Jasper报告 - 在PDF文档中设置作者属性 [英] Jasper Report - Set Author property in a PDF document

问题描述

有没有办法通过在从Java调用Jasper时设置参数来将Author属性设置为PDF文档。

Is there a way to set the Author property to a PDF document by setting a parameter when calling Jasper from Java.

这是我从Java生成Jasper报告的方式。

This is how I generate a Jasper report from Java.

      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);  

推荐答案

查看静态字段 METADATA_AUTHOR http://jasperreports.sourceforge.net/api/net/sf/jasperreports/engine/export/JRPdfExporterParameter.html\"rel =nofollow> 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();
