我正在尝试使用Jasper iReport Designer 5.6.0生成一个报告,该报告包含其单元格内的列表.生成的表可能如下所示：
为此,我使用以下XML文件作为数据源：
<report>
<table>
<persons>
<person>
<id>111</id>
<name>John</name>
<addresses>
<address>Johan's Street 1</address>
<address>Johan's Street 2</address>
<address>Johan's Street 3</address>
</addresses>
</person>
<person>
<id>222</id>
<name>Marko</name>
<addresses>
<address>Marko's Street 1</address>
<address>Marko's Street 2</address>
</addresses>
</person>
<person>
<id>333</id>
<name>Tito</name>
<addresses>
<address>Tito's Street 1</address>
<address>Tito's Street 2</address>
<address>Tito's Street 3</address>
<address>Tito's Street 4</address>
</addresses>
</person>
</persons>
</table>
</report>
和JRXML模板：

这就是我得到的结果报告：
是否可以在表元素中包含一个列表元素？如果是的话,我做错了什么？
你很亲密
你的< subDataset name =“PersonsTable”>是正确的！
你的< subDataset name =“AddressesList”>应该
<subDataset name="AddressesList" uuid="5c62f1af-dfc1-49ca-8615-493009f964f6">
<queryString language="xPath">
<![CDATA[/report/table/persons/person/addresses/address]]>
</queryString>
<field name="address" class="java.lang.String">
<fieldDescription><![CDATA[child::text()]]></fieldDescription>
</field>
</subDataset>
您需要到达节点地址
由于您的人员表已经有效,我们只需修复< jr：list>的dataSourceExpression.
<datasetRun subDataset="AddressesList" uuid="c8e1bd7e-b4d8-4e48-8b06-e8fd59846d69">
<dataSourceExpression><![CDATA[((net.sf.jasperreports.engine.data.JRXmlDataSource)$P{REPORT_DATA_SOURCE}).subDataSource("/person/addresses/address")]]></dataSourceExpression>
</datasetRun>
而已
