定期任务,如每月清理(SpringBoot Mybatis-Plus)

@Service
@EnableScheduling //注解开启定时任务功能
public class ChkBillServiceImpl extends ServiceImpl<ChkBillMapper, ChkBill> implements ChkBillService {

    @Scheduled(cron = "0 0 0 1 * ?") //每个月票据号归0
    @Override
    public void eachMonthBillNumToOne() {
        sysDeptMapper.eachMonthBillNumToOne();//执行的任务,票据号归零
    }
}
