用 Freemarker 生成 word 文档



阅读目录

• 添加图片
• 自定义载入模板

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 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16

<w:p wsp:rsidR="00D02906" wsp:rsidRDefault="00FA4C58" wsp:rsidP="00FA4C58">          <w:pPr>              <w:jc w:val="center"/>              <w:rPr>                  <w:rFonts w:hint="fareast"/>              </w:rPr>          </w:pPr>          <w:r>              <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><span style="line-height:22px;font-family:'Courier New';" class="Apple-style-span"><span style="color:#0000ff;"></</span><span style="color:#800000;">w:p</span><span style="color:#0000ff;">></span></span>

3.       用代码生成：

import freemarker.template.Configuration;  import freemarker.template.Template;     import java.io.*;  import java.util.HashMap;  import java.util.Map;     /**   * @Class name:    CreateDoc   * <p/>   * Short description on the purpose of the program.   * @author : youfeng   * @modified : 8/29/11   */  public class CreateDoc {         private Configuration configuration = null;         public CreateDoc() {          configuration = new Configuration();          configuration.setDefaultEncoding("utf-8");      }         public void create() throws Exception {          Map<String, Object> map = new HashMap<String, Object>();          map.put("date", "2011");          map.put("modifyDate", "2011/8/29");          map.put("modifyUser", "Zhu You Feng");             configuration.setClassForTemplateLoading(this.getClass(), "/docTemplate/");          Template t = configuration.getTemplate("doc1.ftl");          File outFile = new File("D:/outFile.doc");          Writer out = new BufferedWriter(new OutputStreamWriter(new FileOutputStream(outFile)));          t.process(map, out);      }         public static void main(String[] args) throws Exception {          new CreateDoc().create();         }  }

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：
