Java 已弃用JRCsvExporter、JRCsvExporterParameter和新替换示例

由于已弃用的

setParameter

方法和已弃用的

JRCsvExporterParameter

类的替换，因此

JRCsvExporter

的适当用途是什么

  JasperReport report = (JasperReport)JRLoader.loadObject(url);

JasperPrint jasperPrint = JasperFillManager.fillReport(report, parameters, 
                          (JRDataSource)this);
ByteArrayOutputStream baos = new ByteArrayOutputStream();
JRCsvExporter exporter = new JRCsvExporter();
exporter.setParameter(JRCsvExporterParameter.JASPER_PRINT, jasperPrint);
exporter.setParameter(JRCsvExporterParameter.OUTPUT_STREAM, baos);
exporter.setParameter(JRCsvExporterParameter.FIELD_DELIMITER, ",");
exporter.exportReport();
