为什么节不适合页面高度？

Question

<?xml version="1.0" encoding="UTF-8"?>
<jasperReport ... pageWidth="595" pageHeight="842" whenNoDataType="AllSectionsNoDetail" columnWidth="469" leftMargin="70" rightMargin="56" topMargin="130" bottomMargin="56" isSummaryWithPageHeaderAndFooter="true" ...>
    <property ...some properties.../>
    <parameter .../>
    <queryString language="SQL">...</queryString>
    <field .../>
    <variable>...</variable>
    <background>
        <band splitType="Stretch"/>
    </background>
    <title>
        <band height="650" splitType="Stretch">...</band>
    </title>
    <pageFooter>
        <band height="50">...</band>
    </pageFooter>
    <summary>
        <band height="451">...</band>
    </summary>
</jasperReport>

Exception in thread "main" net.sf.jasperreports.engine.design.JRValidationException: Report design not valid : 
 1. The title section, the page and column headers and footers and the margins do not fit the page height.

String myReport = JasperCompileManager.compileReportToFile("myReport.jrxml");

任何关于报告源代码的其他信息，请在评论中让我知道。

它还试图将页脚与标题带(650+50>656)放在同一页上。

如果您喜欢在没有pagefooter单独页面上的标题带，则需要设置属性

isTitleNewPage="true"
