使用JaspersReport加载字体的问题 [英] Issue with loading font using JaspersReport

问题描述

我用iReports导出了这个字体，这个 / b / b / b / b / b / b / b / b / b / b / b / p / p>

  /resources/jasperreports_extension.properties 
 /resources/fonts/fontsfamily1480698239543.xml 
 / resources / fonts / Lato -Bold.ttf 
 /resources/fonts/Lato-BoldItalic.ttf 
 /resources/fonts/Lato-Italic.ttf 
 /resources/fonts/Lato-Regular.ttf 
  

jasperreports_extension.properties ：

  net.sf.jasperreports.extension.registry.factory.fonts = net.sf.jasperreports.engine.fonts.SimpleFontExtensionsRegistryFactory 
 net.sf. jasperreports.extension.registry.factory.simple.font.families = net.sf.jasperreports.engine.fonts.SimpleFontExtensionsRegistryFactory 
 net.sf.jasperreports.extension.simple.font.families.L ato = fonts / fontsfamily1480698239543.xml 
  

和 fontsfamily1480698239543.xml $ b

 <？xml version =1.0encoding =UTF-8？> 
< fontFamilies> 
< fontFamily name =Lato> 
< normal><！[CDATA [fonts / Lato-Regular.ttf]]>< / normal> 
< bold><！[CDATA [fonts / Lato-Bold.ttf]]>< / bold> 
< italic><！[CDATA [fonts / Lato-Italic.ttf]]>< / italic> 
< boldItalic><！[CDATA [fonts / Lato-BoldItalic.ttf]]>< / boldItalic> 
< pdfEncoding><！[CDATA [Cp1250]]>< / pdfEncoding> 
< pdfEmbedded><！[CDATA [true]]>< / pdfEmbedded> 
< / fontFamily> 
< / fontFamilies> 
  

在我的report.jrxml中，我使用以下文本：



 < staticText> 
< reportElement style =Coloredx =119y =93width =161height =15uuid =724f085b-cb64-4d11-ac64-dc23e6f04553/> 
< textElement markup =none> 
 < / textElement> 
< text><！[CDATA [Whatever]]>< / text> 
< / staticText> 
 
< staticText> 
< reportElement x =198y =200width =154height =24uuid =95b310d8-19bf-4485-840f-f3f5076b225e/> 
< textElement markup =none> 
 < / textElement> 
< text><！[CDATA [Address：]]>< / text> 
< / staticText> 
  

当我尝试生成文件时，出现以下错误：



  net.sf.jasperreports.engine.JRRuntimeException：无法加载以下字体：
 pdfFontName：Lato 
 pdfEncoding：Cp1250 
 isPdfEmbedded：true]带有根本原因
 net.sf.jasperreports.engine.JRRuntimeException：无法加载以下字体：
 pdfFontName：Lato 
 pdfEncoding：Cp1250 
 isPdfEmbedded ：true 
 at net.sf.jasperreports.engine.export.JRPdfExporter.getFont（JRPdfExporter.java:2176）〜[jasperreports-6.1.0.jar：6.1.0] 
  

我做错了什么？



更新

我已经根据AlexK和dada67的评论应用了更改，但是这仍然没有改变PDF中生成的字体。但是，我可以在iReports应用程序中看到字体。我现在使用：

 < staticText> 
< reportElement x =198y =200width =154height =24uuid =95b310d8-19bf-4485-840f-f3f5076b225e/> 
< textElement markup =none> 
< font size =14fontName =Lato/> 
< / textElement> 
< text><！[CDATA [Address：]]>< / text> 
< / staticText> 
  

哪个不会引发任何错误。

<下面是我如何在Java中生成pdf：

  ClassLoader classLoader = getClass（）。getClassLoader（）; 
 JasperReport jasperReportSpec = JasperCompileManager.compileReport（classLoader.getResourceAsStream（reporting / Example.jrxml））; 
 JasperPrint jasperPrintSpec = JasperFillManager.fillReport（jasperReportSpec，parameters，new JREmptyDataSource（））; 
 files.put（generatedFile，JasperExportManager.exportReportToPdf（jasperPrintSpec））; 
  

解决方案

原来问题是我没有加载在我的类路径中的字体。感谢@AlexD，我设法使用maven添加它。

I have an issue with loading my own font.

I've exported the font using iReports and this tutorial.

This resulted in having the files:

/resources/jasperreports_extension.properties
/resources/fonts/fontsfamily1480698239543.xml
/resources/fonts/Lato-Bold.ttf
/resources/fonts/Lato-BoldItalic.ttf
/resources/fonts/Lato-Italic.ttf
/resources/fonts/Lato-Regular.ttf

Where jasperreports_extension.properties:

net.sf.jasperreports.extension.registry.factory.fonts=net.sf.jasperreports.engine.fonts.SimpleFontExtensionsRegistryFactory
net.sf.jasperreports.extension.registry.factory.simple.font.families=net.sf.jasperreports.engine.fonts.SimpleFontExtensionsRegistryFactory
net.sf.jasperreports.extension.simple.font.families.Lato=fonts/fontsfamily1480698239543.xml

And fontsfamily1480698239543.xml:

<?xml version="1.0" encoding="UTF-8"?>
<fontFamilies>
   <fontFamily name="Lato">
       <normal><![CDATA[fonts/Lato-Regular.ttf]]></normal>
       <bold><![CDATA[fonts/Lato-Bold.ttf]]></bold>
       <italic><![CDATA[fonts/Lato-Italic.ttf]]></italic>
       <boldItalic><![CDATA[fonts/Lato-BoldItalic.ttf]]></boldItalic>
       <pdfEncoding><![CDATA[Cp1250]]></pdfEncoding>
       <pdfEmbedded><![CDATA[true]]></pdfEmbedded>
   </fontFamily>
</fontFamilies>

In my report.jrxml I use the following for text:

        <staticText>
            <reportElement style="Colored" x="119" y="93" width="161" height="15" uuid="724f085b-cb64-4d11-ac64-dc23e6f04553"/>
            <textElement markup="none">
                <font fontName="Lato" size="10" pdfEncoding="Cp1250" isPdfEmbedded="true"/>
            </textElement>
            <text><![CDATA[Whatever]]></text>
        </staticText>

        <staticText>
            <reportElement x="198" y="200" width="154" height="24" uuid="95b310d8-19bf-4485-840f-f3f5076b225e"/>
            <textElement markup="none">
                <font size="14" isItalic="false" isUnderline="false" pdfFontName="Lato" pdfEncoding="Cp1250" isPdfEmbedded="true"/>
            </textElement>
            <text><![CDATA[Address:]]></text>
        </staticText>

When I am trying to generate the file, I get the following error:

net.sf.jasperreports.engine.JRRuntimeException: Could not load the following font: 
pdfFontName: Lato
pdfEncoding: Cp1250
isPdfEmbedded : true] with root cause
net.sf.jasperreports.engine.JRRuntimeException: Could not load the following font: 
pdfFontName: Lato
pdfEncoding: Cp1250
isPdfEmbedded : true
    at net.sf.jasperreports.engine.export.JRPdfExporter.getFont(JRPdfExporter.java:2176) ~[jasperreports-6.1.0.jar:6.1.0]

What am I doing wrong?

Update

I've applied changes with accordance to comment by AlexK and dada67, but this still didn't changed the font that is generated in the PDF. However, I can see the font in iReports application. I now use:

        <staticText>
            <reportElement x="198" y="200" width="154" height="24" uuid="95b310d8-19bf-4485-840f-f3f5076b225e"/>
            <textElement markup="none">
                <font size="14" fontName="Lato"/>
            </textElement>
            <text><![CDATA[Address:]]></text>
        </staticText>

Which doesn't throw any error.

Here is how I generate the pdf in java:

ClassLoader classLoader = getClass().getClassLoader();
JasperReport jasperReportSpec = JasperCompileManager.compileReport(classLoader.getResourceAsStream("reporting/Example.jrxml"));
JasperPrint jasperPrintSpec = JasperFillManager.fillReport(jasperReportSpec, parameters, new JREmptyDataSource());
files.put("generatedFile", JasperExportManager.exportReportToPdf(jasperPrintSpec));

解决方案

Turns out that the issue was that I was not loading the font in my classpath. Thanks to @AlexD, I've managed to add it using maven.
