ssh工具上传到服务器上!
