为什么子报表在使用 subDataSource() 时只能从 JsonDataSource 获取一行？

Question

我有一个干净的 Jasper 报表，它调用一个没有过滤器的子报表。在该子报表中，我显示了所有 Json 数据（10 行），如果我看到预览，它会起作用：Subreport preview.

问题出在我从主（干净）报表调用子报表时。它只有 professionalName 和子报表的详细信息。它应该显示 professionalName 和所有子报表（每次都是 10 行），但事实并非如此。它只显示当前行，我确定这是因为主报表没有将所有数据源提供给子报表，只提供了该行。这是捕获：Main report preview.

数据源表达式是：

<dataSourceExpression><![CDATA[((net.sf.jasperreports.engine.data.JsonDataSource)$P{REPORT_DATA_SOURCE}).subDataSource()]]></dataSourceExpression>

Json 文件是这个：

如何为我显示的每一行传递整个数据集？谢谢

Answer 1

subDataSource方法在创建新的JsonDataSource实例时使用当前节点。 JasperReports 的未来版本将解决此问题，但在此之前，您需要：

从子报表中删除 Data Source Expression。子报表本身将使用 JSON 数据适配器。
将您的 JSON 数据适配器导出到文件。如果您以前没有在 Jaspersoft Studio 中做过，请参阅 here 中的步骤 #2。
在您的子报表中，将报表的 Default Data Adapter 属性设置为指向您在上一步中保存的适配器。请参阅 here.
如果您注意到自动生成项目，请重新编译您的子报表。

为什么子报表在使用 subDataSource() 时只能从 JsonDataSource 获取一行？

Why does subreport only get one row from a JsonDataSource when using subDataSource()?
