第一种：可以利用缓存，commissionMerchantsBean是传入的参数对象

           //将合作对象更改后，应该在下个月份才生效
            //根据merchants_id查询tst_commission_merchants表获取import_partner_employee_id
            CommissionMerchantsBean merchantsBean = commissionDaoC.getCommissionMerchants(commissionMerchantsBean);
            //获取缓存中的生效时间
            String effectTimeImport = RedisUtils.getKey("effectTimeImport:" + commissionMerchants.getCommission_merchants_id());
            String effectTimeRelation = RedisUtils.getKey("effectTimeRelation:" + commissionMerchants.getCommission_merchants_id());
            if(tst.project.utils.StringUtils.isEmpty(effectTimeImport)){
                //如果为空，设置缓存
                RedisUtils.setKey("effectTimeImport:" + commissionMerchants.getCommission_merchants_id(),String.valueOf(TimeUtils.dateToStr(nextMonthStartTimes,"yyyy-MM")));
            }
            //重新获取
            String effectTimeImport2 = RedisUtils.getKey("effectTimeImport:" + commissionMerchants.getCommission_merchants_id());
			//导入的生效日期不等于当月的则将传入的import_partner_employee_id设置为库中原来的数据
            if(effectTimeImport2.compareTo(TimeUtils.dateToStr(new Date(),"yyyy-MM")) != 0){
                //如果不为空，且缓存中的日期是几个月前的设置下月为生效日期
                RedisUtils.setKey("effectTimeImport:" + commissionMerchants.getCommission_merchants_id(),String.valueOf(TimeUtils.dateToStr(nextMonthStartTimes,"yyyy-MM")));
                //设置导入合作对象员工id为原来的数据
                String importPartnerEmployeeId = merchantsBean.getImport_partner_employee_id();
                commissionMerchantsBean.setImport_partner_employee_id(importPartnerEmployeeId);
            }
            if(tst.project.utils.StringUtils.isEmpty(effectTimeRelation)){
                //如果为空，设置缓存
                RedisUtils.setKey("effectTimeRelation:" + commissionMerchants.getCommission_merchants_id(),String.valueOf(TimeUtils.dateToStr(nextMonthStartTimes,"yyyy-MM")));
            }
            //重新获取
            String effectTimeRelation2 = RedisUtils.getKey("effectTimeRelation:" + commissionMerchants.getCommission_merchants_id());
			//关联的生效日期不等于当月的则将传入的relation_partner_employee_id设置为库中原来的数据
			if(effectTimeRelation2.compareTo(TimeUtils.dateToStr(new Date(),"yyyy-MM")) != 0){
				//如果不为空，且缓存中的日期是几个月前的设置下月为生效日期
                RedisUtils.setKey("effectTimeRelation:" + commissionMerchants.getCommission_merchants_id(),String.valueOf(TimeUtils.dateToStr(nextMonthStartTimes,"yyyy-MM")));
                //设置关联合作对象员工id为原来的数据
                String relationPartnerEmployeeId = merchantsBean.getRelation_partner_employee_id();
                commissionMerchantsBean.setRelation_partner_employee_id(relationPartnerEmployeeId);
            }
            //设置生效时间为下个月
            int num=commissionDaoC.updateCommissionMerchants(commissionMerchantsBean);
            if(num<=0){
                throw new AppException("更新失败!");
            }
