用 Freemarker 生成 word 文档
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：
1 <w:p wsp:rsidR="00D02906" wsp:rsidRDefault="00FA4C58" wsp:rsidP="00FA4C58">
2 <w:pPr>
3 <w:jc w:val="center"/>
4 <w:rPr>
5 <w:rFonts w:hint="fareast"/>
6 </w:rPr>
7 </w:pPr>
8 <w:r>
9 <w:t>${year}</w:t>
10 </w:r>
11 <w:r>
12 <w:rPr>
13 <wx:font wx:val="宋体"/>
14 </w:rPr>
15 <w:t>年度工作报告</w:t>
16 </w:r>
2 <w:pPr>
3 <w:jc w:val="center"/>
4 <w:rPr>
5 <w:rFonts w:hint="fareast"/>
6 </w:rPr>
7 </w:pPr>
8 <w:r>
9 <w:t>${year}</w:t>
10 </w:r>
11 <w:r>
12 <w:rPr>
13 <wx:font wx:val="宋体"/>
14 </w:rPr>
15 <w:t>年度工作报告</w:t>
16 </w:r>
17 </w:p>
3. 用代码生成： 1 import freemarker.template.Configuration;
2 import freemarker.template.Template;
3
4 import java.io.*;
5 import java.util.HashMap;
6 import java.util.Map;
7

17 private Configuration configuration = null;
18
19 public CreateDoc() {
20 configuration = new Configuration();
21 configuration.setDefaultEncoding("utf-8");
22 }

30 configuration.setClassForTemplateLoading(this.getClass(), "/docTemplate/");
31 Template t = configuration.getTemplate("doc1.ftl");

33 Writer out = new BufferedWriter(new OutputStreamWriter(new FileOutputStream(outFile)));
34 t.process(map, out);

37 public static void main(String[] args) throws Exception {

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：
1 import freemarker.template.Configuration;
2 import freemarker.template.Template;
3 import sun.misc.BASE64Encoder;
4
5 import java.io.*;
6 import java.util.HashMap;
