java freemark导出word （模板、单张图片、多张图片源码）

• 首先模板设置
• 代码编辑
• 设置word只读、全部
• 环境设置、jar包

---

模板设置

**
设置模板然后另存为

这里一定要选择对xml格式，否则后期模板图片设置的时候有问题，无法多张图片，被这坑过，勿踩！！！

然后就是把xml文件直接修改后缀.ftl文件直接放到项目目录下

代码：

ftl模板修改

通过w:tr搜索找到换行处添加
<#list list as test>
里面的值要用test.name代替 如果是一个就不用了后台代码封装就是一个list 不是map就不用
如果是map

列表循环

多张图片

多张图片一定要切记找到如图然后增加
src=”${“wordml://0300000”+qy_index+1+”.png”}”
这里设置成变量 否则freemark只显示第一张图片

<#list wryList as qy>

${qy.image}
