那些遇到过的问题

在jaspersoft子报表中的表中添加更多行时,第一页成功和其他是空的,为什么？

You*_*hky 6 jasper-reports subreport

我有一份主报告,这份主报告包含两个子报告,

第一个子报表包含两个表,当第一个表上有大量数据时,它成功打印第一个页面,但其他页面为空.

预期的输出是继续显示第一个表的行,直到它转到第二个表,如果没有很多数据它正常工作

这个设计代码:

我怎么解决这个问题？

编辑

在尝试更改某些页面属性后,填充报告在搜索到我使用的虚拟器但未解决之后给出了内存不足的异常.

SourceFileName = SourceFileName.replaceAll("//", "/");
                    JRVirtualizer virtualizer = new JRSwapFileVirtualizer(1000, new JRSwapFile(reportsDirString.replaceAll("//", "/"), 2048, 1024), true);

                    JRVirtualizationHelper.setThreadVirtualizer(virtualizer);
                    // .replaceAll("\\\\", "\\\\")
                    parameters.put(JRParameter.REPORT_VIRTUALIZER, virtualizer);

小智 2

子报表很少应放置在“详细信息”区域中，尽管偶尔有正当理由这样做。

这样做的原因是，对于主查询返回的每一行数据，子报告都会复制一次，例如，如果返回 1 行，您将获得每个子报告的 1 个副本，如果返回 100 行，您将获得 100 行每个子报告。如果您的子报告每个也有 100 行，那么您将为每个子报告返回 10k 行，并且很可能会遇到内存不足异常错误。

尝试将子报告移至页眉/页脚区域或摘要区域，然后运行报告。
