小程序（十四）后端-签到成功

---

一、持久层

1、CheckinMapper.xml

<select id="searchTodayCheckin" parameterType="int" resultType="HashMap">SELECTu.name,u.photo,d.dept_name AS deptName,ck.address,CASEWHEN ck.status=1 THEN '正常'WHEN ck.status=2 THEN '迟到'END AS status,DATE_FORMAT(ck.create_time,'%H:%i') AS checkinTime,ck.dateFROM tb_user AS uLEFT JOIN tb_dept AS d ON u.dept_id = d.idLEFT JOIN tb_checkin AS ck ON u.id = ck.user_id AND ck.date = CURRENT_DATEWHERE u.id = #{userId} AND u.status=1</select><select id="searchCheckinDays" parameterType="int" resultType="long">SELECT COUNT(*) AS countFROM tb_checkinWHERE user_id=#{userId}</select><select id="searchWeekCheckin" parameterType="HashMap" resultType="HashMap">SELECTCAST(date AS CHAR) AS date,IF(status=1,'正常','迟到') AS statusFROM tb_checkinWHERE user_id=#{userId} AND date BETWEEN #{startDate} AND #{endDate}</select>

2、CheckinMapper.java

@Mapper
public interface TbCheckinDao {public HashMap searchTodayCheckin(int userId);public long searchCheckinDays(int userId);public ArrayList<HashMap> searchWeekCheckin(HashMap param);}

3、TbHolidaysDao.xml

<select id="searchHolidaysInRange" parameterType="HashMap" resultType="String">SELECT dateFROM tb_holidaysWHERE date BETWEEN #{startDate} AND #{endDate}</select>

4、TbHolidaysDao.java

public interface TbHolidaysDao {
……public ArrayList<String> searchHolidaysInRange(HashMap param);}

5、TbWorkdayDao.xml

<select id="searchWorkdayInRange" parameterType="HashMap" resultType="String">SELECT dateFROM tb_workdayWHERE date BETWEEN #{startDate} AND #{endDate}</select>

6、TbWorkdayDao.java

public interface TbWorkdayDao {……
public ArrayList<String> searchWorkdayInRange(HashMap param);
}

二、业务层

1、 CheckinService.java

 public class CheckinServiceImpl{……public HashMap searchTodayCheckin(int userId) {HashMap map = checkinDao.searchTodayCheckin(userId);return map;}public long searchCheckinDays(int userId) {long days = checkinDao.searchCheckinDays(userId);return days;}public ArrayList<HashMap> searchWeekCheckin(HashMap param) {ArrayList<HashMap> checkinList = checkinDao.searchWeekCheckin(param);ArrayList<String> holidaysList = holidaysDao.searchHolidaysInRange(param);ArrayList<String> workdayList = workdayDao.searchWorkdayInRange(param);DateTime startDate = DateUtil.parseDate(param.get("startDate").toString());DateTime endDate = DateUtil.parseDate(param.get("endDate").toString());DateRange range = DateUtil.range(startDate, endDate, DateField.DAY_OF_MONTH);ArrayList list = new ArrayList();range.forEach(one -> {String date = one.toString("yyyy-MM-dd");//查看今天是不是假期或者工作日String type = "工作日";if (one.isWeekend()) {type = "节假日";}if (holidaysList != null && holidaysList.contains(date)) {type = "节假日";} else if (workdayList != null && workdayList.contains(date)) {type = "工作日";}String status = "";//如果date1 < date2，返回数小于0，date1==date2返回0，date1 > date2 大于0if (type.equals("工作日") && DateUtil.compare(one, DateUtil.date()) <= 0) {status = "缺勤";boolean flag=false;for (HashMap<String, String> map : checkinList) {if (map.containsValue(date)) {status = map.get("status");flag=true;break;}DateTime endTime=DateUtil.parse(DateUtil.today()+""+constants.attendanceEndTime);String today=DateUtil.today();if(date.equals(today)&&DateUtil.date().isBefore(endTime)&&flag==false)
{status="";}}}HashMap map = new HashMap();map.put("date", date);map.put("status", status);map.put("type", type);map.put("day", one.dayOfWeekEnum().toChinese("周"));list.add(map);});return list;}}

三、conroller层

1、编写 TbUserDao.xml 文件，查询员工的入职日期。

 <select id="searchUserHiredate" parameterType="int" resultType="String">SELECT hiredate FROM tb_user WHERE id=#{userId} AND status = 1
</select>

2、编写 TbUserDao.java 接口，定义抽象方法。

 public interface TbUserDao {……public String searchUserHiredate(int userId);}

3、在 UserService.java

 public class UserServiceImpl implements UserService {……@Overridepublic String searchUserHiredate(int userId) {String hiredate = userDao.searchUserHiredate(userId);return hiredate;}}

4、实现查询考勤结果的Web方法

 public class CheckinController {……@Autowiredprivate UserService userService;@Autowiredprivate SystemConstants constants;@GetMapping("/searchTodayCheckin")@ApiOperation("查询用户当日签到数据")public Result searchTodayCheckin(@RequestHeader("token") String token) {int userId = jwtUtil.getUserId(token);HashMap map = checkinService.searchTodayCheckin(userId);map.put("attendanceTime", constants.attendanceTime);map.put("closingTime", constants.closingTime);long days = checkinService.searchCheckinDays(userId);map.put("checkinDays", days);//判断日期是否在用户入职之前DateTime hiredate = DateUtil.parse(userService.searchUserHiredate(userId));DateTime startDate = DateUtil.beginOfWeek(DateUtil.date());if (startDate.isBefore(hiredate)) {startDate = hiredate;}DateTime endDate = DateUtil.endOfWeek(DateUtil.date());HashMap param = new HashMap();param.put("startDate", startDate.toString());param.put("endDate", endDate.toString());param.put("userId", userId);ArrayList<HashMap> list = checkinService.searchWeekCheckin(param);map.put("weekCheckin", list);return Result.ok().put("result", map);}}
