Question

我正在尝试在数据库中为用户创建表但是我一直在为地址列表提供数据类型应该是用于List地址的SK_USER表中的Address列的数据类型;

请找我的DTO课程 -

package com.shopcart.dto;

import java.util.List;

public class User {

    private String name;
    private String email;
    private String mobile;
    private int age;
    List<Address> adresses;

    public String getName() {
        return name;
    }

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

    public String getEmail() {
        return email;
    }

    public void setEmail(String email) {
        this.email = email;
    }

    public String getMobile() {
        return mobile;
    }

    public void setMobile(String mobile) {
        this.mobile = mobile;
    }

    public int getAge() {
        return age;
    }

    public void setAge(int age) {
        this.age = age;
    }

    public List<Address> getAdresses() {
        return adresses;
    }

    public void setAdresses(List<Address> adresses) {
        this.adresses = adresses;
    }

    @Override
    public String toString() {
        return "User [name=" + name + ", email=" + email + ", mobile=" + mobile + ", age=" + age + ", adresses="
                + adresses + "]";
    }
}

如果您想将多个地址放入单个用户，则需要再创建一个表Address，您可以在其中使用UserId和地址来存储地址。然后为地址表创建AddressDTO。并使用List，它存储AddressDTO的许多对象。

但您需要将id列添加到用户表和dto类中。

代表：

package com.shopcart.dto;

import java.util.List;

public class AddressDTO{

    private int userId;
    private String address;

    public String getAddress() {
        return address;
    }

    public void setAddress(String address) {
        this.address= address;
    }


    public int getUserIde() {
        return userId;
    }

    public void setUserId(int userId) {
        this.userId= userId;
    }

}

为表格列
