感谢Narcis的投入。

我检查了Jasper Report 6.3.0的源代码，并试图了解超链接注册表是如何被替换的。为这个找到了工作。希望对他人有所帮助。下面是注册超链接扩展的代码段。

AbstractHtmlExporter<HtmlReportConfiguration,HtmlExporterConfiguration> exporter = new HtmlExporter();

SimpleHtmlReportConfiguration htmlReportConfig = new SimpleHtmlReportConfiguration();

htmlReportConfig.setHyperlinkProducerFactory(HyperlinkExtensionsRegistryFactory.hyperlinkProducerFactory());

exporter.setConfiguration(htmlReportConfig);

public JRHyperlinkProducerFactory hyperlinkProducerFactory() {
    JRHyperlinkProducerMapFactory producerFactory = new JRHyperlinkProducerMapFactory();
    producerFactory.addProducer("ReportExecution", new <Class_implements_JRHyperlinkProducer>());
    producerFactory.addProducer("Custom", new <Class_implements_JRHyperlinkProducer>());
    return producerFactory;
}
