java - JasperReport 异常 : FontExtensionsRegistry. ensureFontExtensions : Loading font extensions from fonts. xml

Question

我刚刚完成了一个项目，但是当我把它放到生产环境中时，JasperReport 在 font.xml 上显示错误。我尝试在我的机器上的终端 (linux) 上运行该项目，但出现了同样的错误，只有当我在 Netebean 上运行时才有效。为什么要在 Netbeans 和终端上工作？

我的项目很简单，我生成 PDF 并通过电子邮件发送。结构是:

jasperreports_extension.properties:

net.sf.jasperreports.extension.registry.factory.fonts=net.sf.jasperreports.engine.fonts.SimpleFontExtensionsRegistryFactory
net.sf.jasperreports.extension.simple.font.families.arial=fonts.xml

字体.xml:

<fontFamily name="Arial">
    <normal>fonts/Arial.ttf</normal>
    <bold>fonts/Arial Bold.ttf</bold>
    <italic>fonts/Arial Italic.ttf</italic>
    <boldItalic>fonts/Arial Bold Italic.ttf</boldItalic>
    <pdfEncoding>Identity-H</pdfEncoding>
    <pdfEmbedded>true</pdfEmbedded>
    <exportFonts>
        <export key="net.sf.jasperreports.html">Arial, Helvetica, sans-serif</export>
        <export key="net.sf.jasperreports.xhtml">Arial, Helvetica, sans-serif</export>
    </exportFonts>
</fontFamily>

Answer 1

在@Petter Friberg 的建议下，我能够确定我的错误的真正来源，他在 Jasper Report 属性文件中。
