千峰商城-springboot项目搭建-74-购物车列表业务层和控制层实现

 一、业务层实现:
ShoppingCartService :
public interface ShoppingCartService {
    public ResultVO addShoppingCart(ShoppingCart cart);
    
    public ResultVO listShoppingCartsByUserId(int userId);

}

 

ShoppingCartServiceImpl :
复制代码
@Service
public class ShoppingCartServiceImpl implements ShoppingCartService {

    @Autowired
    private ShoppingCartMapper shoppingCartMapper;
    private SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd hh:mm:ss");

    @Override
    public ResultVO addShoppingCart(ShoppingCart cart) {
        cart.setCartTime(sdf.format(new Date()));
        int i = shoppingCartMapper.insert(cart);
        if(i>0){
            return new ResultVO(ResStatus.OK,"success",null);
        }else {
            return new ResultVO(ResStatus.NO,"fail",null);
        }

    }

    @Transactional(propagation = Propagation.SUPPORTS)
    public ResultVO listShoppingCartsByUserId(int userId) {
        List<ShoppingCartVO> list = shoppingCartMapper.selectShopcartByUserId(userId);
        ResultVO resultVO = new ResultVO(ResStatus.OK, "success", list);
        return resultVO;
    }
}
复制代码

 

 

二、控制层实现

ShopcartController :
复制代码
@RestController
@RequestMapping("/shopcart")
@CrossOrigin
@Api(value = "提供购物车业务相关接口",tags = "购物车管理")
public class ShopcartController {
    @Autowired
    private ShoppingCartService shoppingCartService;

    @PostMapping("/add")
    public ResultVO addShoppingCart(@RequestBody ShoppingCart cart,@RequestHeader("token")String token){
        ResultVO resultVO = shoppingCartService.addShoppingCart(cart);
        return resultVO;

    }

    @GetMapping("/list")
    @ApiImplicitParam(dataType = "int",name = "userId",value = "用户id",required = true)
    public ResultVO list(Integer userId,@RequestHeader("token")String token){

            ResultVO resultVO = shoppingCartService.listShoppingCartsByUserId(userId);
            return resultVO;


    }
}
复制代码
