JasperReports 5.6：不推荐使用JRXlsExporter.setParameter

问题描述

  JasperPrint jprint = JasperFillManager.fillReport（expRpg，null，new JRBeanCollectionDataSource（数据列表））; 
 JRXlsExporter exporter = new JRXlsExporter（）; 
 exporter.setParameter（JRXlsExporterParameter.JASPER_PRINT，jprint）; 
 exporter.setParameter（JRXlsExporterParameter.OUTPUT_STREAM，outStream）; 
 exporter.setParameter（JRXlsExporterParameter.IS_DETECT_CELL_TYPE，Boolean.TRUE）; 
 exporter.setParameter（JRXlsExporterParameter.IS_REMOVE_EMPTY_SPACE_BETWEEN_ROWS，Boolean.TRUE）; 
 exporter.exportReport（）; 
  

升级到JasperReports 5.6 所有setParameter都被标记为已弃用，我无法找到适应此代码的文档。

如何将报告导出为xls与 JasperReports 5.6 ？

解决方案

JRExporter在5.6中弃用。他们引入了新的界面导出器，并对所有出口商进行了改进，以具有ExporterInput，ReportExportConfiguration，ExporterConfiguration，ExporterOutput。见下面的链接

这意味着，而不是setParameter，您需要使用上述类或其子类
PDF导出示例创建配置。 Excel导出应遵循相同的方法

  JRPdfExporter exporter = new JRPdfExporter（）; 
 
 exporter.setExporterInput（new SimpleExporterInput（jasperPrint））; 
 exporter.setExporterOutput（outputStream）; 
 SimplePdfExporterConfiguration configuration = new SimplePdfExporterConfiguration（）; 
 exporter.setConfiguration（configuration）; 
 
 exporter.exportReport（）; 
  

Excel对应

 code> JRXlsExporter exporter = new JRXlsExporter（）; 
 exporter.setExporterInput（new SimpleExporterInput（jasperPrint））; 
 exporter.setExporterOutput（new SimpleOutputStreamExporterOutput（destFile））; 
 SimpleXlsReportConfiguration configuration = new SimpleXlsReportConfiguration（）; 
 configuration.setOnePagePerSheet（true）; 
 configuration.setDetectCellType（true）; 
 configuration.setCollapseRowSpan（false）; 
 exporter.setConfiguration（configuration）; 
  

SimpleXlsReportConfiguration将具有excel导出相关配置。根据您的要求设置值

I have this code to export a JasperReprot to XLS:

        JasperPrint jprint=JasperFillManager.fillReport(expRpg, null, new JRBeanCollectionDataSource(datalist));
        JRXlsExporter exporter = new JRXlsExporter();
        exporter.setParameter(JRXlsExporterParameter.JASPER_PRINT, jprint); 
        exporter.setParameter(JRXlsExporterParameter.OUTPUT_STREAM, outStream);
        exporter.setParameter(JRXlsExporterParameter.IS_DETECT_CELL_TYPE, Boolean.TRUE); 
        exporter.setParameter(JRXlsExporterParameter.IS_REMOVE_EMPTY_SPACE_BETWEEN_ROWS, Boolean.TRUE);
        exporter.exportReport();

Upgrading to JasperReports 5.6 all setParameter are flagged as "deprecated" and I can not find documentation to adapt this code.

How to export a report to xls with JasperReports 5.6?

解决方案

JRExporter became deprecated in 5.6. They introduced new interface Exporter and retrofitted all exporters to have ExporterInput, ReportExportConfiguration, ExporterConfiguration,ExporterOutput. See below link

http://jasperreports.sourceforge.net/api/net/sf/jasperreports/export/Exporter.html

This means that instead of setParameter, you need to create configuration using above mentioned classes or their child classesPDF export example. Excel export should follow same methodology

JRPdfExporter exporter = new JRPdfExporter();

exporter.setExporterInput(new SimpleExporterInput(jasperPrint));
exporter.setExporterOutput(outputStream);
SimplePdfExporterConfiguration configuration = new SimplePdfExporterConfiguration();
exporter.setConfiguration(configuration);

exporter.exportReport();

Excel counterpart

JRXlsExporter exporter = new JRXlsExporter();
exporter.setExporterInput(new SimpleExporterInput(jasperPrint));
exporter.setExporterOutput(new SimpleOutputStreamExporterOutput(destFile));
SimpleXlsReportConfiguration configuration = new SimpleXlsReportConfiguration();
configuration.setOnePagePerSheet(true);
configuration.setDetectCellType(true);
configuration.setCollapseRowSpan(false);
exporter.setConfiguration(configuration);

SimpleXlsReportConfiguration will have excel export related configuration. Set values as per your requirement
