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：
<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>${year}</w:t> </w:r> <w:r> <w:rPr> <wx:font wx:val="宋体"/> </w:rPr> <w:t>年度工作报告</w:t> </w:r> </w:p>
3. 用代码生成：
import freemarker.template.Configuration; import freemarker.template.Template; import java.io.*; import java.util.HashMap; import java.util.Map; /** * @Class name: CreateDoc * <p/> * Short description on the purpose of the program. * @author : youfeng * @modified : 8/29/11 */ public class CreateDoc { private Configuration configuration = null; public CreateDoc() { configuration = new Configuration(); configuration.setDefaultEncoding("utf-8"); } public void create() throws Exception { Map<String, Object> map = new HashMap<String, Object>(); map.put("date", "2011"); map.put("modifyDate", "2011/8/29"); map.put("modifyUser", "Zhu You Feng"); configuration.setClassForTemplateLoading(this.getClass(), "/docTemplate/"); Template t = configuration.getTemplate("doc1.ftl"); File outFile = new File("D:/outFile.doc"); Writer out = new BufferedWriter(new OutputStreamWriter(new FileOutputStream(outFile))); t.process(map, out); } public static void main(String[] args) throws Exception { new CreateDoc().create(); } }
如果你需要在word中添加图片，那你就在第一步制作模板时，加入一张图片占位，然后打开xml文档，可以看到如下的一片base64编码后的代码：
1 <w:binData w:name="wordml://03000001.png" xml:space="preserve">iVBORw0…(很省略很省略)…CC</w:binData>
只要将base64的代码替换成例如：${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：
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(); } }
import freemarker.cache.TemplateLoader; import freemarker.template.Configuration; import freemarker.template.Template; import freemarker.template.TemplateException; import sun.misc.BASE64Encoder; import java.io.*; import java.util.HashMap; import java.util.Map; public class DocumentGenerator { private Configuration configuration = null; public static void main(String[] args) throws Exception { Map<String, Object> map = new HashMap<String, Object>(); map.put("date", "2012"); map.put("modifyDate", "2011/8/29"); map.put("modifyUser", "Zhu You Feng"); new DocumentGenerator().createDoc("", "D:/outFile2.doc", map); } public DocumentGenerator() { configuration = new Configuration(); configuration.setDefaultEncoding("utf-8"); configuration.setClassicCompatible(true); configuration.setTemplateLoader(new ByteArrayStreamTemplateLoader(new ByteArrayInputStream( getBytesFromFile(new File("D:/ownProject/freemarkerToDoc/src/main/resources/docTemplate/doc1.ftl")) ))); } /** * @param fileName * @param outFileName * @param dataMap */ public void createDoc(String fileName, String outFileName, Map dataMap) { Template t = null; try { t = configuration.getTemplate(fileName); } catch (IOException e) { e.printStackTrace(); } File outFile = new File(outFileName); Writer out = null; try { out = new BufferedWriter(new OutputStreamWriter(new FileOutputStream(outFile))); } catch (FileNotFoundException e1) { e1.printStackTrace(); } try { t.process(dataMap, out); } catch (TemplateException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } } public byte[] getBytesFromFile(File f) { if (f == null) { return null; } try { FileInputStream stream = new FileInputStream(f); ByteArrayOutputStream out = new ByteArrayOutputStream(1000); byte[] b = new byte[1000]; int n; while ((n = stream.read(b)) != -1) out.write(b, 0, n); stream.close(); out.close(); return out.toByteArray(); } catch (IOException e) { e.printStackTrace(); } return null; } } class ByteArrayStreamTemplateLoader implements TemplateLoader { InputStream in = null; public ByteArrayStreamTemplateLoader(ByteArrayInputStream inputStream) { in = inputStream; } public Object findTemplateSource(String name) throws IOException { System.out.println("findTemplateSource"); return in; } public long getLastModified(Object templateSource) { return 0; } public Reader getReader(Object templateSource, String encoding) throws IOException { System.out.println("getReader"); return new InputStreamReader(in); } public void closeTemplateSource(Object templateSource) throws IOException { System.out.println("closeTemplateSource"); if (in != null) { in.close(); } } }
