我是Jasper Reports的新手。我正在使用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，某些字段会丢失。我使用它的代码是两个clases上的一些代码（每个文件导出都有一个类）
我还读到导出到PDF或Excel的模板是相同的，所以我不知道为什么用PDF而不是Excel填充所有。
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，我称这个函数为：
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时我出错了什么？
问候。
---更新---
我认为，如果PDF生成良好，Excel应该这样做，但在读完Dave Jarvis评论后我用jrxml更新：
1 - 有3个通知：通知A - 通知B - 通知C. 2 - 通知A 有页眉和页脚，每行由通知B 填充。 3 - 在通知B Excel 上显示的字段 numberIndex ：

我不知道是不是一个bug，但是我复制了正在运行的jrxml的其他textFieldExpression的行，将其重命名为不显示的值，现在重命名为＆＃39; s显示。
到底是什么......
答案 1 :(得分：0)
不应重叠。因为如果您有两个共享某个区域的元素，则它们将无法正确呈现，并导致excel报告中的列或数据丢失。
