2.        填充

JasperFillManager

              .fillReport/fillReportToFile/fillReportToStream

n         输入 : inputStream/jasperReport/jasperFileName

n         输出 ( 可选 ) outputStream(ToStream), jrprintFileName(ToFile)

n         参数: Map parameters

n         数据连接 ( 可选 ) connection/dataSource

n         e.g. JasperFillManager.fillReportToFile("sample_report.jasper", "sample_report.jrprint", null, new JREmptyDataSource());

3.        导出

JasperExportManager

.exportReportToHtmlFile/exportReportToPdf/exportReportToPdfFile/exportReportToPdfStream/exportReportToXml/exportReportToXmlFile/exportReportToXmlStream

n         输入 : jasperPrint/sourceFileName

n         输出 ( 可选 ) outputStream(ToStream), destFileName(ToFile)

n         参数: Map parameters

n         数据连接 ( 可选 ) connection/dataSource

n         e.g. JasperFillManager.fillReportToFile("sample_report.jasper", "sample_report.jrprint", null, new JREmptyDataSource());

net.sf.jasperreports.engine.export.JR CsvExporter

JRPdfExporter

JRHtmlExporter

JRRtfExporter

JRTextExporter

JRXmlExporter

n         设置参数 e.g      

exporter.setParameter(JRExporterParameter.JASPER_PRINT,

jasperPrint);

exporter.setParameter(JRExporterParameter.OUTPUT_FILE_NAME, destFileName);

n         导出 exporter.exportReport();     

4.        显示
