JasperReport生成PDF/A类型文档

当JasperReport导出的文档为PDF/A模式时，该PDF为只读可以防止被修改。

1. 设置导出参数

JRPdfExporter exporter = new JRPdfExporter();
        exporter.setExporterInput(SimpleExporterInput.getInstance(jasperPrints));
        exporter.setExporterOutput(new SimpleOutputStreamExporterOutput(filePath));

        // 设置支持SVG显示
        // SimplePdfReportConfiguration pdfReportConfiguration = new SimplePdfReportConfiguration();
        // pdfReportConfiguration.setForceSvgShapes(true);
        // exporter.setConfiguration(pdfReportConfiguration);

        // 配置 PDF 属性
        SimplePdfExporterConfiguration exportConfig = new SimplePdfExporterConfiguration();
        exportConfig.setPdfVersion(PdfVersionEnum.VERSION_1_7);
        exportConfig.setPdfaConformance(PdfaConformanceEnum.PDFA_1A); //高级配置：PDF/X-1a:2001
        exportConfig.setIccProfilePath("D:/CNFRD2.ICC");
        exportConfig.setMetadataAuthor("作者姓名");
        exportConfig.setMetadataCreator("创建者姓名");
        exportConfig.setMetadataTitle("PDF 标题");
        exportConfig.setMetadataSubject("PDF 主题");
        exportConfig.setMetadataKeywords("关键字1, 关键字2");
        exporter.setConfiguration(exportConfig);

        exporter.exportReport();

其中ICC文件可以在Windows系统找到对应的内容，具体路径在C:\Windows\System32\spool\drivers\color里面。

2. 定义导出字体

创建jasperreports_extension.properties文件在resources目录下：

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

其中fonts.xml文件内容如下所示

<?xml version="1.0" encoding="UTF-8"?>

<fontFamilies>
    <fontFamily name="Microsoft YaHei UI">
        <normal>classpath:jasperreport/fonts/mysh.ttf</normal>
        <bold>classpath:jasperreport/fonts/mysh.ttf</bold>
        <italic>classpath:jasperreport/fonts/mysh.ttf</italic>
        <boldItalic>classpath:jasperreport/fonts/mysh.ttf</boldItalic>
        <pdfEncoding>Identity-H</pdfEncoding>
        <pdfEmbedded>true</pdfEmbedded>
        <exportFonts>
            <export key="net.sf.jasperreports.html">'Microsoft YaHei UI'</export>
        </exportFonts>
    </fontFamily>

    <fontFamily name="思源黑体 CN Regular">
        <normal>classpath:jasperreport/fonts/AlibabaPuHuiTi-2-55-Regular.ttf</normal>
        <bold>classpath:jasperreport/fonts/AlibabaPuHuiTi-2-55-Regular.ttf</bold>
        <italic>classpath:jasperreport/fonts/AlibabaPuHuiTi-2-55-Regular.ttf</italic>
        <boldItalic>classpath:jasperreport/fonts/AlibabaPuHuiTi-2-55-Regular.ttf</boldItalic>
        <pdfEncoding>Identity-H</pdfEncoding>
        <pdfEmbedded>true</pdfEmbedded>
        <exportFonts>
            <export key="net.sf.jasperreports.html">'思源黑体 CN Regular'</export>
        </exportFonts>
    </fontFamily>

    <fontFamily name="思源黑体 CN Bold">
        <normal>classpath:jasperreport/fonts/AlibabaPuHuiTi-2-85-Bold.ttf</normal>
        <bold>classpath:jasperreport/fonts/AlibabaPuHuiTi-2-85-Bold.ttf</bold>
        <italic>classpath:jasperreport/fonts/AlibabaPuHuiTi-2-85-Bold.ttf</italic>
        <boldItalic>classpath:jasperreport/fonts/AlibabaPuHuiTi-2-85-Bold.ttf</boldItalic>
        <pdfEncoding>Identity-H</pdfEncoding>
        <pdfEmbedded>true</pdfEmbedded>
        <exportFonts>
            <export key="net.sf.jasperreports.html">'思源黑体 CN Bold'</export>
        </exportFonts>
    </fontFamily>

    <fontFamily name="思源黑体 CN Medium">
        <normal>classpath:jasperreport/fonts/AlibabaPuHuiTi-2-65-Medium.ttf</normal>
        <bold>classpath:jasperreport/fonts/AlibabaPuHuiTi-2-65-Medium.ttf</bold>
        <italic>classpath:jasperreport/fonts/AlibabaPuHuiTi-2-65-Medium.ttf</italic>
        <boldItalic>classpath:jasperreport/fonts/AlibabaPuHuiTi-2-65-Medium.ttf</boldItalic>
        <pdfEncoding>Identity-H</pdfEncoding>
        <pdfEmbedded>true</pdfEmbedded>
        <exportFonts>
            <export key="net.sf.jasperreports.html">'思源黑体 CN Medium'</export>
        </exportFonts>
    </fontFamily>
</fontFamilies>

3. 定义全局默认字体

创建jasperreports.properties文件在resources目录下：

#全局使用的默认字体
net.sf.jasperreports.default.font.name=Microsoft YaHei UI
net.sf.jasperreports.default.font.size=12
net.sf.jasperreports.default.pdf.font.name=Microsoft YaHei UI
net.sf.jasperreports.default.pdf.font.size=12
net.sf.jasperreports.default.pdf.encoding=Identity-H
net.sf.jasperreports.default.pdf.embedded=true
