我已成功将 jasper 报告添加到我的 java 应用程序中，并通过字体扩展添加了字体。当我在 intelij idea 中运行我的应用程序时，一切正常，报告使用所选字体生成。但是，当我将所有内容编译成一个统一的(单个、胖等)jar 文件，将其部署到 Wildfly 并尝试生成报告时，我收到以下错误:

这是我的字体扩展代码

jasperreports_extension.properties

net.sf.jasperreports.extension.registry.factory.fonts=net.sf.jasperreports.engine.fonts.SimpleFontExtensionsRegistryFactory
net.sf.jasperreports.extension.simple.font.families.ireportfamily1586778266566=fonts/fontsfamily1586778266566.xml

fontsfamily1586778266566.xml:

<?xml version="1.0" encoding="UTF-8"?>
<fontFamilies>
    <fontFamily name="TimesFont">
        <normal><![CDATA[fonts/TimesFont/times.ttf]]></normal>
        <bold><![CDATA[fonts/TimesFont/timesbd.ttf]]></bold>
        <italic><![CDATA[fonts/TimesFont/timesi.ttf]]></italic>
        <boldItalic><![CDATA[fonts/TimesFont/timesbi.ttf]]></boldItalic>
        <pdfEncoding><![CDATA[Cp1251]]></pdfEncoding>
        <pdfEmbedded><![CDATA[true]]></pdfEmbedded>
        <exportFonts/>
    </fontFamily>
    <fontSet name="ReportFontSet">
        <family familyName="TimesFont" primary="true"/>
    </fontSet>
</fontFamilies>

我在 .war 文件 (WEB-INF\lib) 的 lib 文件夹中看到我的字体扩展 jar。

我的环境:

jasperreports:6.12.2
Wildfly 19

附注非常奇怪的是，我从日志中收到以下错误:

Error loading font family: net.sf.jasperreports.engine.fonts.InvalidFontException: Error loading font "net/sf/jasperreports/fonts/icons/icons.ttf"

因为 icon.ttf 位于 jasperreports 中的 jasper 默认字体文件夹中:6.12.2.jar

最佳答案

我找到了这个问题的解决方案。我将 docker 容器与 WildFly 一起使用，在 docker 中我有 Linux，但没有配置字体。我使用了以下命令:

输入:

docker exec -it -u 0 wildfly/bin/bash其中 wildfly 是容器的名称

对于字体(它是解决方案)

sudo apt-get install fontconfig
