Java Jasper报告可以很好地导出到PDF，但不能导出到Excel

java jasper-reports

Java Jasper报告可以很好地导出到PDF，但不能导出到Excel,java,jasper-reports,export-to-excel,export-to-pdf,Java,Jasper Reports,Export To Excel,Export To Pdf,我是贾斯珀报告的新手。我使用的是5.6.0版本，我可以将一些数据导出到PDF，并且所有字段都填写正确，但是当我尝试将相同的数据导出到Excel时，某些字段丢失。我使用的代码在两个类上都是some（每个文件导出都有一个类）我还读到要导出到PDF或Excel的模板是一样的，所以我不知道为什么全部用PDF而不是Excel填写生成PDF时，我将所有数据传递给： JasperExportManager.exportReportToPdfStream(jasperPrint,fileOutputStre

我是贾斯珀报告的新手。我使用的是5.6.0版本，我可以将一些数据导出到PDF，并且所有字段都填写正确，但是当我尝试将相同的数据导出到Excel时，某些字段丢失。我使用的代码在两个类上都是some（每个文件导出都有一个类）

我还读到要导出到PDF或Excel的模板是一样的，所以我不知道为什么全部用PDF而不是Excel填写

生成PDF时，我将所有数据传递给：

JasperExportManager.exportReportToPdfStream(jasperPrint,fileOutputStream);

当我尝试生成Excel时，我将此函数称为：

private void generateExcel(JasperPrint jasperPrint) throws IOException, JRException {
    JRXlsExporter exporterXLS = new JRXlsExporter();
    JFileChooser jFileChooser = new JFileChooser(".");
    jFileChooser.setFileSelectionMode(JFileChooser.DIRECTORIES_ONLY);
    int status = jFileChooser.showOpenDialog(SIXACOPWorkbench.getWorkbenchContext().getWorkbench().getFrame());
    if (status == JFileChooser.APPROVE_OPTION) {
        if (jFileChooser.getSelectedFile() != null) {
            String pathPDFs = (jFileChooser.getSelectedFile().getAbsolutePath());
            File ficheroXLS = new File(pathPDFs+"//testing.xls");
            FileOutputStream fos = new FileOutputStream(ficheroXLS);
            exporterXLS.setExporterInput(new SimpleExporterInput(jasperPrint));
            exporterXLS.setExporterOutput(new SimpleOutputStreamExporterOutput(fos));
            SimpleXlsReportConfiguration configuration = new SimpleXlsReportConfiguration();
            configuration.setRemoveEmptySpaceBetweenRows(true);
            configuration.setDetectCellType(true);
            configuration.setWhitePageBackground(false);
            exporterXLS.setConfiguration(configuration);
            exporterXLS.exportReport();     
            fos.close();
        }
    }
}

？导出到Excel时我做错了什么

问候

---更新---

我认为如果PDF生成得很好，Excel应该会这样做，但在阅读Dave Jarvis的评论后，我正在用jrxml更新：

1-有3个通知：通知A-通知B-通知C。 2-通知A有一个页眉和页脚，每行由通知B填充。 3-在上，通知B字段，其编号索引显示在Excel上：

4-在通知B上有一个由通知C填写的部分，在通知C上，不显示其扩展名的字段：

我不知道这是否是一个bug，但我复制了jrxml的其他textFieldExpression行，将其重命名为未显示的值，现在是显示的值

见鬼…

我不知道是不是一个bug，但我复制了jrxml的其他textFieldExpression的行，将其重命名为未显示的值，现在是显示的值

该死的…

在我们的jrxml设计报告列中不应该重叠。因为如果您有两个共享某个区域的元素，这将无法正确呈现，并导致excel报告中缺少列或数据。

ur jrxml设计报告中的列不应重叠。因为如果您有两个共享某个区域的元素，这将无法正确呈现，并导致excel报表中缺少列或数据。

您是否使用了

apache poi

lib？Hi Ataur，我在一个项目中，无法更改为Apache Poi:/它是基于web项目还是基于桌面的？我是基于Java的桌面项目。@Aker666:JRXML中的重叠元素可能会导致非PDF文件的布局不正确。@
