这是我的jrxml代码:
<?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="example_report" pageWidth="595" pageHeight="842" columnWidth="555" leftMargin="20" rightMargin="20" topMargin="20" bottomMargin="20"> <property name="ireport.zoom" value="1.0"/> <property name="ireport.x" value="0"/> <property name="ireport.y" value="0"/> <field name="name" class="java.lang.String"/> <field name="test" class="java.lang.String"/> <field name="price" class="java.lang.Double"/> <background> <band splitType="Stretch"/> </background> <title> <band height="79" splitType="Stretch"/> </title> <pageHeader> <band height="35" splitType="Stretch"/> </pageHeader> <columnHeader> <band height="61" splitType="Stretch"/> </columnHeader> <detail> <band height="125" splitType="Stretch"> <textField> <reportElement stretchType="RelativeToBandHeight" x="0" y="0" width="209" height="20"/> <textElement/> <textFieldExpression class="java.lang.String"><![CDATA[$F{name}]]></textFieldExpression> </textField> <textField> <reportElement x="209" y="0" width="201" height="20"/> <textElement/> <textFieldExpression class="java.lang.String"><![CDATA[$F{test}]]></textFieldExpression> </textField> <textField> <reportElement x="410" y="0" width="145" height="20"/> <textElement/> <textFieldExpression class="java.lang.Double"><![CDATA[$F{price}]]></textFieldExpression> </textField> </band> </detail> <columnFooter> <band height="45" splitType="Stretch"/> </columnFooter> <pageFooter> <band height="54" splitType="Stretch"/> </pageFooter> <summary> <band height="42" splitType="Stretch"/> </summary> </jasperReport>
解决方法
我想那是因为你为每一行声明了125px:
<detail> <band height="125" splitType="Stretch">
但只使用20px:
<reportElement stretchType="RelativeToBandHeight" x="0" y="0" width="209" height="20"/>
尝试将细节带设为您使用的高度(20px):
<detail> <band height="20" splitType="Stretch">
我不确定,因为我没有使用Jasper几个月,但试试这个.
