从主报表传递参数时不显示JasperReports子报表

问题描述

我有一个主要报告，其中Map对象的参数来自Java代码.在主报告中(包括一个子报告)并尝试传递主报告参数.

I have one main report where parameters from java code by Map object.In main report including one subreport and trying to pass main report parameter.

主报表和子报表可以分别正常工作，但主报表不显示子报表.

The main report and subreport working fine separately but main report does not show subreport.

Invoice.jrxml(主报告):

Invoice.jrxml (main report):

推荐答案

子报表没有数据源，并且不生成任何输出(默认情况下).

The subreport has no data source and doesn't generate any output (by default).

(至少)您可以做两件事.

There are (at least) two things that you can do.

1. 将JREmptyDataSource传递到子报表(就像您对Java代码中的主报表所做的那样):

1. Pass a JREmptyDataSource to the subreport (like you do for the master report in your Java code):

<subreport isUsingCache="false">
    <reportElement x="0" y="0" width="200" height="54" uuid="0b04fdb2-f4bb-4db2-935a-be96d92fa8db"/>
    <subreportParameter name="billingAddress">
        <subreportParameterExpression><![CDATA[$P{billingAddress}]]></subreportParameterExpression>
    </subreportParameter>
    <dataSourceExpression><![CDATA[new net.sf.jasperreports.engine.JREmptyDataSource()]]></dataSourceExpression>
    <subreportExpression><![CDATA[$P{filePath} + "/BillingVenueSubReport.jasper"]]></subreportExpression>
</subreport>

在子报表中设置whenNoDataType="AllSectionsNoDetail"(在<jasperReport>级别).

Set whenNoDataType="AllSectionsNoDetail" in the subreport (at the <jasperReport> level). That will result in the subreport printing all bands except the detail band when it has no data (which would do in your case because your subreport only uses the title band).
