一、實驗思路

在數據庫中建立兩個表，flow表存放出入庫的單據，Warehouse表存放商品的信息。FlowBean類和WarehouseBean類處理所用到的變量；通過FlowDao類和WarehouseDao類進行連接；通com.servlet包中的類進行增刪改查的操作.

結構及數據庫表如下圖所示：

四、遇到的問題

今天連接數據庫時總是提示client dose not support authentication protocol requested by server;consider upgrading mysql client

後來通過cmd黑框修改了密碼的格式SET PASSWORD FOR -> ‘root‘@‘localhost‘ = OLD_PASSWORD(‘11111‘);問題得到解決；

連接數據庫時出現No suitable driver found for jdbc:sql://localhost:3307/choose?useSSL=false錯誤。後來通過查詢在數據庫後面加上了

?characterEncoding=utf8&useSSL=true一行代碼解決了此問題。
