在 Java 批处理中传递 PL/SQL 参数

Question

您好，我有一个邮件批处理应用程序。 在此应用程序中，有一个 sql 脚本，脚本值中的 2 个字段应取自变量，并且此变量连接到服务器中的 .yml 文件。 首先，我从配置文件（.yml）中获取值，但无法在我的 sql 脚本中分配该值。 我也有行映射器。 注意我可以从 .yml 文件中获取值，但我没有成功地将这些值分配给 sql。 这些值在我的 tasklet 中的 createAlertMailDto 方法中，它们的名称是 CountParameterValue 和 IntervalMinuteParameterValue。 我在下面添加我的代码谢谢。 我的 sql：

WITH qM AS (
SELECT /*+parallel(8)*/ mdmtxn.MID,
mdmtxn.MDSTATUS,
mdmtxn.BIN,
COUNT(*) AS COUNT,
ROUND(ratio_to_report(COUNT(*)) OVER (PARTITION BY MID,BIN), 2) AS RATIO,
mer.MERCHANT_NAME
FROM MDM59.MDMTRANSACTION2 mdmtxn
INNER JOIN OC_VPOS.VPOS_MERCHANT mer on mer.MERCHANT_NO = MID AND mer.STATUS = 1
WHERE
mdmtxn.CREATEDDATE > TO_CHAR(SYSDATE - INTERVAL ':intervalMinuteParameterValue'         
MINUTE ,'YYYYMMDD HH24:MI:SS')
GROUP BY mdmtxn.MID, mdmtxn.MDSTATUS, mdmtxn.BIN, mer.MERCHANT_NAME
ORDER BY COUNT(*) DESC, mdmtxn.MID, mdmtxn.BIN
 )
SELECT * FROM qM
WHERE MDSTATUS IN ('2','4','9')
AND COUNT >=: countParameterValue

我的 model

@Value
@Builder
@Data
public class VposNotificationBatchDto {
public String mid;
public String mdStatus;
public String bin;
public String count;
public String ratio;
public String merchantName;
}

我的行映射器：

@Component
public class DailyNotificationReportRw implements 
RowMapper<VposNotificationBatchDto> {
@Override
public VposNotificationBatchDto mapRow(ResultSet rs, int rowNum) throws 
SQLException {
    return VposNotificationBatchDto.builder()
            .mid(rs.getString("MID"))
            .mdStatus(rs.getString("MDSTATUS"))
            .bin(rs.getString("BIN"))
            .count(rs.getString("COUNT"))
            .ratio(rs.getString("RATIO"))
            .merchantName(rs.getString("MERCHANT_NAME"))
            .build();
}

private static class DailyNotificationDetailRwHolder {
    private static final DailyNotificationReportRw INSTANCE = new 
 DailyNotificationReportRw();
}

public static DailyNotificationReportRw getInstance() {
    return DailyNotificationReportRw.DailyNotificationDetailRwHolder.INSTANCE;
}
}
