Question

我遇到了一个场景，我需要使用索引从列表中传递jasper报表参数值。

我在jasper报告中执行了以下查询，并定义了以下参数。

    <parameter name="clientServiceIds" class="java.util.Collection"/>
        <parameter name="trafficPeriod" class="java.util.Collection"/>
        <parameter name="transactionType" class="java.util.Collection"/>
        <parameter name="transactionStatus" class="java.util.Collection"/>
        <parameter name="roamingPartners" class="java.util.Collection"/>
        <parameter name="ages" class="java.util.Collection"/>

        SELECT
          CLIENT_CODE,
          PARTNER_ORG,
            PARTNER_CODE,
          SERVICE_TYPE,
          TP_ID,
          TRAFFIC_PERIOD,
          SETTLEMENT_TYPE,
          SDR_NET,
          TRAN_CURR_NET,
          TRAN_CURRENCY_ID,
          DUE_DATE,
          TRANSACTION_TYPE,
          STATUS,
          NOTE_ID,
          AGE
        FROM vw_transaction_search
        WHERE $X{IN, client_service_id, clientServiceIds}
        AND $X{IN, PARTNER_SERVICE_ID, roamingPartners}
        AND $X{IN, traffic_period, trafficPeriod}
        AND $X{IN, transaction_type, transactionType}
        AND $X{IN, status_id, transactionStatus}
        AND AGE BETWEEN $P{param1} AND $P{param2}

这里是一个列表，我传递给报告，其中包含索引0和索引1的两个值。所有参数（paramValueMap）我从外部系统获取，我无法修改，

JasperFillManager.fillReport(jasperReport, paramValueMap, connection);

所以我正在寻找一种方法来传递我的Jasper报告SQL中的参数param1和param2来自我的Collection年龄，比如param1 = ages.get（0）和param2 = ages.get（1），所以SQL将会像是

...AND $X{IN, status_id, transactionStatus}
AGE BETWEEN $P{ages.get(0)} AND $P{ages.get(1)}

有没有办法实现这个目标？

我能够通过添加两个额外参数age1＆amp; amp来解决这个问题。 age2并将值传递给列表中添加的参数是详细信息。

<parameter name="trafficPeriod" class="java.util.Collection"/>
    <parameter name="transactionType" class="java.util.Collection"/>
    <parameter name="transactionStatus" class="java.util.Collection"/>
    <parameter name="roamingPartners" class="java.util.Collection"/>
    <parameter name="age" class="java.util.List" isForPrompting="false"/>
    <parameter name="age1" class="java.lang.Integer" isForPrompting="false">
        <defaultValueExpression><![CDATA[$P{age}.get(0)]]></defaultValueExpression>
    </parameter>
    <parameter name="age2" class="java.lang.Integer" isForPrompting="false">
        <defaultValueExpression><![CDATA[$P{age}.get(1)]]></defaultValueExpression>
    </parameter>
    <queryString>
        <![CDATA[SELECT
  CLIENT_CODE,
  PARTNER_ORG,
    PARTNER_CODE,
  SERVICE_TYPE,
  TP_ID,
  TRAFFIC_PERIOD,

  TRAN_CURRENCY_ID,
  DUE_DATE,
  TRANSACTION_TYPE,
  STATUS,
  NOTE_ID,
  AGE
FROM vw_transaction_search
WHERE $X{IN, client_service_id, clientServiceIds}
AND $X{IN, PARTNER_SERVICE_ID, roamingPartners}
AND $X{IN, traffic_period, trafficPeriod}
AND $X{IN, transaction_type, transactionType}
AND $X{IN, status_id, transactionStatus}
AND AGE BETWEEN $P{age1} AND $P{age2}
ORDER BY client_code,
  partner_code,
  traffic_period,
  age]]>
    </queryString>
