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>

         </w:r>

         <w:r>

             <w:rPr>

                 <wx:font wx:val="宋体"/>

             </w:rPr>

             <w:t>年度工作报告</w:t>

         </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

11  * Short description on the purpose of the program.

14  */
15 public class CreateDoc {
16 
17     private Configuration configuration = null;
18 
19     public CreateDoc() {
20         configuration = new Configuration();
21         configuration.setDefaultEncoding("utf-8");
22     }
23 
24     public void create() throws Exception {
25         Map<String, Object> map = new HashMap<String, Object>();
26         map.put("date", "2011");
27         map.put("modifyDate", "2011/8/29");
28         map.put("modifyUser", "Zhu You Feng");
29 
30         configuration.setClassForTemplateLoading(this.getClass(), "/docTemplate/");
31         Template t = configuration.getTemplate("doc1.ftl");
32         File outFile = new File("D:/outFile.doc");
33         Writer out = new BufferedWriter(new OutputStreamWriter(new FileOutputStream(outFile)));
34         t.process(map, out);
35     }
36 
37     public static void main(String[] args) throws Exception {
38         new CreateDoc().create();
39 
40     }
41 }

 

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：

 <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：

 <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;
 7 import java.util.Map;

14 public class CreateDocWithImage {
15 
16     private Configuration configuration = null;
17 
18     public CreateDocWithImage() {
19         configuration = new Configuration();
20         configuration.setDefaultEncoding("utf-8");
21     }
22 
23     public void create() throws Exception {
24         Map<String, Object> map = new HashMap<String, Object>();
25         map.put("year", "2011");
26         map.put("person", "Zhu You Feng");
27         map.put("image", getImageStr());
28 
29         configuration.setClassForTemplateLoading(this.getClass(), "/docTemplate/");
30         Template t = configuration.getTemplate("doc2.ftl");
31         File outFile = new File("D:/outFile.doc");
32         Writer out = new BufferedWriter(new OutputStreamWriter(new FileOutputStream(outFile)));
33         t.process(map, out);
34     }
35 
36     private String getImageStr() {

42             data = new byte[in.available()];
43             in.read(data);
44             in.close();
45         } catch (IOException e) {
