java freemark导出word （模板、单张图片、多张图片源码）

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：

import java.io.File;

import java.io.FileInputStream;

import java.io.FileNotFoundException;

import java.io.FileOutputStream;

import java.io.IOException;

InputStream in = null;

byte[] data = null;

try {

data = new byte[in.available()];

in.read(data);

in.close();

e.printStackTrace();

}

BASE64Encoder encoder = new BASE64Encoder();

return encoder.encode(data);

}

}

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}
