Java实战花店商城系统的实现流程

一、项目简述

本系统功能包括:

商品的分类展示,用户的注册登录,购物车,订单结算,购物车加减,后台商品管理,分类管理,订单管理等等功能。

二、项目运行

环境配置:

Jdk1.8 + Tomcat8.5 + Mysql + HBuilderX(Webstorm也行)+ Eclispe(IntelliJ IDEA,Eclispe,MyEclispe,Sts都支持)。

项目技术:

Springboot + Maven + mybatis+ Vue 等等组成,B/S模式 + Maven管理等等。

用户管理控制层:

/**

* 用户

**/

@RestController

@RequestMapping("user")

public class UserController {

@Autowired

UserService userService;

@Autowired

UserDao dao;

@RequestMapping("/test")

R test() {

R r = new R();

return r.setCode(4000).setMsg(Constant.IMG_PATH).setData(dao.findAll());

}

@RequestMapping("/queryInfoByAccount")

}

int len = carts.size() % Constant.PAGE_SIZE == 0 ? carts.size() / Constant.PAGE_SIZE

: (carts.size() / Constant.PAGE_SIZE + 1);

map.put("items", items);

map.put("len", len);

return r.setCode(2000).setData(map);

}

@RequestMapping("/buy")

R buy(@RequestParam("account") String account) {

R r = new R();

// 查该用户的购物车

List<Cart> carts = (List<Cart>) queryByAccount(account).getData();

for (Cart cart : carts) {

// 增加订单数据

orderService.add(cart);

// 删除购物车数据

cartService.delete(cart.getId());

}

return r.setCode(2000).setMsg(HttpMsg.BUY_OK);

}

@RequestMapping("/create")

R create(@RequestBody Cart cart) {
