#### 7.6 PoiBaseView.render view的補救 假如因為不可抗拒或者其他神奇的原因，view導出無法使用，作者遇到過好幾次了，各種神奇原因都有，提供一個統一的封裝，算是一個補救措施吧 上面的modelMap寫法和設置參數還是一樣，最后直接輸出就可以了 PoiBaseView.render(modelMap, request, response,View名稱); 看個簡單demo ~~~ @RequestMapping("load") public void downloadByPoiBaseView(ModelMap map, HttpServletRequest request, HttpServletResponse response) { List<MsgClient> list = new ArrayList<MsgClient>(); for (int i = 0; i < 100; i++) { MsgClient client = new MsgClient(); client.setBirthday(new Date()); client.setClientName("小明" + i); client.setClientPhone("18797" + i); client.setCreateBy("JueYue"); client.setId("1" + i); client.setRemark("測試" + i); MsgClientGroup group = new MsgClientGroup(); group.setGroupName("測試" + i); client.setGroup(group); list.add(client); } ExportParams params = new ExportParams("2412312", "測試", ExcelType.XSSF); params.setFreezeCol(2); map.put(NormalExcelConstants.DATA_LIST, list); map.put(NormalExcelConstants.CLASS, MsgClient.class); map.put(NormalExcelConstants.PARAMS, params); PoiBaseView.render(map, request, response, NormalExcelConstants.EASYPOI_EXCEL_VIEW); } ~~~
