匯出程式碼如下:

public void freeMarkerDownTest(HttpServletResponse response, HttpServletRequest request)
			throws UnsupportedEncodingException {
		List<Map<String, Object>> list = new ArrayList<Map<String, Object>>();
		Map<String, Object> map = null;
		for (int i = 1; i < 10; i++) {
			map = new HashMap<String, Object>();
			map.put("dx", i);
			map.put("class", i + "班");
			map.put("d1", i + "1%");
			map.put("d2", i + "2%");
			map.put("d3", i + "3%");
			map.put("d4", i + "4%");
			map.put("d5", i + "5%");
			map.put("d6", i + "6%");
			map.put("d7", i + "7%");
			map.put("d8", i + "8%");
			list.add(map);
		}
		Map<String, Object> testMap = new HashMap<String, Object>();
		testMap.put("datas", list);
		Configuration configuration = new Configuration();
		FreeMarkerUtil handler = new FreeMarkerUtil(configuration);
		response.setContentType("application/octet-stream;charset=utf-8");
		String fileName = FileControl.encodeFileName(request, "2017-10-23 -學校考勤報表.xls");
		response.setHeader("Content-Disposition", "attachment;" + fileName);
		try {
			String templatePath = "E:/zlsu/Document/marking/framktodoc/";
			handler.write(templatePath, "freemark測試1.xml", testMap, response.getWriter());
			System.out.println("匯出成功！");
		} catch (Exception e) {
			e.printStackTrace();
		}

	}
 

匯出完用WPS 開啟正常 用EXCEL2016 打開出現檔案錯誤如下:

解決方法：

 用OpenOffice.org 3.4.1 開啟EXCEL 檔案 然後把它 用Oppenoffice 另存為XML, 然後插入對應的 freemarker 指令 把這個 xml檔案作為 匯出的模板， 匯出的excel 就能用

EXCEL2016 打開了如下圖:
