java 实训课程设计：仓库管理系统

大二期末的实训，共有十五个课设可以选择，博主选择的是仓库管理系统。

 文章来源地址https://www.toymoban.com/news/detail-768928.html

这是整个系统的设计模块图（仓库有很多种，博主做的是快递超市仓库管理系统）

不多说，上代码

货物类Cargo:

public class Cargo{
    String name;
    int id;
    String type;
    String source;
    int picking;
    String state;
    int weight;
    String time;

    public Cargo(String name,int id,String type,String source,int picking,int weight) {
        this.name=name;
        this.id =id;
        this.type =type;
        this.source =source;
        this.picking=picking;
        this.state="正常";
        this.weight=weight;
        this.time= null;
    }
    public String getSource() {
        return source;
    }
    public String getName() {
        return name;
    }
    public int getId() {
        return id;
    }
    public String getType() {
        return type;
    }
    public int getPicking(){
        return picking;
    }
    public String getState(){
        return state;
    }
    public int getWeight(){
        return weight;
    }
    public String getTime() {return time;}

    public void setName(String name) {
        this.name = name;
    }

    public void setType(String type) {
        this.type = type;
    }

    public void setSource(String source) {
        this.source = source;
    }

    public void setPicking(int picking) {
        this.picking = picking;
    }

    public void setState(String state) { this.state = state; }

    public void setWeight(int weight) {this.weight = weight;}

    public void setTime(String time) {this.time = time;}

    @Override
    public String toString() {
        return "Cargo{" +
                "name='" + name + '\'' +
                ", id=" + id +
                ", type='" + type + '\'' +
                ", source='" + source + '\'' +
                ", picking='" + picking + '\'' +
                ", state='" + state + '\'' +
                ", weight=" + weight +
                ", time=" + time +
                '}';
    }
}

仓库类Warehouse:

import java.text.SimpleDateFormat;
import java.util.Collection;
import java.util.Date;
import java.util.HashMap;
public class Warehouse{
    private HashMap<Integer, Cargo> cargos = new HashMap<>();
    private int capacity = 0;


    public int getInventory() {
        int inventory = 0;
        for(Cargo cargo : cargos.values()){
            inventory +=cargo.getWeight();
        }
        return inventory;
    }

    public String getNewTime(){
        SimpleDateFormat sdf= new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
        Date date = new Date();
        String str =sdf.format(date);
        return str;
    }
    public int getCapacity() {
        return capacity;
    }
    public void setCapacity(int capacity) {
        this.capacity = capacity;
    }

    public  boolean addCargo(Cargo cargo) {
        if(getInventory()+cargo.getWeight()<=capacity) {
            cargos.put(cargo.getId(), cargo);
            cargo.setTime(getNewTime());
            return true;
        } else {
            return false;
        }
    }
    public boolean getCargo(int id){
        return cargos.get(id) != null;
    }
    public boolean removeCargo(int id){
        return cargos.remove(id) != null;
    }

    public int getCargoPicking(int id){
        Cargo cargo = cargos.get(id);
        return cargo.getPicking();
    }
    public Cargo seekCargo(int id){
        return cargos.get(id);
    }
    public boolean stateChange(int id){
        Cargo cargo = cargos.get(id);
        if(cargo != null) {
            cargo.setState("已报废");
            return true;
        }else {
            return false;
        }
    }
    public WarehouseWarning warning(int capacity){
        if(getInventory() < 0.1 * capacity){
            return WarehouseWarning.EMPTY;
        } else if (getInventory() > 0.9 * capacity) {
            return WarehouseWarning.FULL;
        }else{
            return WarehouseWarning.NONE;
        }
    }

    public Collection<Cargo> getCargos() {
        return cargos.values();
    }

    @Override
    public String toString() {
         String str = "";
         for (Cargo cargo : cargos.values()) {
             str += cargo.getName() + "\n";
         }
         return str;
    }
}

仓库类中用到的枚举WarehouseWarning

public enum WarehouseWarning {
    EMPTY,
    FULL,
    NONE
}

以上为该系统的数据层

由于高级要求中有一条界面友好的要求，博主是用GUI来实现的表现层（另一个高级要求没有完成）

下面是GUI的主界面MainFrame:

        Panel jPanel = new Panel();
        JLabel jLabel1 = new JLabel("货物名字" +":   " + cargo.getName());
        JLabel jLabel2 = new JLabel("编号" +":   " + cargo.getId() + "            ");

提示信息弹窗界面determine：

import javax.swing.*;
import java.awt.*;

public class determine extends JDialog {
    public determine(String str) {
        setVisible(true);
        setBounds(600, 400, 200, 100);
        Container container = getContentPane();
        container.setLayout(null);
        JLabel jLabel = new JLabel(str);
        jLabel.setSize(130, 30);
        container.add(jLabel);
    }
}

最后是主函数Delivery(添加了一些测试用例）

public class Delivery {
    public static void main(String[] args) {
        Warehouse warehouse = new Warehouse();
        warehouse.setCapacity(1000);
//        Cargo cargo1 = new Cargo("康师傅",1,"食品","京东",114514,1);
//        Cargo cargo2 = new Cargo("洗发水",2,"生活用品","淘宝",114514,1);
//        Cargo cargo3 = new Cargo("洗手液",3,"生活用品","淘宝",114514,960);
//        Cargo cargo4 = new Cargo("餐巾纸",4,"生活用品","淘宝",114514,2);
//        Cargo cargo5 = new Cargo("面包",5,"食品","京东",114514,1);
//        Cargo cargo6 = new Cargo("面包",6,"食品","京东",114514,1);
//        Cargo cargo7 = new Cargo("康师傅",7,"食品","京东",114514,1);
//        Cargo cargo8 = new Cargo("洗发水",8,"生活用品","淘宝",114514,1);
//        Cargo cargo9 = new Cargo("洗手液",9,"生活用品","淘宝",114514,960);
//        Cargo cargo10 = new Cargo("餐巾纸",10,"生活用品","淘宝",114514,2);
//        Cargo cargo11 = new Cargo("面包",11,"食品","京东",114514,1);
//        Cargo cargo12 = new Cargo("面包",12,"食品","京东",114514,1);
//        Cargo cargo13 = new Cargo("面包",13,"食品","京东",114514,1);
//        Cargo cargo14 = new Cargo("面包",14,"食品","京东",114514,1);
//        Cargo cargo15 = new Cargo("康师傅",15,"食品","京东",114514,1);
//        Cargo cargo16 = new Cargo("洗发水",16,"生活用品","淘宝",114514,1);
//        Cargo cargo17 = new Cargo("洗手液",17,"生活用品","淘宝",114514,960);
//        Cargo cargo18 = new Cargo("餐巾纸",18,"生活用品","淘宝",114514,2);
//        Cargo cargo19 = new Cargo("面包",19,"食品","京东",114514,1);
//        Cargo cargo20 = new Cargo("面包",20,"食品","京东",114514,1);
//        Cargo cargo21= new Cargo("康师傅",21,"食品","京东",114514,1);
//        Cargo cargo22 = new Cargo("洗发水",22,"生活用品","淘宝",114514,1);
//        Cargo cargo23 = new Cargo("洗手液",23,"生活用品","淘宝",114514,960);

//
//        warehouse.addCargo(cargo1);
//        warehouse.addCargo(cargo2);
//        warehouse.addCargo(cargo3);
//        warehouse.addCargo(cargo4);
//        warehouse.addCargo(cargo5);
//        warehouse.addCargo(cargo6);
//        warehouse.addCargo(cargo7);
//        warehouse.addCargo(cargo8);
//        warehouse.addCargo(cargo9);
//        warehouse.addCargo(cargo10);
//        warehouse.addCargo(cargo11);
//        warehouse.addCargo(cargo12);
//        warehouse.addCargo(cargo13);
//        warehouse.addCargo(cargo14);
//        warehouse.addCargo(cargo15);
//        warehouse.addCargo(cargo16);
//        warehouse.addCargo(cargo17);
//        warehouse.addCargo(cargo18);
//        warehouse.addCargo(cargo19);
//        warehouse.addCargo(cargo20);
//        warehouse.addCargo(cargo21);
//        warehouse.addCargo(cargo22);
//        warehouse.addCargo(cargo23);

        MainFrame mainFrame = new MainFrame("仓库管理系统",warehouse);

    }
}

以上就是全部代码，接下来看看效果

主界面：

添加超出容量的货物后可使用滚动条

 仓库容量设置界面：

进仓出仓界面：

 既然是快递超市仓库管理系统，当然需要出仓码才能出仓啦（doge)

点击预警按钮后三种预警界面（正常，零状态，满状态）：

报废界面：

 点击货物对应按钮后弹出的详细消息弹窗：

信息提示界面:

最后再来谈谈该系统没有完善的地方

        首先，系统的预警系统需要手动点击触发，其实这里可以关联在进仓出仓按钮上，实现自动预警，这里纯粹是博主在设计的时候没有想到。

        另外，在进仓26个货物之后，后面进仓的（第27个以及27以后）货物可能会无法在主界面显示，这个应该是代码问题但博主一直没有解决，如有大佬指正欢迎在讨论区留言。
