Java通过FreeMarker模板生成Word文件
1、引用依赖
compile('org.freemarker:freemarker:2.3.20')
2、制作Word文件
新建word文件，调整内容和格式，需要动态传参的地方使用占位符，如图：
3、Word文件转换为模板
打开Word文件，另存为，XML格式文件，如图：
4、编写工具类

总结：
调用工具类的时，动态传参；
工具类中包含直接下载、生成word文件到服务器指定路径，两种方式。
模板参数Map中可传入list，进入模板中循环展示，可进行 list循环、if判断、获取长度下标等：
<#list details as d>
<#if (details?size != d_index+1)>、<#else>。
