可通过Jaspersoft iReprot Designer软件生成字体包：
1.点击 Tools>>Options>>iReport>>Fonts 标签项

2.Install Font

3.选择字体，可选择添加粗体、斜体等配套字体。


4.选择需要打包的字体 >>Export as extension ,输入名字保存成jar文件


生成jar包里面主要有两个配置文件 jasperreports_extension.properties，fontsfamily.xml，也可以不通过iReport自己手动创建字体jar包，按照如下结构：



jasperreports_extension.properties内容如下:

net.sf.jasperreports.extension.registry.factory.fonts=net.sf.jasperreports.engine.fonts.SimpleFontExtensionsRegistryFactory
net.sf.jasperreports.extension.simple.font.families.ireportfamily1381460521792=fonts/fontsfamily1381460521792.xml

fontsfamily.xml内容如下：

<?xml version="1.0" encoding="UTF-8"?>
<fontFamilies>
   <fontFamily name="Arial Unicode MS">
       <normal><![CDATA[fonts/ARIALUNI.TTF]]></normal>
       <pdfEmbedded><![CDATA[false]]></pdfEmbedded>
   </fontFamily>
   <fontFamily name="SimSun">
       <normal><![CDATA[fonts/simsun.ttf]]></normal>
       <pdfEmbedded><![CDATA[false]]></pdfEmbedded>
   </fontFamily>
   <fontFamily name="Times-Roman">
       <normal><![CDATA[fonts/Times-Roman.ttf]]></normal>
       <pdfEmbedded><![CDATA[false]]></pdfEmbedded>
   </fontFamily>
</fontFamilies>
