Question

我的主报告中有一个子报告。这是详细的乐队。问题是它只运行主报告的第一条记录。我希望它可以运行所有细节带的记录。它没有显示在其他页面上。为了运行它，我传输1个sql查询参数来提供详细信息带。

在第一条记录的页面中，显示如下图所示：

在后续记录的页面中，它不显示或不返回数据（我不能说）。如下图所示：

这是主要报告jrxml：

Answer 1

您的报告存在以下几个问题：

子报表的末尾和细节带的末尾之间留有太多空间。 JasperReports将尝试保留该空白，并且可能导致不必要的带/页溢出，甚至在某些情况下无限循环运行。
当查询没有返回任何内容时，您的子报表可能不会产生任何结果（详细信息带的重复次数与mainDataset中的记录数相同 - 由queryString生成的记录数）。这可能就是你在textField之后什么也看不见的原因。要对此进行测试，请手动检查SQL查询，或者在子报表中设置：

无数据类型：无数据部分

并使用您选择的noData添加staticText个频段（来自Jaspersoft Studio的“大纲”视图）。当子报表的mainDataset为空时，这将仅触发noData波段的渲染。这样，当没有任何东西可以显示时，你可以拥有某种占位符。

Jasper报告：仅在第一条记录
