JasperReports 5.6：不推荐使用JRXlsExporter.setParameter [英] JasperReports 5.6: JRXlsExporter.setParameter is deprecated

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

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

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 classes PDF 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
