1. 用word写一个需要导出的word模板，然后存为xml格式。
2. 将xml中需要动态修改内容的地方，换成freemarker的标识符，例如：

添加图片
如果你需要在word中添加图片，那你就在第一步制作模板时，加入一张图片占位，然后打开xml文档，可以看到如下的一片base64编码后的代码：
1
<
w:binData
w:name
="wordml://03000001.png"
xml:space
="preserve"
>
iVBORw0…(很省略很省略)…CC
</
w:binData
>
只要将base64的代码替换成例如：${image}，如下：
1
<
w:binData
w:name
="wordml://03000001.png"
xml:space
="preserve"
>
${image}
</
w:binData
>
这里要注意“>${image}<”这尖括号中间不能加任何其他的诸如空格，tab，换行等符号。
然后用代码生成：
