背景：跟着我的步骤一步一步，最后一定会成功！！
首先生成pdf有很多种方式：
- iText，生成PDF文档，还支持将XML、Html文件转化为PDF文件；
- Apache PDFBox，生成、合并PDF文档；
- docx4j，生成docx、pptx、xlsx文档，支持转换为PDF格式。
比较：
- iText开源协议为AGPL，而其他两个框架协议均为Apache License v2.0。需要用画笔去花模板，很繁琐！
- Apache PDFBox，生成、合并PDF文档；
- docx4j，生成docx、pptx、xlsx文档，支持转换为PDF格式。
本文使用最后一种，思路如下图：
步骤
1.首先将你要生成的pdf，用worl画出来，比如你需要特定结构的pdf，你没办法做到，但是一个wold你可以通过编辑，得到你想要的模板 。如下：（你想要替换的内容换成${arg0!""},就是用将来你需要替换的数据暂时用变量表示出来，后续只要替换变量的值即可！而模板本身不变）
2.其次将word的字体换成宋体（通用），文件另存为xml格式文件如下：
3.将文件改名，以.ftl形式结尾（利用freemarker，所以改成freemarker文件形式）
4.读取ftl文件，将其转化成xml字符串。读取xml字符串，将其转换成word，读取word，利用dom4j将其转换成你想要的模式的pdf
