ssm之九 批量导入excel到数据库
小編覺得挺不錯的,現在分享給大家,幫大家做個參考.
JAVA就業套餐課：https://edu.csdn.net/combo/detail/1230
本案例承接以前的SSM整合系列，針對Oracle中的Dept表做操作，如果單擊瀏覽，則進行批量導入；單擊2則是單個導入。

服務層Service的代碼:

/*** 部門添加*/public void add(Dept dept) {// TODO Auto-generated method stubdao.add(dept);// System.out.println(1/0);}
擴展篇，該段示例代碼只能實現，批量導入dept表中的數據到數據庫，如何實現批量如何多個表呢？
