Jdbc的一个简单小项目(点餐系统)

刚开始写一点思路没有然后自己慢慢摸索一点一点写  一点一点改，最后也是皇天不负有心人达到了自己想要的成果。

首先，先把结构文件搭建出来

接着把测试类控制台信息写出来

  接着把两个实体类写出来

public class order implements Serializable {
    /*
    实体类
     */
    private Integer id;
    private String name;
    private String menu;
    private Integer copies;
    private Integer time;
    private String address;
    private double money;
    private Integer status;

    public order(){}

    public order(Integer id, String name, String menu, Integer copies, Integer time, String address, double money, Integer status) {
        this.id = id;
        this.name = name;
        this.menu = menu;
        this.copies = copies;
        this.time = time;
        this.address = address;
        this.money = money;
        this.status = status;
    }

    public order(String name, String menu, Integer copies, Integer time, String addrss, double money) {
        this.name = name;
        this.menu = menu;
        this.copies = copies;
        this.time = time;
        this.address = addrss;
        this.money = money;
    }

    public String getName() {
        return name;
    }

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

    public String getMenu() {
        return menu;
    }

    public void setMenu(String menu) {
        this.menu = menu;
    }

    public Integer getCopies() {
        return copies
