我在 Jaspersoft Studio 5.1.0 上设计了一个 JRXML，能够在 Eclipse 和 Windows 机器上生成 CSV 格式的报告。当我将 java 代码导出到 Unix 服务器时，出现以下错误。

Unix 服务器的 Java 版本:“1.7.0.08”

Java 代码:

JasperPrint jasperPrint;
            JasperReport jasperReport;
            HashMap jasperParams = new HashMap();

            InputStream input = new FileInputStream(jrxmlFile);
            JasperDesign design = JRXmlLoader.load(input);
            jasperReport = JasperCompileManager.compileReport(design);
            jasperReport.isIgnorePagination();
            Document document = JRXmlUtils.parse(JRLoader.getLocationInputStream(writeFileDir));

            jasperParams.put(jasperReport.isIgnorePagination(), Boolean.TRUE);
            jasperParams.put(JRXPathQueryExecuterFactory.PARAMETER_XML_DATA_DOCUMENT, document);
            jasperPrint = JasperFillManager.fillReport(jasperReport, jasperParams);

            JRCsvExporter exporter = new JRCsvExporter();
            exporter.setParameter(JRExporterParameter.JASPER_PRINT, jasperPrint);
            exporter.setParameter(JRExporterParameter.OUTPUT_FILE_NAME, csvReportName);
            exporter.exportReport();

最佳答案

我认为 pdfFontName="Helvetica-Bold" 是导致问题的原因。这里有两件事需要考虑。

  1. 当您导出报告并希望在其中显示 Helvetica-Bold 时，您将为它创建字体扩展，除非您的 JVM 已经使用它作为 Helvetica-Bold。
  2. 您必须在 jrxml 文件中创建自定义样式并在那里使用字体，并在使用字体扩展名的情况下将样式应用于元素。

希望对你有帮助。
