商城項目服務端實踐SSM（十）-------前臺_收貨地址接口

一、增加地址

• controller

 @RequestMapping("add.do")
    @ResponseBody
    public ServerResponse add(HttpSession session, Shipping shipping){
        User user= (User) session.getAttribute(Const.CURRENT_USER);
        if (user == null){
            return ServerResponse.createByErrorCodeMessage(ResponseCode.NEED_LOGIN.getCode(),ResponseCode.NEED_LOGIN.getDesc());
        }
            return iShippingService.add(shipping,user.getId());
    }

• impl

//新增地址
    public ServerResponse add(Shipping shipping,Integer userId){
       shipping.setUserId(userId);
       int rowCount=shippingMapper.insert(shipping);
       if (rowCount > 0){
           Map result= Maps.newHashMap();
           result.put("shippingId",shipping.getId());
           return ServerResponse.createBySuccess("新建地址成功",result);
       }
       return ServerResponse.createByErrorMessage("新建地址失敗");
    }

二、修改地址

• controller

    //修改地址
    @RequestMapping("update.do")
    @ResponseBody
    public ServerResponse update(HttpSession session,Shipping shipping){
        User user= (User) session.getAttribute(Const.CURRENT_USER);
        if (user == null){
            return ServerResponse.createByErrorCodeMessage(ResponseCode.NEED_LOGIN.getCode(),ResponseCode.NEED_LOGIN.getDesc());
        }
        return iShippingService.update(user.getId(),shipping);
    }

• impl

//修改地址
    public ServerResponse update(Integer userId,Shipping shipping){
        shipping.setUserId(userId);
        int rowCount=shippingMapper.updateByShipping(shipping);
        if (rowCount>0){
            return ServerResponse.createBySuccess("修改地址成功");
        }
        return ServerResponse.createByErrorMessage("修改地址失敗");
    }

三、刪除地址

• controller

//刪除地址
    @RequestMapping("delete.do")
    @ResponseBody
    public ServerResponse delete(HttpSession session,Integer shippingId){
        User user= (User) session.getAttribute(Const.CURRENT_USER);
        if (user == null){
            return ServerResponse.createByErrorCodeMessage(ResponseCode.NEED_LOGIN.getCode(),ResponseCode.NEED_LOGIN.getDesc());
        }
        return iShippingService.delete(user.getId(),shippingId);
    }

• impl

//刪除地址
    public ServerResponse delete(Integer userId,Integer shippingId){
        int rowCount=shippingMapper.deleteByUserIdShippingId(userId,shippingId);
        if (rowCount>0){
            return ServerResponse.createBySuccess("刪除地址成功");
        }
        return ServerResponse.createByErrorMessage("刪除地址失敗");
    }

四、選中查看具體的地址詳情

• controller

    //選中查看具體的地址詳情
    @RequestMapping("select.do")
    @ResponseBody
    public ServerResponse select(HttpSession session,Integer shippingId){
        User user= (User) session.getAttribute(Const.CURRENT_USER);
        if (user == null){
            return ServerResponse.createByErrorCodeMessage(ResponseCode.NEED_LOGIN.getCode(),ResponseCode.NEED_LOGIN.getDesc());
        }
        return iShippingService.select(shippingId);
    }

• impl

    public ServerResponse select(Integer shippingId){
        Shipping shipping=shippingMapper.selectByPrimaryKey(shippingId);
        if (shipping == null){
            return ServerResponse.createByErrorMessage("查看詳情失敗");
        }
        return ServerResponse.createBySuccess(shipping);
    }

五、地址列表

• controller

    //地址列表
    @RequestMapping("list.do")
    @ResponseBody
    public ServerResponse<PageInfo> list(HttpSession session, @RequestParam(value="pageNum",defaultValue = "1") int pageNum, @RequestParam(value = "pageSize",defaultValue = "10")int pageSize){
        User user= (User) session.getAttribute(Const.CURRENT_USER);
        if (user == null){
            return ServerResponse.createByErrorCodeMessage(ResponseCode.NEED_LOGIN.getCode(),ResponseCode.NEED_LOGIN.getDesc());
        }
        return iShippingService.list(user.getId(),pageNum,pageSize);
    }

• impl

    //地址列表
    public ServerResponse<PageInfo> list(Integer userId,int pageNum,int pageSize){
        //設置起始頁和每頁數量大小
        PageHelper.startPage(pageNum,pageSize);
        //查詢
        List<Shipping> shippingList=shippingMapper.selectByUserId(userId);
        //放在pageInfo裏
        PageInfo pageInfo=new PageInfo(shippingList);
        return ServerResponse.createBySuccess(pageInfo);
    }

六、Mybatis--Mapper.java

public interface ShippingMapper {

    int insert(Shipping record);

    Shipping selectByPrimaryKey(Integer id);
    //修改地址
    int updateByShipping(Shipping record);
    //根據用戶Id和地址Id刪除地址
    int deleteByUserIdShippingId(@Param(value = "userId") Integer userId,@Param(value = "shippingId") Integer shippingId);
    //地址列表
    List<Shipping> selectByUserId(@Param(value = "userId") Integer userId);
}

七、Mybatis--Mapper.xml
