这里注意:你还一个需要把一个jar的文件夹(文章最下边有相应的百度云下载地址)你找到自己的maven仓库把对应的jar手动放入到 【repository/org/】目录下,在idea右边导入后会有有红色波浪线警告。整个可忽略,不影响使用
下图是对应怎么找到自己的maven repository路径

windows下(我的是win10)oppenOffice在安装时候一路确定就可以,
在linux我在自己的阿里云Centos7.4上安装linux遇到了一些问题。开始下载的【download language pack】但是在安装过程中会缺少依赖出问题,后来选择了 【download full installation】
1、首先linux上安装需要把下面的安装包下载
2、然后解压 运行命令解压文件:tar -xzvf Apache_OpenOffice_4.1.5_Linux_x86-64_install-rpm_zh-CN.tar.gz
3、然后运行安装命令:cd zh-CN/RPMS/ rpm -ivh *.rpm
四、最后提供大家下载对应的工程demo和对应的jar包,以及oppenoffice下载的安装包
链接:https://pan.baidu.com/s/1RQQgmeSIpEiJVPkKVC2zuw 密码:ttp4
再次注意:maven jar 对应直接解压放入到org目录下,然后刷新maven依赖或者重启ide
最后请大家转文章时不要复制粘贴一部分导致别人看不懂。如果我写的哪里有不懂了直接评论刷一下,看到我会及时回复的。
