Angular+SSM+Ajax的简单购物车实例

使用Angular+SSM+Ajax实现简单的增删改查功能

sql：

drop table if exists shopCar;
create table if not exists shopCar
(
  cid int primary key auto_increment comment '商品编号',
  shopname varchar(128) not null comment '商品名称',
  shopprice decimal(10,2) not null comment '商品单价',
  shopsum int default 1 comment '商品数量'
);
insert into shopCar (shopname, shopprice, shopsum) values ('钢笔',9.9,10);
insert into shopCar (shopname, shopprice, shopsum) values ('橡皮擦',5.6,8);
insert into shopCar (shopname, shopprice, shopsum) values ('铅笔',3.2,4);
insert into shopCar (shopname, shopprice, shopsum) values ('签字笔',2.9,3);
insert into shopCar (shopname, shopprice, shopsum) values ('圆规',12.5,10);
insert into shopCar (shopname, shopprice, shopsum) values ('文具盒',29.7,10);
insert into shopCar (shopname, shopprice, shopsum) values ('彩铅',89.2,5);

select * from shopCar;
