用 Freemarker 生成 word 文档.doc

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： $year 年度工作报告 3.用代码生成：import freemarker.template.Configuration; import freemarker.template.Template; import java.io.*; import java.util.HashMap; import java.util.Map; /* * Class name: CreateDoc * * Short description on the purpose of the program. * author : youfeng * modified : 8/29/11 */ public class CreateDoc private Configuration configuration = null; public CreateDoc() configuration = new Configuration(); configuration.setDefaultEncoding(utf-8); public void create() throws Exception Map map = new HashMap(); map.put(date, 2011); map.put(modifyDate, 2011/8/29); map.put(modifyUser, Zhu You Feng); configuration.setClassForTemplateLoading(this.getClass(), /docTemplate/); Template t = configuration.getTemplate(doc1.ftl); File outFile = new File(D:/outFile.doc); Writer out = new BufferedWriter(new OutputStreamWriter(new FileOutputStream(outFile); cess(map, out); public static void main(String args) throws Exception new CreateDoc().create(); 添加图片如果你需要在word中添加图片，那你就在第一步制作模板时，加入一张图片占位，然后打开xml文档，可以看到如下的一片base64编码后的代码：1iVBORw0(很省略很省略)CC只要将base64的代码替换成例如：$image，如下：1$image这里要注意“$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 map = new HashMap(); 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); cess(map, out); private String getImageStr() String imgFile = d:/test.jpg; InputStream in = null; byte data = null; try in = new FileInputStream(imgFile); data = new bytein.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(); 自定义载入模板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 map = new HashMap(); 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 cess(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 byte1000; 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,
