Question

我想在我的某个报告中使用条件样式来根据条件更改颜色，但它根本不起作用。

我尝试将其与<parameter></parameter>，<field></field>和<variable></variable>一起使用，但在所有情况下我都会遇到同样的错误：

找不到

（参数或字段或变量）！

这是我的代码JRXML：

我做错了吗？

Answer 1

问题是您使用<jr:table>中使用<subDataset>的样式，因此您无法直接访问到您的主报表参数，需要在此subdataset

中创建参数

<subDataset name="New Dataset 1" uuid="2c012e5d-0895-4ef1-8b47-20fd8c6b281f">
    <parameter name="color" class="java.lang.String"/>
    <queryString>
        <![CDATA[]]>
    </queryString>
    <field name="nom" class="java.lang.String"/>
    <field name="prenom" class="java.lang.String"/>
    <field name="profil" class="java.lang.String"/>
    <field name="tauxCorrect" class="java.lang.Float"/>
    <field name="progres" class="java.lang.Long"/>
</subDataset>

然后在调用jr:table

时传递参数

<jr:table xmlns:jr="http://jasperreports.sourceforge.net/jasperreports/components" xsi:schemaLocation="http://jasperreports.sourceforge.net/jasperreports/components http://jasperreports.sourceforge.net/xsd/components.xsd" whenNoDataType="AllSectionsNoDetail">
    <datasetRun subDataset="New Dataset 1" uuid="7fc961fa-4d60-4d02-8145-f6cbfb54cc10">
        <datasetParameter name="REPORT_DATA_SOURCE">
            <datasetParameterExpression><![CDATA[$P{DS1}]]></datasetParameterExpression>
        </datasetParameter>
        <datasetParameter name="color">
           <datasetParameterExpression><![CDATA[$P{color}]]></datasetParameterExpression>
        </datasetParameter>
    </datasetRun>
    ....
</jr:table>

JasperReports：条件样式错误“参数未找到”？
