1、pom檔案加入，此處目前測試3.0.3版本可以無bug，3.2.0不行

2、

編寫實體類

• 此處注意必須要有空建構函式，否則會報錯“物件建立錯誤”

• 關於註解@Excel，其他還有@ExcelCollection，@ExcelEntity ，@ExcelIgnore，@ExcelTarget等，此處我們用不到，可以去官方檢視更多

3、實體類

2.5 Map匯入,自由發揮

這天,老師把路飛叫到辦公室,總是被叫,能者的悲哀啊,讓他臨時匯入一批資料,到資料庫,但是中間需要處理一些欄位邏輯沒辦法直接匯入到資料庫, 這時路飛首先想到構造一個bean然後標記註解,匯入處理物件,但是想想一次的物件太過於浪費,不如用map試試,獲取map處理map也是一樣的 匯入的邏輯就變成了

        ImportParams params = new ImportParams();
        long start = new Date().getTime();
        List<Map<String, Object>> list = ExcelImportUtil.importExcel(
            new File(PoiPublicUtil.getWebRootPath("import/check.xls")), Map.class, params);

匯入後,處理每個map,然後入庫完美的解決了老師的需求,簡單更快捷,和bean匯入基礎沒有區別,省去了bean的構造時間
