模仿天猫商城的J2EE商城网站项目后端4—util包https://blog.csdn.net/qq_37154145/article/details/122481793模仿天猫商城的J2EE商城网站项目后端6—dao包https://blog.csdn.net/qq_37154145/article/details/122478301User类不省略get、set方法，除此之后的所有实体类均省略。

User.java

package tmall.bean;

public class User {
    private String password;
    private String name;
    private int id;

    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }

    public String getName() {
        return name;
    }

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

Product.java

package tmall.bean;

import java.util.Date;
import java.util.List;

public class Product {
	private int id;
	private String name;
	private String subTitle; // 标题
	private float originalPrice; // 原价
	private float promotePrice; // 促销价
	private int stock; // 库存
	private Date createDate;
	private Category category;
	private ProductImage firstProductImage; // 封面/第一张图片
	private List<ProductImage> productImages; // 产品图片
	private List<ProductImage> productSingleImages; // 展示图片
	private List<ProductImage> productDetailImages; // 详情图片
	private int reviewCount;	
	private int saleCount;
}

Category.java

package tmall.bean;

import java.util.List;

public class Category {
	private int id;
    private String name;
    List<Product> products;
    List<List<Product>> productsByRow; // 按行的product

    @Override
    public String toString() {
        return "Category [name=" + name + "]";
    }
}

productsByRow如下图所示，一个红圈内的商品为一行，每行为一个List<Product>，所有的List<Product>组成的List，就是productsByRow。接下来所有的XXByRow都是这个含义。
