庫存物資管理系統程式碼，詳細過程和總結
阿新 • • 發佈：2018-12-14
庫存物資管理系統實驗要求如下：
1.背景資料
1、有一個存放商品的倉庫，每天都有商品出庫和入庫。
2、每種商品都有名稱、生產廠家、型號、規格等。
3、出入庫時必須填寫出入庫單據，單據包括商品名稱、生產廠家、型號、
規格、數量、日期、時間、入庫單位（或出庫單位）名稱、送貨（或提貨）人
姓名。
2.系統要求與功能設計
2.1頁面要求
（1）能夠在Tomcat伺服器中正確部署，並通過瀏覽器檢視；（1分）
（2）網站頁面整體風格統一；
2.2設計要求
1、設計出入庫單據的錄入。
2、實現按商品名稱、出入庫日期的查詢。 3.評分標準：
1、A類：完全實現上述功能，達到A類標準的同學可以免於參加期末上機考試，
期末上機考試成績按滿分計算。
2、B類：實現出入庫單據記錄的新增。
3、C類：實現資料庫的連線。
4、D類：不滿足上述要求的。

詳細過程：1.剛拿到題目，覺得貌似比上次的簡單，因為看題目要求的篇幅並不多，但看完題後，思考編寫的過程發現並不簡單，題目能給的關鍵資訊點太少；
2.首先編寫必要的jsp介面，自己懶得寫，是課前在網上見過的類似介面程式碼修改而成的，想省下點時間寫關鍵的方法程式碼；
3.商品資訊的錄入和查詢通過上次實驗的學習已經基本掌握了，但是也費了半天時間弄，主要是不太熟悉，有些東西也是修改程式碼完成的；
4.接下來就是最頭疼的那個出庫，有點懵，我一開始想是不是還用考慮往外取物資的系統，瞎編了半天沒結果，馬上就快下機了，然後聽說是沒那麼複雜，就是相當於上次學生管理系統的修改步驟，想著A標已經無妄了，就回宿舍參考了上次的那個系統又改了快一個多小時，終於磕磕巴巴的做出了個粗糙的程式。
總結：上次靠學長的程式碼完完全全的實現了功能，覺得下一次做系統應該差不多了，沒想到只是按照人家的思路可以做下來，自己做一個新的系統，一些類似的死的東西道是沒問題，出了個出庫就直接懵了，還是缺乏自己的獨立思考，不過這次就是同學提醒了一下思路就自己完成了，還算有進步了，時間花費比較多，以後要加快速度。
