1. 准备好模板，并调整好模板中的格式

2. 将word文档另存为Word 2003 XML格式

3. 更改模板后缀xml为ftl

4. 使用freemarker标签替换数据

5. 获取模板代码

   java">private static Configuration configuration = null; 
   private static Map<String, Template> allTemplates = null;
   static { 
         configuration = new Configuration(); 
         configuration.setDefaultEncoding("utf-8"); 
         configuration.setClassForTemplateLoading(WordGenerator.class, "/download"); 
         allTemplates = new HashMap<String, Template>();
         try { 
             // 模板 
             Template recordTemplates = configuration.getTemplate( "test.ftl", "UTF-8"); 
             allTemplates.put("template", recordTemplates); 
         } catch (IOException e) { 
             e.printStackTrace(); 
             throw new RuntimeException(e); 
         } 
   }

    

6. 生成word代码

   java">public static File createDoc(Map<?, ?> dataMap, String type, String tempFileDir) { 
       // 临时文件名称 
       String name = "temp" + (int) (Math.random() * 100000) + ".doc"; 
       File fileMkDir = new File(tempFileDir); 
       // 如果文件夹不存在则创建 
       if (!fileMkDir.exists() && !fileMkDir.isDirectory()) { 
           fileMkDir.mkdir(); 
       } 
       File file = new File(tempFileDir, name); 
       // 获取模板 
       Template template = allTemplates.get(type); 
       try { 
            Writer out = null; 
            FileOutputStream fos = null; 
            fos = new FileOutputStream(file); 
            OutputStreamWriter writer = new OutputStreamWriter(fos, "UTF-8"); 
            out = new BufferedWriter(writer); 
            template.process(dataMap, out); 
            out.flush(); 
            out.close(); 
       } catch (Exception ex) { 
            ex.printStackTrace(); 
            throw new RuntimeException(ex); 
       } 
       return file; 
   }

    

注： 1.若导出内容包含图片，需将图片转为base64编码

java">public static String getBase64ImgStrLocal(String imgFile) {
		// 将图片文件转化为字节数组字符串，并对其进行Base64编码处理
		if (imgFile == null || imgFile == "") {
			return "";
		}
		File tempFile = new File(imgFile);
		if (!tempFile.exists() || !tempFile.isFile()) {
			return "";
		}

		InputStream in = null;
		byte[] data = null;
		// 读取图片字节数组
		try {
			in = new FileInputStream(tempFile.getAbsolutePath());
			data = new byte[in.available()];
			in.read(data);
			in.close();
		} catch (IOException e) {
			e.printStackTrace();
		}
		BASE64Encoder encoder = new BASE64Encoder();
		// String returnData = new String(Base64.encodeBase64(data));
		String returnData = encoder.encode(data);
		return returnData == null ? "" : returnData;
	}

        2.导出的word中包含特殊字符需进行替换：

        
        导出字段为null需替换成""，使用freemarker标签：${content!''}或${((content)!'')?html}(可替换特殊字符)

7.设置以浏览器的方式进行下载：

java">@RequestMapping("/export") 
@ResponseBody 
public void export(HttpServletRequest request,HttpServletResponse response) { 
     File file = null; 
     InputStream fin = null; 
     ServletOutputStream out = null; 
     try { 
         request.setCharacterEncoding("utf-8"); 
         //获取数据**** 
         Map<String,Object> map = ************** /
         /获取数据***** 
         file = WordGenerator.createDoc(map, "template", tmpStore); 
         fin = new FileInputStream(file); 
         String filename = "导出的word文件名"; 
         response.setCharacterEncoding("utf-8"); 
         response.setContentType("application/msword"); 
         // 设置浏览器以下载的方式处理该文件 
         filename = new String(filename.getBytes("gb2312"), "ISO8859-1"); 
         response.addHeader("Content-Disposition", "attachment;filename=" + """ + 
               filename + ".doc"); 
         out = response.getOutputStream(); 
         byte[] buffer = new byte[512]; 
         // 缓冲区 
         int bytesToRead = -1; 
         // 通过循环将读入的Word文件的内容输出到浏览器中 
         while ((bytesToRead = fin.read(buffer)) != -1) { 
                out.write(buffer, 0, bytesToRead); 
         } 
      } finally { 
         if (fin != null) { 
              fin.close(); 
         } if (out != null) { 
              out.close(); 
         } if (file != null) { 
               file.delete(); // 删除临时文件 
         } 
   }
