Jasper报表拆分类型

Question

我正在使用 jasper 报告将我的报告导出到 word 文档。在详细信息部分，我有子报告。我对带拆分类型有疑问。当我选择拆分类型 stretch 或 immediate 时，我遇到了以下问题。

当我选择 Prevent 拆分类型时，我没有收到此错误，但这次在页面底部有很多白色 space if row space 超过保持带的高度。如何在没有边框布局错误的情况下在页面底部部分拆分我的数据？

示例代码。只需复制并粘贴任何 jasper studio 编辑器并在提示时输入长文本（至少填满两页）。

终于解决了。感谢@dada67 的详细解答

解决方案一： 您可以在类路径中创建 jasperreports.properties 文件并将以下行添加到该文件中：

net.sf.jasperreports.consume.space.on.overflow=falsenet.sf.jasperreports.consume.space.on.overflow=false

方案二： 您也可以通过编程方式设置此值

DefaultJasperReportsContext djrc = net.sf.jasperreports.engine.DefaultJasperReportsContext.getI‌nstance();
djrc.setProperty(net.sf.jaspe‌rreports.engine.fill‌.JRFillTextElement.P‌ROPERTY_CONSUME_SPAC‌E_ON_OVERFLOW,
                    Boolean.toString(false));

Answer 1

您描述的问题似乎与http://community.jaspersoft.com/ireport-designer/issues/8146

相同

根据评论，即将发布的版本 (6.3.1) 将修复此问题。

在此期间，您可以在 jasperreports.properties 中设置以下属性来避免此问题：

net.sf.jasperreports.consume.space.on.overflow=false
