千峰商城-springboot项目搭建-71-添加购物车记录接口

一、流程分析

 

 

 

二、接口实现（实现添加购物车记录接口）

1.修改购物车数据表结构

 

 

2.数据表修改完成之后，对此表重新进行逆向工程。

3.数据库实现

单表添加操作可以直接使用tkMapper完成。

 

三、业务层实现

ShoppingCartService ：

public interface ShoppingCartService {
    public ResultVO addShoppingCart(ShoppingCart cart);
    
}

 

 addShoppingCartImpl：

@Service
public class addShoppingCartImpl implements ShoppingCartService {

    @Autowired
    private ShoppingCartMapper shoppingCartMapper;

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

    }
}

 

 

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;

    }
}
