一、前臺頁面其實就是一個檔案的上傳的模板

後臺的controller
/** * 批量匯入 */ @RequestMapping("/addbatch") @ApiOperation(value = "批量匯入人員資訊", httpMethod = "POST", consumes="application/json;charset=UFT-8",produces="application/json;charset=UFT-8", notes = "批量匯入人員資訊") public Map<String, Object> addbatch(@ApiParam(name="file",value="檔案",required=true) MultipartFile file){ Map<String, Object> map = new HashMap<String, Object>(); String result = manager.readExcelFile(file); map.put("message", result); return map; }
service層
@SuppressWarnings("unused") public String readExcelFile(MultipartFile file) { // TODO Auto-generated method stub String result = ""; //建立處理EXCEL的類 ReadExcel readExcel = new ReadExcel(); //解析excel，獲取上傳的事件單 List<Map<String, Object>> beExamList = readExcel.getExcelInfo(file); //至此已經將excel中的資料轉換到list裡面了,接下來就可以操作list,可以進行儲存到資料庫,或者其他操作, for(Map<String, Object> modal:beExamList){ SatBeExam entity = new SatBeExam(); entity.setCommunity((String)modal.get("community")); entity.setName((String)modal.get("name")); entity.setPhone((String)modal.get("phone")); entity.setStreet((String)modal.get("street")); entity.setDept_name((String)modal.get("dept_name")); entity.setIdcard((String)modal.get("idcard")); entity.setRemark((String)modal.get("remark")); entity.setDept_id((String)modal.get("dept_id")); if(entity != null){ dao.save(entity); result = "插入資料庫成功"; }else{ result = "插入資料庫是失敗"; } } return result; }
dao層就不往出貼了
還有一個相當於工具的方法

到此，匯入完成。
