来自子数据集的Jasper Map交叉表crosstab crosstabHeaderCell与crosstabdataset不同
我必须从字符串数组动态显示crosstabHeaderCell列。 这是一个json
{
"header": {
"columnName": [
"Product Store1",
"location"
],
"values": [{
"purchase": {
"name": "bags",
"location": "MainMarket "
},
"weekSpend": [{
"weekStartDate": 20181105,
"spend": 100
},
{
"weekStartDate": 20181112,
"spend": 200
}
]
},
{
"purchase": {
"name": "shoes",
"location": "MainMarket "
},
"weekSpend": [{
"weekStartDate": 20181105,
"spend": 100
},
{
"weekStartDate": 20181112,
"spend": 200
}
]
}
]
}
我想从交叉表中的数组columnName的值列表中显示crosstabHeaderCell。 从上面的json中，我可以迭代并将产品名称和位置显示为行，将weekSpend显示为列，并将交叉表的数据集显示为
<crosstabDataset isDataPreSorted="true">
<dataset>
<datasetRun subDataset="crossTabDataSet" uuid="e7b27508-8a48-4785-a48e-c646249df9a9">
<dataSourceExpression><![CDATA[((net.sf.jasperreports.engine.data.JsonQLDataSource)$P{REPORT_DATA_SOURCE}).subDataSource("..values(@size > 0)..weekSpend.*")]]></dataSourceExpression>
</datasetRun>
</dataset>
</crosstabDataset>
当我如下所示为crosstabHeaderCell指定列表组件时，出现错误参数REPORT_DATA_SOURCE找不到。
<jr:list xmlns:jr="http://jasperreports.sourceforge.net/jasperreports/components" xsi:schemaLocation="http://jasperreports.sourceforge.net/jasperreports/components http://jasperreports.sourceforge.net/xsd/components.xsd" printOrder="Horizontal" ignoreWidth="true">
<datasetRun subDataset="listcol" uuid="a13d0691-5b9e-4d9f-aaa0-9d0ff0b67b78">
<dataSourceExpression><![CDATA[((net.sf.jasperreports.engine.data.JsonQLDataSource)$P{REPORT_DATA_SOURCE}).subDataSource("$.columnName.*")]]></dataSourceExpression>
</datasetRun>
<jr:listContents height="30" width="100">
<textField>
<reportElement x="0" y="0" width="100" height="30" uuid="99c3d5fe-9f90-4efc-bdab-4371eee17d54"/>
<textFieldExpression><![CDATA[$F{namecol}]]></textFieldExpression>
</textField>
</jr:listContents>
</jr:list>
数据集listcol定义为
<subDataset name="listcol" uuid="2630f2ff-b912-4f05-8189-7a5d47eada9e">
<field name="namecol" class="java.lang.String">
<property name="net.sf.jasperreports.jsonql.field.expression" value="[0]"/>
</field>
</subDataset>
我怎么能从交叉表数据集中引用值列表。为什么列表失败，并且REPORT_DATA_SOURCE的参数未找到异常。 我们可以从交叉表数据集中设置REPORT_DATA_SOURCE值以供内部数据集使用。
如果我删除了REPORT_DATA_SOURCE jr：list并使用querystring listcol作为$ .columnName。*。我在crosstabHeaderCell中变得空白
预期输出为

您需要利用crosstabParameter来传递来自所附报告的数据，如下所示：
