在JasperReports的jrxml档案中,是否可以使用参数?
原标题:Is it possible to use parameter in queryString tag in jrxml file in JasperReports?

我正在撰写一份JasperReports方案,其中我希望把质询外包给财产档案。

我在我的 Java方案中把问话说出来。

jrxml档案中,我有以下声明:

<parameter name="mySqlQuery" class="java.lang.String"/>

<queryString> 
    <![CDATA[$P{mySqlQuery}]]>
</queryString>

Java方案如下:

hashmap.put("mySqlQuery", this.mySqlQuery);

JasperReport jasperReportMyClass = JasperCompileManager.compileReport(this.reportMyClass);
JasperPrint jasperPrintMyClass = JasperFillManager.fillReport(jasperReportMyClass, hashmap, con);
jprintList.add(jasperPrintMyClass);

然后我出口到哪儿。

如果在JRXML<><><>>>>><>queryString tags中直接出现同样的问题,则该调查将处以罚款。

Thanks for reading!

Is it possible to use parameter in queryString tag in jrxml file in jasper report?

Yes, it is possible.

Try to use $P!{mySqlQuery} expression instead of $P{mySqlQuery} in your jrxml file.
