java - Jasper Report - 在 PDF 文档中设置作者属性

Question

有没有一种方法可以通过在从 Java 调用 Jasper 时设置参数来将 Author 属性设置为 PDF 文档。

这就是我从 Java 生成 Jasper 报告的方式。

      JasperPrint jasperPrint;
        String outFile = "39285923953222.pdf";
        HashMap hm = new HashMap();
        hm.put("ID",id);
        hm.put("FOOTER",Constants.FOOTER); // Set somehow a string for the author name

        Session session = this.sessionFactory.openSession();
        Connection con = session.connection();

        jasperPrint = JasperFillManager.fillReport(jasperPath + "myReport.jasper", hm, con);
        JasperExportManager.exportReportToPdfFile(jasperPrint, outPath + outFile);  

Answer 1

查看静态字段METADATA_AUTHOR在 JRPdfExporterParameter .
使用JRPdfExporter而不是 JasperExportManager。

示例:

JasperPrint jasperPrint = JasperFillManager.fillReport(jasperPath + "myReport.jasper", hm, con);

JRPdfExporter exporter = new JRPdfExporter();
exporter.setParameter(JRExporterParameter.JASPER_PRINT, jasperPrint);
exporter.setParameter(JRExporterParameter.OUTPUT_FILE, outPath + outFile);
exporter.setParameter(JRPdfExporterParameter.METADATA_AUTHOR, "Adnan");
exporter.setParameter(JRPdfExporterParameter.METADATA_TITLE, "Title");
// ...
exporter.exportReport();
