解决方案：把application.properties中的office.home 改为自己安装libreoffice的地址

2、预览文件乱码

下载如下字体包 http://kkfileview.keking.cn/fonts.zip

解压至 /usr/share/fonts 目录下

依次执行 mkfontscale 、mkfontdir 、fc-cache 使字体生效

为使系统所有用户都能使用该字体，需要给字体访问权限，进入解压后的目录，执行命令：

● chmod -R 755 *.TTF

● chmod -R 755 *.ttf

● chmod -R 755 *.ttc

重启系统 或者 source /etc/profile

重启服务后正常
