使用XML數據源的表元素中的Jasper列表元素

我試圖使用Jasper iReport Designer 5.6.0生成報表，其中的表格包含其單元格內的列表。生成的表看起來是這樣的：使用XML數據源的表元素中的Jasper列表元素

要做到這一點，我使用下面的XML文件作爲數據源：

<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>

而且JRXML模板：

這就是我得到的結果報告：

是否有可能有表元素中的列表元素？如果是，我做錯了什麼？

你靠近

你<subDataset name="PersonsTable">是正確！

你<subDataset name="AddressesList">應該

<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>

您需要到達節點address

既然你的人表已經工作，我們只需要修復的dataSourceExpression爲<jr:list>

<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>

那就是它

我無法對此表示謝意:)我在這個問題上困擾了幾天。我無法找到任何示例或教程來解釋如何在表格中使用列表。比你快速和準確的答案。 – mrm

我的榮幸，謝謝你接受答案 –
