[Java]签到业务的编写

ゝ一纸荒年。 2024-02-23 08:16 109阅读 0赞

#### 业务分析 ####

签到需要加金币（虚拟币），需要展示金币的流水

金币要加在用户字段

金币流水要给钱包表添加信息

签到要判断时间是否会重复签到

#### 开干 ####

这是存储金币的数据库表，detail是签到或者订单给用户加了或减了多少金币

编写钱包的签到接口

@Service
    public class WalletServiceImpl extends ServiceImpl<WalletMapper, Wallet> implements WalletService {
    
        @Autowired
        private WalletMapper mapper;
    
        @Override
        public boolean signIn(Integer userId) {
            QueryWrapper<Wallet> wrapper = new QueryWrapper<Wallet>().eq("user_id",userId).eq("order_id",0).orderByDesc("time").last("limit 1");
            Wallet one = getOne(wrapper);
    
            if (one == null || !TimeUtil.isNow(one.getTime())){
                passSignIn(userId);
                return true;
            }else {
                return false;
            }
        }
    
        private void passSignIn(Integer userId){
            Wallet wallet = new Wallet();
            wallet.setUserId(userId);
            wallet.setOrderId(0);
            wallet.setTime(new Date());
            wallet.setDetail(REWARD);
            save(wallet);
        }
    }

签到业务的实现

public class TimeUtil {
        // 默认的年月日的格式. yyyy-MM-dd
        public static final String PATTEN_DEFAULT_YMD = "yyyy-MM-dd";
    
    
        /**
         * 判断日期是不是今天
         * @param date
         * @return    是返回true，不是返回false
         */
        public static boolean isNow(Date date) {
    
            // 当前时间
            Date now = new Date();
            SimpleDateFormat sf = new SimpleDateFormat(PATTEN_DEFAULT_YMD);
            //获取今天的日期
            String nowDay = sf.format(now);
            //对比的时间
            String day = sf.format(date);
    
            return nowDay.equals(day);
        }
    
    }

时间判断工具类

在UserService封装一下

@Override
        public String userSign(HttpServletRequest request) {
            Integer id = Integer.valueOf(TokenUtil.getUserId(request));
    
            if (walletService.signIn(id)){
                User user = getById(id);
                user.setWallet(user.getWallet() + REWARD);
                updateById(user);
                return "签到成功";
            }else {
                return "签到失败（今日内重复签到）";
            }
        }

接口层

@Controller
    public class UserController {
    
        @Autowired
        private UserService service;
    
        @Autowired
        private WalletService walletService;
    
        @RequestMapping(value = "/user/sign_in",method = RequestMethod.GET)
        @ResponseBody
        public CommonResult<String> userSignIn(HttpServletRequest request){
            String msg;
            return ( msg = service.userSign(request) ).contains("成功") ? CommonResult.success(null,msg) : CommonResult.failed(msg);
        }

查询签到流水

#### 查询金币流水 ####

@Override
        public List<WalletVO> userSignList(HttpServletRequest request) {
            Integer userId = Integer.valueOf(TokenUtil.getUserId(request));
            QueryWrapper<Wallet> wrapper = new QueryWrapper<Wallet>().eq("user_id",userId).orderByDesc("time");
            List<Wallet> list = list(wrapper);
            List<WalletVO> vos = new LinkedList<>();
            for (Wallet wallet : list) {
                WalletVO vo = new WalletVO();
                BeanUtils.copyProperties(wallet,vo);
                vos.add(vo);
            }
            return vos;
        }

接口

@RequestMapping(value = "/user/wallet/list", method = RequestMethod.GET)
        @ResponseBody
        public CommonResult<List<WalletVO>> userSignInList(HttpServletRequest request){
            return CommonResult.success(walletService.userSignList(request));
        }
