一、业务层实现:
ShoppingCartService :
public interface ShoppingCartService {
public ResultVO addShoppingCart(ShoppingCart cart);
public ResultVO listShoppingCartsByUserId(int userId);
}
ShoppingCartServiceImpl :
@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;
}
}
二、控制层实现
ShopcartController :
@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;
}
}
