本文介绍了如何将报告导出为PDF / A-1a，PDF / A-1b？的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
在jasper-report中生成PDF / A，包含许多陷阱，并且在某些版本的jasper-report中不受支持。这就是为什么我决定通过这个 Q uestion- A nswer帖子，指出将带图表的简单报告导出为PDF / A所需的步骤和库版本

导出为PDF的Java代码（reputation.pdf）
JasperReport report = JasperCompileManager.compileReport（reputation.jrxml）;
JRCsvDataSource datasource = new JRCsvDataSource（usersRep.csv）;
datasource.setFieldDelimiter（';'）;
datasource.setUseFirstRowAsHeader（true）;
JasperPrint jasperPrint = JasperFillManager.fillReport（report，new HashMap< String，Object>（），datasource）;
JRPdfExporter exporter = new JRPdfExporter（）;
exporter.setExporterInput（new SimpleExporterInput（jasperPrint））;
exporter.setExporterOutput（new SimpleOutputStreamExporterOutput（reputation.pdf））;
SimplePdfExporterConfiguration configuration = new SimplePdfExporterConfiguration（）;
configuration.setMetadataAuthor（我只有我）;
exporter.setConfiguration（配置）;
exporter.exportReport（）;
这会将报告导出为pdf，我需要做什么才能生成PDF / A- 1a？
解决方案
JasperReports Library 4.1.2.3或更高版本
对我来说没有一块蛋糕
停止支持
在jasper报告版本6.0.0中，com.itextpdf.text上的 NullPointerException始终抛出.pdf.internal.PdfA1Checker.checkPdfObject 。这已在6.0.4及更高版本中解决，请参阅 Jasper报告跟踪器。
Generating PDF/A in jasper-report, contains numerous pitfalls and is not supported in some versions of jasper-report. This is why I have decided to pass this Question-Answer post, indicating the steps and library version necessary to export a simple report with a graph to PDF/A

Java code to export to PDF (reputation.pdf)
JasperReport report = JasperCompileManager.compileReport("reputation.jrxml");
JRCsvDataSource datasource = new JRCsvDataSource("usersRep.csv");
datasource.setFieldDelimiter(';');
datasource.setUseFirstRowAsHeader(true);
JasperPrint jasperPrint = JasperFillManager.fillReport(report, new HashMap<String, Object>(),datasource);
JRPdfExporter exporter = new JRPdfExporter();
exporter.setExporterInput(new SimpleExporterInput(jasperPrint));
exporter.setExporterOutput(new SimpleOutputStreamExporterOutput("reputation.pdf"));
SimplePdfExporterConfiguration configuration = new SimplePdfExporterConfiguration();
configuration.setMetadataAuthor("Me and only me");
exporter.setConfiguration(configuration);
exporter.exportReport();
This export the report to a pdf, what do I need to do to generate a PDF/A-1a?
解决方案
JasperReports Library 4.1.2.3 or higher is needed (with discontinued support in 6.0.0 see NullPointerException at the end).
These steps are need to generate a PDF/A, they can be achieved both by java code or by setting jrxml property to root tag (jasper-server support). I will show both but only one method is necessary.
Set PDF/A Conformance
java
configuration.setPdfaConformance(PdfaConformanceEnum.PDFA_1A); // or PdfaConformanceEnum.PDFA_1B
jrxml
<property name="net.sf.jasperreports.export.pdfa.conformance" value="pdfa1a" />
Set ICC Profile
to avoid
JRPdfaIccProfileNotFoundException: The ICC profile is not available to the JVM
java
configuration.setIccProfilePath("srgb.icc");
jrxml
<property name="net.sf.jasperreports.export.pdfa.icc.profile.path" value="srgb.icc" />
Embed all font used in reports, using font-extensions
If you still have error
com.lowagie.text.pdf.PdfXConformanceException: All the fonts must be embedded. This one isn't: Helvetica
include a default style in the jrxml indicating fontName that is included in font extension, example
<style name="default" isDefault="true" fontName="DejaVu Sans"/>
Remove transparent objects and layers (Optional Content Groups) they are not allowed
to avoid
PdfXConformanceException: Transparency is not allowed
In example the chart element must be Opaque and to avoid transparency on the labels you can implement a JRChartCustomizer
public class NoTransparencyCustomizer implements JRChartCustomizer{
@Override
public void customize(JFreeChart chart, JRChart jrchart) {
PiePlot plot = (PiePlot) chart.getPlot();
plot.setLabelShadowPaint(Color.GRAY);
}
}
Set Tagged and tag language (unnecessary for PDF/A-1b)
java
configuration.setTagged(true);
configuration.setTagLanguage("en-us");
jrxml
<property name="net.sf.jasperreports.export.pdf.tagged" value="true" />
<property name="net.sf.jasperreports.export.pdf.tag.language" value="en-us"/>
Result
This is the result implementing the above, switching fontName to DejaVu Sans and using the bundled jasperreports-fonts.jar as font-extension. It has been validated successfully on pdf-tools for both PDF/A-1a and PDF/A-1b
No piece of the cake for me
Discontinued support
In jasper report version 6.0.0 a NullPointerException at com.itextpdf.text.pdf.internal.PdfA1Checker.checkPdfObject was always thrown. This has been solved in 6.0.4 and above see Jasper report tracker.
