添加圖片
如果你需要在word中添加圖片，那你就在第一步制作模板時，加入一張圖片占位，然后打開xml文檔，可以看到如下的一片base64編碼后的代碼：
 

1 <w:binData w:name="wordml://03000001.png" xml:space="preserve">iVBORw0…(很省略很省略)…CC</w:binData></div>
</div>
</span> 
只要將base64的代碼替換成例如：${image}，如下：
 

1 <w:binData w:name="wordml://03000001.png" xml:space="preserve">${image}</w:binData></div>
</div>
</span> 
這里要注意“>${image}<”這尖括號中間不能加任何其他的諸如空格，tab，換行等符號。
然后用代碼生成：

import freemarker.template.Template;
import sun.misc.BASE64Encoder;

import java.io.*;
import java.util.HashMap;
import java.util.Map;

}
public void create() throws Exception {

 Map<String, Object> map = new HashMap<String, Object>();
 map.put("year", "2011");
 map.put("person", "Zhu You Feng");
 map.put("image", getImageStr());

 configuration.setClassForTemplateLoading(this.getClass(), "/docTemplate/");
 Template t = configuration.getTemplate("doc2.ftl");
 File outFile = new File("D:/outFile.doc");
 Writer out = new BufferedWriter(new OutputStreamWriter(new FileOutputStream(outFile)));
 t.process(map, out);
