JasperReports 不生成粗体报告

Question

我已阅读 JasperReports - Fonts Sample (version 6.2.0) 官方教程，以使用与设计字体样式相同的方式生成我的报告。

这是我的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.dejavu=net/sf/jasperreports/fonts/fonts.xml
net.sf.jasperreports.extension.simple.font.families.arial=net/sf/jasperreports/fonts/fonts.xml

这是我的fonts.xml：

<?xml version="1.0" encoding="UTF-8"?>
<fontFamilies>
    <fontFamily name="DejaVu Sans">
        <normal>net/sf/jasperreports/fonts/dejavu/DejaVuSans.ttf</normal>

    </fontFamily>
</fontFamilies>

我将字体放在我的 jar 中，但是当我生成报告时，字体样式仍然没有出现。我错过了什么吗？

Answer 1

你的 xml 和 ttf 文件需要有正确的路径，它遵循与 java 包相同的样式。

例子

如果您的 jasperreports_extension.properties 位于项目根文件夹中（我建议您这样做，因为它需要由 jasper-reports 找到）并且您在名为 @987654330 的文件夹中有 fonts.xml 和 ttf 文件@。

jasperreports_extension.properties 中的引用将是：

net.sf.jasperreports.extension.simple.font.families.myFonts=fonts/fonts.xml

在fonts.xml

<fontFamily name="DejaVu Sans">
    <normal>fonts/DejaVuSans.ttf</normal>
    <bold>fonts/DejaVuSans-Bold.ttf</bold>
    .....
</fontFamily>

如果您仍然有问题，我建议您使用像ireport 或jaspersoft-studio 这样的IDE，它们会让您自动为字体扩展（包括您的ttf）生成一个jar。

在生成 pdf 导出文件时，将这个 jar 包含在类路径中就足够了。
