问题描述

我正在尝试使用 Jasper iReport Designer 5.6.0 生成一个报告，其中包含其单元格内的列表。生成的表格可能如下所示：





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：

这就是我的意思得到报告：




I'm trying to generate a report, using Jasper iReport Designer 5.6.0, with table that contains lists inside its cells. The generated table could look like this:

To do this, I'm using the following XML file as datasource:

<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>

And JRXML template:

                                        <textFieldExpression><![CDATA[$F{address}]]></textFieldExpression>
                                    </textField>
                                </jr:listContents>
                            </jr:list>
                        </componentElement>
                    </jr:detailCell>
                </jr:column>
            </jr:table>
        </componentElement>
    </band>
</detail>

And this is what I'm getting as resulting report:

Is it possible to have a list element inside the table element? If yes, what I'm doing wrong?

解决方案

You are close

Your <subDataset name="PersonsTable"> is correct!

Your <subDataset name="AddressesList"> should be 

<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>

You need to arrive to node address

Since your person table already works we need only to fix the dataSourceExpression for the <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>

Thats it
