java - 贾斯珀报告 5.6 : Could not load the following font

Question

我面临的问题是，JasperReports 仍然找不到 Arial 字体。

我创建了一个具有以下结构的简单 Maven 项目并将其包含到我的主应用程序中。所以主应用程序在类路径中包含已安装的 JAR:

- jasperreports_extension.properties
- fonts
  |-> arial
    |-> ariali.ttf
    |-> arialbi.ttf
    |-> arialbd.ttf
    |-> arial.ttf
  |-> fonts.xml

但我在将报告导出为 PDF 时仍然看到以下异常。

net.sf.jasperreports.engine.JRRuntimeException: Could not load the following font : 
pdfFontName   : Arial
pdfEncoding   : Identity-H
isPdfEmbedded : true

jasperreports_extension.properties

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

fonts.xml:

<?xml version="1.0" encoding="UTF-8"?>
<fontFamilies>
    <fontFamily name="Arial">
        <normal>fonts/arial/arial.ttf</normal>
        <bold>fonts/arial/arialbd.ttf</bold>
        <italic>fonts/arial/ariali.ttf</italic>
        <boldItalic>fonts/arial/arialbi.ttf</boldItalic>
        <pdfEncoding>Identity-H</pdfEncoding>
        <pdfEmbedded>true</pdfEmbedded>
    </fontFamily>
</fontFamilies>

模板

<font fontName="Arial" size="8" pdfFontName="Arial" pdfEncoding="Identity-H" isPdfEmbedded="true"/>

Answer 1

问题出在模板本身:在一个字体标签中 <fontName>属性丢失:

不起作用:

<font size="12" isBold="true" pdfFontName="Arial"/>

有效:

<font fontName="Arial" size="12" isBold="true" pdfFontName="Arial" pdfEncoding="Identity-H" isPdfEmbedded="true"/>
