08_购物车

一：购物车开发思路

Redis存储购物车数据结构
Hash

K=》menhu:cart
field=>${userid} 
value=>${cart}

二：加购

package com.fengmi.cart;

import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;

@Data
@AllArgsConstructor
@NoArgsConstructor
public class Cart {
    
    private String skuId;
    
    private String title;
    
    private String img;
    
    private String spec;
    
    private Double price;
    
    private  Double marketPrice;
    
    private Integer buyNum;
    
    private boolean choose = false;


}

三：购物车列表
