【问题标题】:Jasper Reports exports well to PDF but not to ExcelJasper Reports 可以很好地导出到 PDF,但不能导出到 Excel
【发布时间】:2017-01-30 09:44:20
【问题描述】:

我是 Jasper 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为 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,一些字段丢失。我使用的代码是两个类中的一些(每个文件导出都有一个类)

我还看到导出到PDF或Excel的模板是一样的,所以我不知道为什么全部填写PDF而不是Excel。

当我生成 PDF 时,我将所有数据传递给:

JasperExportManager.exportReportToPdfStream(jasperPrint,fileOutputStream);

当我尝试生成 Excel 时,我调用了这个函数:

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 生成良好,Excel 应该这样做,但在阅读 Dave Jarvis 评论后,我正在使用 jrxml 进行更新:

1 - 有 3 个通知:通知 A - 通知 B - 通知 C。 2 - Inform A 有一个页眉和页脚,每一行都由 Inform B 填充。 3 - 在 Inform B 上它没有显示在 Excel 上的字段是 numberIndex

【问题讨论】:

  • 你用过apache poilib吗?
  • 嗨,Ataur,我正在进行一个项目,我无法更改为 Apache Poi:/
  • 它是网络项目还是基于桌面的?
  • 我是 Java 桌面项目。
  • @Aker666:JRXML 中的重叠元素可能会导致非 PDF 格式的布局不正确。请提供有问题的 JRXML 代码的最低工作示例,不提供任何公司特定信息。

【解决方案1】:

我不知道是否是错误,但我复制了正在工作的 jrxml 的其他 textFieldExpression 行,将其重命名为未显示的值,现在它显示的值。

什么鬼……

【讨论】:

    【解决方案2】:

    在您的 jrxml 设计报告列中不应重叠。因为如果您有两个共享某个区域的元素,则将无法正确呈现并导致 Excel 报告中缺少列或数据。
