@Autowired

    @Autowired
    EmployeeLoginRecordRepository employeeLoginRecordRepository;

 @Override
    public void addLoginRecord(Long userId) {
        EmployeeLoginRecord record = new EmployeeLoginRecord(userId, new Date());
        this.mongoTemplate.insert(record);
    }

 @Override
    public Boolean isFirstLogin(Long userId) {
        //mysql中记录的是否第一次登陆
        Employee employee = this.employeeRepository.getByUserId(userId);
        Integer isFirstLogin = employee == null ? null : employee.getIsFirstLogin();
        boolean isMysqlFirstLogin  = (isFirstLogin == null || !Constants.NOT_IS_FIRST_LOGIN.equals(isFirstLogin));
        //mongodb 判断是否第一次登陆
        Integer count = this.employeeLoginRecordRepository.countByUserId(userId);
        count = count == null ? 0 : count;
        boolean isMongoFirstLoginCount = count.intValue() < 1 ? true : false;
        //mysql 和 mongodb中一个找个不是第一次登陆就返回true
        if (isMysqlFirstLogin || isMongoFirstLoginCount) {
            return true;
        }
        return false;
    }
