javadocx4j动态⽣成表格，保存为word，并通过Libreoffice转PDF
缘起
最近客户要求把业务字段⽣成⼀个pdf，包含⼤量的表格，于是探究了两天版，终于出⼀个⽐较完美的解决⽅案。本次采⽤的是
docx4j，Libreoffice两个套件，docx4j本⾝有转PDF的功能，但是转换完成的PDF乱码，我没有到解决乱码的⽅法（⽐较菜，勿喷），然后选择了Libreoffice的⽅式，期间也是解决了很多bug，然后最终成功
安装 Libreoffice
之前在⽹上看到也有使⽤openoffice的，我之前也试过，转成pdf格式全变了，尤其是表格，后来发现的兼容性更好的Libreoffice，下⾯开始安装。
1. 官⽹地址：
2. 点击download，然后选择系统，我的是win10 64位的，所以选择Windows x86_64
3. 点下载后开始下载，如果感觉下载⽐较慢，在chrome（我使⽤的是⾕歌浏览器）的下载内容⾥⾯，复制下载链接，拷贝到迅雷⾥⾯，
我就是⽤的这种⽅法，下载速度还不错
4. 下载下来是msi⽂件，开始安装，我⾃定义了⾃⼰的路径：D:\libreOffice6\program\soffice -headless --
accept="socket,host=127.0.0.1,port=8100;urp;" -nologo -nofirststartwizard，host如果是127.0.0.1的话是只能本机访问，要是想让所有机器都能访问，就改为0.0.0.0，port是端⼝号。记住⼀定要加 -handless这个参数，不然在windows下调试⼀定会没法退出程序，这个参数的意思就是⽆界⾯运⾏。
