java JasperReports在以pdf格式导出时不维护字体

1 年，6 月 Questions & Answers 2024

我的Java应用程序生成一个填充JasperReports报告的pdf文件，但当我打开pdf文件时，它的字体总是“Arial”，在报告中设置为“DejaVu Sans”

当我使用JasperReports函数导出到pdf文件时，一切都很好（之后我导入了DejaVu Sans的.ttf文件）。只有当我使用Java应用程序时，这个问题才会持续

下面是我的一个子报告的开头

<?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="sub_21" pageWidth="515" pageHeight="842" columnWidth="515" leftMargin="0" rightMargin="0" topMargin="30" bottomMargin="0" uuid="34ff3034-41c3-4268-b500-7252cbe01a14">
    <property name="com.jaspersoft.studio.data.defaultdataadapter" value="One Empty Record"/>
    <parameter name="acp" class="acp.pdfengine.entities.PdfData"/>
    <detail>
        <band height="376" splitType="Stretch">
            <textField isBlankWhenNull="true">
                <reportElement positionType="Float" x="0" y="0" width="181" height="21" isRemoveLineWhenBlank="true" uuid="7b1fe94a-28dd-42d1-b6db-ee2dcc2d7020"/>
                <textElement>
                    <font fontName="DejaVu Sans" size="12" isBold="true"/>
                </textElement>
                <textFieldExpression><![CDATA[$P{acp}.getPdfWords().getRESULT_title()]]></textFieldExpression>
            </textField>

下面是一段java代码，用于填充报告并创建pdf：

filledReport = JasperFillManager.fillReport(report, params, dataSource);
JasperExportManager.exportReportToPdfFile(filledReport, data.getPdfInfo().getResourcesPath() + data.getPdfInfo().getFileName());

这是我的jasperreports字体。xml文件：

<?xml version="1.0" encoding="UTF-8"?>
<fontFamilies>
    <fontFamily name="DejaVu Sans" visible="true">
      <normal>net/sf/jasperreports/fonts/dejavu/DejaVuSans.ttf</normal> 
      <bold>net/sf/jasperreports/fonts/dejavu/DejaVuSans-Bold.ttf</bold> 
      <italic>net/sf/jasperreports/fonts/dejavu/DejaVuSans-Oblique.ttf</italic> 
      <boldItalic>net/sf/jasperreports/fonts/dejavu/DejaVuSans-BoldOblique.ttf</boldItalic> 
      <pdfEncoding>Identity-H</pdfEncoding> 
      <pdfEmbedded>true</pdfEmbedded> 
      <exportFonts>
      <export key="net.sf.jasperreports.html">'DejaVu Sans', Arial, Helvetica, sans-serif</export> 
      <export key="net.sf.jasperreports.xhtml">'DejaVu Sans', Arial, Helvetica, sans-serif</export> 
      </exportFonts>
    </fontFamily>

    <fontFamily name="Pictonic" visible="false">
        <normal>
            <ttf>net/sf/jasperreports/fonts/pictonic/pictonic.ttf</ttf>
            <svg>net/sf/jasperreports/fonts/pictonic/pictonic.svg</svg>
            <eot>net/sf/jasperreports/fonts/pictonic/pictonic.eot</eot>
            <woff>net/sf/jasperreports/fonts/pictonic/pictonic.woff</woff>
        </normal>
        <pdfEncoding>Identity-H</pdfEncoding>
        <pdfEmbedded>true</pdfEmbedded>
    </fontFamily>
</fontFamilies>

有人有同样的问题吗

Python中文网

有 Java 编程相关的问题?
