故事：两个领域对象：

class JasperProject {
    private String ...
}

class JasperProjectGroup {
    private String ...
    private List<JasperProject> ...
}

贾斯珀的代码：

        Map<String, Object> parameters = new HashMap<String, Object>();
        List<JasperProjectGroup> groups = buildGroups();
        parameters.put("groups", groups);

        InputStream jasperReportInputStream = ProjectStatusReportGenerator.class.getClassLoader().getResourceAsStream(
                        PROJECT_STATUS_JASPER_REPORT_FILENAME);

        JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReportInputStream, parameters,
                        new JREmptyDataSource());

        ByteArrayOutputStream outputStream = new ByteArrayOutputStream();

        JasperExportManager.exportReportToPdfStream(jasperPrint, outputStream);

        return outputStream.toByteArray();

我想创建一个 pdf 报告，其中每个单独的页面上的每个组表（例如第 1 页上的第 1 组表，第 2 页上第 2 组的表）。但是，当我将组作为参数传递给 Jasper 模板时，它只显示一个表格，其中包含 pdf 报告中的所有组。

jrxml 的 XML 代码

第一个xml：

<?xml version="1.0" encoding="UTF-8"?>
<jasperReport xmlns="http://jasperreports.sourceforge.net/jasperreports" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://jasperreports.sourceforge.net/jasperreports http://jasperreports.sourceforge.net/xsd/jasperreport.xsd" name="timesheets" pageWidth="595" pageHeight="842" columnWidth="555" leftMargin="20" rightMargin="20" topMargin="20" bottomMargin="20">
    <property name="ireport.zoom" value="1.0"/>
    <property name="ireport.x" value="0"/>
    <property name="ireport.y" value="0"/>
    <parameter name="groups" class="java.util.Collection"/>
    <background>
        <band splitType="Stretch"/>
    </background>
    <detail>
        <band height="800" splitType="Stretch">
            <subreport runToBottom="true">
                <reportElement x="0" y="0" width="515" height="800"/>
                <dataSourceExpression><![CDATA[(new net.sf.jasperreports.engine.data.JRBeanCollectionDataSource($P{groups}))]]></dataSourceExpression>
                <subreportExpression><![CDATA[net.sf.jasperreports.engine.data.JRBeanCollectionDataSource.class.getClassLoader().getResourceAsStream("projectgroup.jasper")]]></subreportExpression>
            </subreport>
        </band>
    </detail>
</jasperReport>

第二个模板（projectgroup.jrxml）：

<?xml version="1.0" encoding="UTF-8"?>
<jasperReport xmlns="http://jasperreports.sourceforge.net/jasperreports" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://jasperreports.sourceforge.net/jasperreports http://jasperreports.sourceforge.net/xsd/jasperreport.xsd" name="projectgroup" pageWidth="595" pageHeight="842" columnWidth="555" leftMargin="20" rightMargin="20" topMargin="20" bottomMargin="20">
    <property name="ireport.zoom" value="1.0"/>
    <property name="ireport.x" value="0"/>
    <property name="ireport.y" value="0"/>
    <subDataset name="TableDataset1">
        <field name="projectName" class="java.lang.String"/>
        <field name="bookedHours" class="java.lang.String"/>
        <field name="predictedHours" class="java.lang.String"/>
        <field name="burnedHours" class="java.lang.String"/>
        <field name="percentageComplete" class="java.lang.String"/>
        <field name="bookedHoursBurned" class="java.lang.String"/>
    </subDataset>
    <field name="jasperProjectStatusReports" class="java.util.List"/>
    <detail>
        <band height="50" splitType="Stretch">
            <subreport>
                <reportElement x="0" y="0" width="515" height="50"/>
                <dataSourceExpression><![CDATA[(new net.sf.jasperreports.engine.data.JRBeanCollectionDataSource($F{jasperProjectStatusReports}))]]></dataSourceExpression>
                <subreportExpression><![CDATA[net.sf.jasperreports.engine.data.JRBeanCollectionDataSource.class.getClassLoader().getResourceAsStream("projectgroup_table.jasper")]]></subreportExpression>
            </subreport>
        </band>
    </detail>
</jasperReport>

第三个模板 xml (projectgroup_table.jasper)：

<?xml version="1.0" encoding="UTF-8"?>
<jasperReport xmlns="http://jasperreports.sourceforge.net/jasperreports" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://jasperreports.sourceforge.net/jasperreports http://jasperreports.sourceforge.net/xsd/jasperreport.xsd" name="projectgroup_table" pageWidth="595" pageHeight="842" columnWidth="555" leftMargin="0" rightMargin="0" topMargin="0" bottomMargin="0">

对此有什么想法吗？谢谢。

是的，这是可以做到的。如果您使用 ireprt... 扩展详细信息字段，则当您的一个组被打印时，其他组将没有空间，因此下一组将在下一页上。
