我在primefaces中使用jasper报告3.7.6。我按照班级按升序排列了从1级到5级的学生列表，并且要打印该列表。如果学生，我的jasper print必须从新页面开始来自不同的班级。如何在碧玉报告中解决这个问题？我的碧玉代码是：
<?xml version="1.0" encoding="UTF-8"?>
<jasperReport xmlns="http://jasperreports.sourceforge.net/jasperreports" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://jasperreports.sourceforge.net/jasperreports http://jasperreports.sourceforge.net/xsd/jasperreport.xsd" name="AttendenceSheet" pageWidth="595" pageHeight="842" columnWidth="555" leftMargin="20" rightMargin="20" topMargin="20" bottomMargin="20">

答案 0 :(得分：0)
＆＃34;正常方式＆＃34;要实现这一点，请使用属性isStartNewPage="true"的分组，例如$F{class}
示例（在变量定义下插入）：
<group name="class" isStartNewPage="true">
<groupExpression><![CDATA[$F{class}]]></groupExpression>
<groupHeader>
<band height="10"/>
</groupHeader>
<groupFooter>
<band height="10"/>
</groupFooter>
</group>
分组还可以让你使用两个新乐队（如果你的话），groupHeader（通常你把类名放在这个中）和groupFooter（通常你把总和和计数这个乐队中的专栏）
