• 添加圖片
• 自定義載入模板

1.?????? 用word寫一個需要導出的word模板，然后存為xml格式。

2.?????? 將xml中需要動態修改內容的地方，換成freemarker的標識符，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="宋體"/> ?????????????</w:rPr> ?????????????<w:t>年度工作報告</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.?????? 用代碼生成： ?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41

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>

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>

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：

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56

import freemarker.template.Configuration; ?import freemarker.template.Template; ?import sun.misc.BASE64Encoder; ?? ?import java.io.*; ?import java.util.HashMap; ?import java.util.Map; ?? ?/** ??* @Class name:??? CreateDoc ??* @author: youfeng ??* @modified: 8/29/11 ??*/ ?public class CreateDocWithImage { ?? ?????private Configuration configuration = null; ?? ?????public CreateDocWithImage() { ?????????configuration = new Configuration(); ?????????configuration.setDefaultEncoding("utf-8"); ?????} ?? ?????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); ?????} ?? ?????private String getImageStr() { ?????????String imgFile = "d:/test.jpg"; ?????????InputStream in = null; ?????????byte[] data = null; ?????????try { ?????????????in = new FileInputStream(imgFile); ?????????????data = new byte[in.available()]; ?????????????in.read(data); ?????????????in.close(); ?????????} catch (IOException e) { ?????????????e.printStackTrace(); ?????????} ?????????BASE64Encoder encoder = new BASE64Encoder(); ?????????return encoder.encode(data); ?????} ?? ?????public static void main(String[] args) throws Exception { ?????????new CreateDocWithImage().create(); ?? ?????} ?}
