寫留的商務超市管理系統~~~第一部分

標籤：商超 java

需求請見：http://pan.baidu.com/s/1pJPsYF5

有機會希望再補po到blog上面~

首先用menu把進入後的架構搭起來

/* * 各級菜單顯示 */package com.pb.menu;public class Menu {/** * 登陸菜單 */public void login() {System.out.println("歡迎使用商超管理系統");System.out.println("1、登陸系統");System.out.println("2、退出");}/** * 主菜單內容 */public void mainMenu() {System.out.println("**********我是分割線***********");System.out.println("1、商品維護");System.out.println("2、前台收銀");System.out.println("3、商品管理");System.out.println("4、返回上一級菜單");System.out.println("**********我是分割線***********");}/** * 商品維護菜單內 容 */public void mainMenu_1() {System.out.println("商超購物系統>>>商品維護");System.out.println("**********我是分割線***********");System.out.println("1、增加商品資訊");System.out.println("2、更改商品資訊");System.out.println("3、刪除商品資訊");System.out.println("4、顯示所有商品資訊");System.out.println("5、查詢商品資訊");System.out.println("6、入庫管理");System.out.println("7、儲存");System.out.println("8、返回上一級菜單");System.out.println("**********我是分割線***********");}/** * 前台收銀菜單內容 */public void mainMenu_2() {System.out.println("商超購物系統>>>前台收銀");System.out.println("**********我是分割線***********");System.out.println("1、購物結算");System.out.println("2、返回上一級菜單");System.out.println("**********我是分割線***********");}/** * 商品維護菜單內容 */public void mainMenu_3() {System.out.println("商超購物系統>>>商品管理");System.out.println("**********我是分割線***********");System.out.println("1、設定商品預警庫存");System.out.println("2、今日售出商品");System.out.println("3、售貨員管理");System.out.println("4、返回上一級菜單");System.out.println("**********我是分割線***********");}public void mainMenu_3_3() {System.out.println("商超購物系統>>>商品管理>>>售貨員管理");System.out.println("**********我是分割線***********");System.out.println("1、新增售貨員資訊");System.out.println("2、修改售貨員資訊");System.out.println("3、刪除售貨員資訊");System.out.println("4、顯示所有售貨員資訊");System.out.println("5、查看售貨員資訊");System.out.println("6、儲存");System.out.println("7、返回上一級菜單");System.out.println("**********我是分割線***********");}}

然後我的思路非常線性，寫了寫架構在紙上，大概就是兩個東西，一個叫salesman，用來操作物品，一個叫做good，就是物品。

我用一個叫user的類去管理儲存他們兩個的方法和屬性。然後再分別去管理調用

於是我先把main函數寫出來，然後就每個缺少的部分再去寫他們每個的內容。

然後我們再去寫他們的Management

——————————————————華麗的分割線——————————————————————

/** * 管理售貨員庫 */package com.pb.management;import com.pb.salesman.Salesman;import com.pb.salesmanBiz.SalesmanGroup;public class SalesmanManagement {SalesmanGroup sg = new SalesmanGroup();// 新增售貨員public void add(Salesman user) {sg.add(user);}// 修改售貨員public void modity(Salesman user) {sg.modify(user);}// 刪除售貨員public void delete(String name) {sg.delete(name);}// 尋找指定售貨員public void query(String name) {sg.query(name);}// 尋找全部售貨員public void queryAll() {sg.queryAll();}//儲存public void save(){sg.save();}}

先寫到這裡，具體的底層操作請見下一步！
