主报表在 Jaspersoft Studio 中不显示带有 Java 个 Beans 的基本子报表
The master report does not show basic subreport with Java Beans at Jaspersoft Studio
我在 Jaspersoft Studio 中使用 JavaBeans 生成基本报告 (master/subreport) 时遇到问题。
我创建了 TestMainReport.jrxml 和 TestSubreport.jrxml.
TestMainReport.jrxml 包含两个静态文本字段，在标题栏中标记为 "A Title"，在摘要栏中标记为 "A Summary"。
TestSubreport.jrxml 包含两个静态文本字段，标题 "Subreport Title" 和摘要带 "Subreport Summary"。
我已经为它们分配了 JavaBeans 数据适配器，它们没有被使用（尽管 JavaBean 字段被映射到主报表中。我只是碰巧没有将它们映射到子报表中，因为它们没有被使用）。
已将子报表元素添加到摘要带中的主报表。
当我尝试生成每一份报告时，这两份报告都能很好地单独生成。但是，子报表静态文本不会出现在主报表中。
我原以为子报表的静态文本会出现在主报表中。
我做错了什么？

怎么了？
您没有为子报表指定数据源。您设置了 connectionExpression (<connectionExpression><![CDATA[$P{REPORT_CONNECTION}]]></connectionExpression>) 而不是这个。该连接可以在基于 jdbc 的数据源（报告）的情况下为您提供帮助，但对您的情况没有帮助。
解决方案 1 - 使用 dataSourceExpression
您应该为子报表指定数据源。您可以这样声明子报表元素：
<subreport>
<reportElement x="0" y="30" width="560" height="150"/>
<dataSourceExpression><![CDATA[new net.sf.jasperreports.engine.data.JRBeanCollectionDataSource(testdatasource.CustomerAddressDataSource.getCustomerAddresses())]]></dataSourceExpression>
<subreportExpression><![CDATA["TestSubreport.jasper"]]></subreportExpression>
</subreport>
在这种情况下，CustomerAddressDataSource class 将用于填充子报表。
解决方案 2 - 使用数据适配器的外部定义
您可以将子报表的数据适配器导出到文件中，并将其保存到与模板相同的文件夹中（如果您不想指定数据适配器文件的路径）。
您可以在上下文菜单的帮助下导出 数据适配器 定义 JSS (Jaspersoft Studio):
在您的情况下 - 它将是 CustomerAddressesDataAdapter.xml，内容如下：
<?xml version="1.0" encoding="UTF-8" ?>
<beanDataAdapter class="net.sf.jasperreports.data.bean.BeanDataAdapterImpl"><name>Customer Addresses Data Adapter</name><factoryClass>testdatasource.CustomerAddressDataSource</factoryClass><methodName>getCustomerAddresses</methodName><useFieldDescription>false</useFieldDescription><classpath>C:\somepath\library_with_beans.jar</classpath></beanDataAdapter>
您应该在 net.sf.jasperreports.data.adapter 属性 的帮助下在子报表中指定此适配器。在这个 属性 的帮助下，您应该使用 数据适配器 定义（描述）指定文件名，它可以是带路径的名称。就我而言，它将是：CustomerAddressesDataAdapter.xml.
子报表模板将为：
<?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="TestSubreport" pageWidth="595" pageHeight="842" columnWidth="555" leftMargin="20" rightMargin="20" topMargin="20" bottomMargin="20">

在主报告中，包含子报告的部分将是：
<subreport>
<reportElement x="0" y="30" width="560" height="150"/>
<subreportExpression><![CDATA["TestSubreport.jasper"]]></subreportExpression>
</subreport>
- 与之前的情况一样，您不需要指定连接。
对于第一个解决方案，JSS 的输出结果将是：
