java - JasperReports 导出到 excel 自动大小列

Question

我对 JRXlsExporter 有疑问。自动调整属性无法正常工作。这是我的 jrxml:

<?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="templ" language="groovy" pageWidth="1100" pageHeight="1400" columnWidth="1060" leftMargin="20" rightMargin="20" topMargin="20" bottomMargin="20" isSummaryNewPage="true" isSummaryWithPageHeaderAndFooter="true" uuid="683fcccd-cd5a-4e1d-a085-b49c54c13fff">
    <property name="ireport.zoom" value="1.2100000000000029"/>
    <property name="ireport.x" value="0"/>
    <property name="ireport.y" value="0"/>
    <property name="net.sf.jasperreports.export.xls.detect.cell.type" value="true"/>
    <property name="net.sf.jasperreports.print.keep.full.text" value="true"/>
    <property name="net.sf.jasperreports.export.xls.wrap.text" value="false"/>
    <property name="net.sf.jasperreports.export.xls.auto.fit.row" value="true"/>
    <property name="net.sf.jasperreports.export.xls.auto.fit.column" value="true"/>
    <queryString language="SQL">
        <![CDATA[]]>
    </queryString>
</jasperReport>

Java 代码:

excelExporter.setParameter(JRXlsExporterParameter.JASPER_PRINT, jasperPrint);
excelExporter.setParameter(JRXlsExporterParameter.OUTPUT_STREAM, outputStream);
excelExporter.setParameter(JRXlsExporterParameter.MAXIMUM_ROWS_PER_SHEET, 65536);
excelExporter.setParameter(JRXlsExporterParameter.IS_IGNORE_CELL_BORDER, Boolean.FALSE);
excelExporter.setParameter(JRXlsExporterParameter.IS_WHITE_PAGE_BACKGROUND, Boolean.FALSE);
excelExporter.setParameter(JRXlsExporterParameter.IS_REMOVE_EMPTY_SPACE_BETWEEN_ROWS, Boolean.TRUE);
excelExporter.setParameter(JRXlsExporterParameter.IS_COLLAPSE_ROW_SPAN, Boolean.TRUE);
excelExporter.setParameter(JRXlsExporterParameter.IS_REMOVE_EMPTY_SPACE_BETWEEN_COLUMNS, Boolean.TRUE);
excelExporter.setParameter(JRXlsExporterParameter.IS_ONE_PAGE_PER_SHEET, Boolean.FALSE);
excelExporter.setParameter(JRXlsExporterParameter.IS_DETECT_CELL_TYPE, Boolean.TRUE);
excelExporter.setParameter(JRXlsExporterParameter.IS_IMAGE_BORDER_FIX_ENABLED, Boolean.TRUE);
excelExporter.setParameter(JRXlsExporterParameter.IS_IGNORE_GRAPHICS, Boolean.FALSE);

并输出结果: resultFile .

例如第一列必须是“客户编号”而不是“客户”

以下属性在报表级别不起作用:

<property name="net.sf.jasperreports.export.xls.auto.fit.row" value="true"/>
<property name="net.sf.jasperreports.export.xls.auto.fit.column" value="true"/>

您必须将它们放在报告元素上(即):

        <staticText>
            <reportElement x="0" y="100" width="100" height="20">
                <property name="net.sf.jasperreports.export.xls.auto.fit.row" value="true"/>
                <property name="net.sf.jasperreports.export.xls.auto.fit.column" value="true"/>
            </reportElement>
            <textElement/>
            <text><![CDATA[Your Static Text]]></text>
        </staticText>

我还建议您尝试使用 net.sf.jasperreports.export.xls.column.width 属性，它更有用。引用:http://jasperreports.sourceforge.net/config.reference.html
