问题描述
我需要从字符串数组中动态显示crosstabHeaderCell列。
这是一个json
i had need to show crosstabHeaderCell columns dynamically from string array. this is a 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
}
]
}
]
}
我想要从交叉表中的数组列名列表中显示crosstabHeaderCell。来自上面json的
我能够迭代并将产品名称和位置显示为行，将weekSpend显示为具有交叉表数据集的列
I want to show crosstabHeaderCell from list of values of array columnName in cross tab. from the above json I am able to iterate and show product name and location as rows and weekSpend as column with data set of crosstab as
<crosstabDataset isDataPreSorted="true">
<dataset>
<datasetRun subDataset="crossTabDataSet" uuid="e7b27508-8a48-4785-a48e-c646249df9a9">
<dataSourceExpression><![CDATA[((net.sf.jasperreports.engine.data.JsonQLDataSource)$P{REPORT_DATA_SOURCE}).subDataSource("..values(@size > 0)..weekSpend.*")]]></dataSourceExpression>
</datasetRun>
</dataset>
</crosstabDataset>
当我为crosstabHeaderCell指定列表组件时，如下所示我收到错误参数REPORT_DATA_SOURCE。
when i specify list component for crosstabHeaderCell as below i am getting error parameter REPORT_DATA_SOURCE not found.
<jr:list xmlns:jr="http://jasperreports.sourceforge.net/jasperreports/components" xsi:schemaLocation="http://jasperreports.sourceforge.net/jasperreports/components http://jasperreports.sourceforge.net/xsd/components.xsd" printOrder="Horizontal" ignoreWidth="true">
<datasetRun subDataset="listcol" uuid="a13d0691-5b9e-4d9f-aaa0-9d0ff0b67b78">
<dataSourceExpression><![CDATA[((net.sf.jasperreports.engine.data.JsonQLDataSource)$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
the dataset listcol is defined as
<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>
我如何引用交叉表数据集中的值列表。为什么列表失败，REPORT_DATA_SOURCE的参数未找到异常。
我们可以设置交叉表数据集的REPORT_DATA_SOURCE值以供内部数据集使用。
how can a i refer to list of values from crosstab data set. why does list fail with parameter not found exception for REPORT_DATA_SOURCE.can we set the REPORT_DATA_SOURCE value from crosstab dataset to be used by inner dataset.
如果我删除REPORT_DATA_SOURCE jr：list并使用querystring listcol作为$ .columnName。*。我在crosstabHeaderCell中空白
if i remove REPORT_DATA_SOURCE jr:list and use querystring listcol as $.columnName.*. i get blank in crosstabHeaderCell
预期输出为
Expected output is
谢谢

ThanksAnjana,
推荐答案
你需要使用 crosstabParameter s，以便从封闭报告中传递数据，如下所示：
You need to make use of crosstabParameters in order to pass data from the enclosing report, like so:
