java使⽤freemarker完美导出word⽂档（带图）
poi
java2word
freemarker
最后选⽤freemarker，为什么呢？业务需要。
⽣成doc格式，⽐较简单，这⾥就不列举了，⽹上有⼤量的例⼦
⽣成思路⼤概就是保存⼀个doc⽂件，改后缀位xml，占位符去渲染。其中图⽚转换成base64格式。
这⾥主要讲docx格式。测试环境office 2013 2016
特殊符号需要转义，否则报错
docx格式本质上是个zip压缩包。
1. 新建docx⽂件，插⼊⾃⼰需要的格式，如图
2. 修改后缀为zip
[Content_Types].xml
如果需要插图，需要修改此⽂件，这⾥以jpg图⽚为例，
插⼊图⽚word转为jpeg，建议图⽚修改jpg为jepg
如果插⼊其他格式在此⽂件夹添加对应的说明
3.打开word⽂件夹，主要改动也是在这⾥
注意： <pic:cNvPr id=“1” name=“图⽚ 1”/> 中的id最好使⽤数字，前⾯使⽤的字符串出现打开⽂件弹错误的情况=====================================================================

freemarker相关配置
这⾥就不啰嗦了
