无法删除重复的columnHeaders和pageFooter

Question

我需要以三种不同的格式为我的Web应用程序创建一些报告：PDF，Excel和MSWord。我能够正确生成pdf和.doc格式的报告。但是，当我将同一报表转换为Excel时，columheaders和页脚将多次填充在同一个excel表中。

我认为在jrxml文件中添加以下代码行可以解决我的问题，

<property name="net.sf.jasperreports.export.xls.exclude.origin.band.1"  alue="columnHeader"/>
<property name="net.sf.jasperreports.export.xls.exclude.origin.band.2" value="pageFooter"/>

但我仍然使用多个columheaders获得excel格式的报告。如何删除？

我的完整Jrxml文件是

我生成报告的java代码是

public byte[] generateReportXls (HttpServletRequest request, Map<String, Object> parameters, String fileName, 
        JRBeanCollectionDataSource beanColDataSource)throws JRException, NamingException,  IOException {
    byte[] xlsReport = null;
    JasperReport jasperReport = getCompiledFile(fileName, request); 
    if(jasperReport==null){
        return null;
    }
    JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport,parameters, beanColDataSource);
    if (jasperPrint != null) {
        ByteArrayOutputStream baos = new ByteArrayOutputStream();
        JRXlsExporter exporter = new JRXlsExporter();
        exporter.setExporterInput(new SimpleExporterInput(jasperPrint));
        exporter.setExporterOutput(new SimpleOutputStreamExporterOutput(baos));
        SimpleXlsReportConfiguration configuration = new SimpleXlsReportConfiguration();
        configuration.setOnePagePerSheet(false);
        configuration.setDetectCellType(true);
        configuration.setCollapseRowSpan(false);
        configuration.setWhitePageBackground(false);
        configuration.setIgnoreCellBackground(true);
        configuration.setRemoveEmptySpaceBetweenColumns(true);
        configuration.setRemoveEmptySpaceBetweenRows(true);

        exporter.setConfiguration(configuration); 
        exporter.exportReport();
        xlsReport = baos.toByteArray();         
    }
    return xlsReport;
}
