velocity根据模板导出word并下载工具方法

maven pom文件引入jar

<!-- velocity -->
<dependency>
    <groupId>org.apache.velocity</groupId>
    <artifactId>velocity</artifactId>
</dependency>
<dependency>
    <groupId>org.apache.velocity</groupId>
    <artifactId>velocity-tools</artifactId>
</dependency>

版本号，任意

导出方法如下

/**
  * 导出word并下载
  *
  * @author wangdongdong
  * 
  * @param response
  * @param request
  * @param params 传入的参数map
  * @param fileName  生成的文件名
  * @param templateFileName   模板文件名
  */
 public static void exportToWordDownload(HttpServletResponse response, HttpServletRequest request, Map<String, Object> params, String fileName, String templateFileName) {

     OutputStream outputStream = null;
     try {

         WebApplicationContext ctx = RequestContextUtils.getWebApplicationContext(request);
         String webRoot = ctx.getServletContext().getRealPath("/");

	// 获取绝对路径
         String filePath = webRoot + File.separator + "WEB-INF" + File.separator + "template" + File.separator;
         outputStream = response.getOutputStream();
         response.reset();
	// 防止文件名乱码
         String agent = request.getHeader("USER-AGENT");
         if (agent.indexOf("MSIE") >= 0) {
             URLCodec codec = new URLCodec();
             fileName = codec.encode(fileName, "UTF-8");
             fileName = StringUtils.replace(fileName, "+", "%20");
         } else {
             fileName = new String(fileName.getBytes("UTF-8"), "ISO-8859-1");
         }

         response.setHeader("Content-disposition", "attachment; filename=\"" + fileName + "\"");
         response.setContentType("application/x-msdownload");

         createDocAndDownload(params, filePath, templateFileName, outputStream);

     } catch (Exception ex) {
         logger.error(ex.getMessage());
     } finally {
         IOUtils.closeQuietly(outputStream);
     }
 }

 /**
  * 生成word并下载
  * @param dataMap
  * @param templatePath
  * @param templateFileName
  * @param os
  * @throws Exception
  */
 private static void createDocAndDownload(Map<String, Object> dataMap, String templatePath, String templateFileName, OutputStream os)
throws Exception {
     VelocityContext velocityContext = new VelocityContext();
     for (String key : dataMap.keySet()) {
         velocityContext.put(key, dataMap.get(key));
     }
     // 设置路径参数
     Properties properties = new Properties();
     // 这是模板所在路径
     properties.setProperty(VelocityEngine.FILE_RESOURCE_LOADER_PATH, templatePath);
     VelocityEngine velocityEngine = new VelocityEngine();
     // 初始化
     velocityEngine.init(properties);
     velocityEngine.init();
     // 加载模板
     Template template = velocityEngine.getTemplate(templateFileName, "UTF-8");
     BufferedWriter writer = new BufferedWriter(new OutputStreamWriter(os, "utf-8"));
     template.merge(velocityContext, writer);
     writer.flush();
 }

将制作好的word模板，另存为xml格式的文件

打开，将需要替换的文字，改用传入的对象字段

调用方法,并且将map里面放入doctorName

exportToWordDownload()

生成如下文件：
