示例:捞取符合条件的数据
SELECT * FROM tbDebtTransfer where nDebtState in (0, 4, 5, 8) AND lLastTimeMillis < ({currentTimeMillis}-{lTimeMillisInterval|0} * nStep);
【说明】:
lLastTimeMillis :上次操作数据表的时间戳;
currentTimeMillis:当前时间戳
lTimeMillisInterval:步长的基数(例如,基数 lTimeMillisInterval 为 5*60*1000 = 300,000,2次捞取,数据仍未处理,第3次捞取的时间间隔为:lTimeMillisInterval * nStep = 300,000 * 3)
调节数据捞取的节奏:
if (nState == Success) { DebtTransferServiceUtil.updateDebtTransfer(lId, "nDebtState", DebtEnum.Info_Success.getCode(), "strMsg", DebtEnum.Info_Success.getMsg(), "nStep",0 ); }else{ log.error("代偿失败!req=" + cdoRequest); DebtTransferServiceUtil.updateDebtTransfer(lId, "nDebtState", DebtEnum.Info_Failure.getCode(), "strMsg", DebtEnum.Info_Failure.getMsg(), "nStep",1 ); }
数据结构(部分字段):
CREATE TABLE `tbDebtTransfer` ( `lId` bigint(20) NOT NULL AUTO_INCREMENT COMMENT ‘主键‘, `nDebtState` int(11) NOT NULL DEFAULT ‘0‘ COMMENT ‘代偿状态 0-初始值,1-代偿中,2-代偿成功‘, `dtCreateTime` datetime NOT NULL COMMENT ‘创建时间‘, `dtModifyTime` datetime NOT NULL COMMENT ‘最后修改时间‘, `strMsg` varchar(255) COLLATE utf8_bin NOT NULL DEFAULT ‘‘ COMMENT ‘状态信息‘, `nStep` int(11) NOT NULL DEFAULT ‘0‘ COMMENT ‘步长 每访问一次,加1‘, PRIMARY KEY (`lId`), KEY `nDebtState` (`nDebtState`) ) ENGINE=InnoDB AUTO_INCREMENT=335 DEFAULT CHARSET=utf8 COLLATE=utf8_bin COMMENT=‘代偿表‘;
