Jasper Reports 可以很好地导出为 PDF，但不能导出为 Excel
Jasper Reports exports well to PDF but not to Excel
我是 Jasper Reports 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 并且所有字段都正确填写，但是当我尝试将相同的数据导出到 Excel 时，一些字段丢失了。我使用的代码是这两个类的代码（我有一个 class 用于每个文件导出）
我也看到导出为PDF的模板和Excel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？
此致。
---更新---
我认为如果 PDF 生成良好，Excel 应该可以，但在阅读 Dave Jarvis 评论后我正在更新 jrxml:
1 - 有 3 个通知：通知 A - 通知 B - 通知 C。
2 - Inform A 有页眉和页脚，每一行都由 Inform B 填充。
3 - 在 上通知 B 它在 Excel 上显示的字段是 numberIndex：

我不知道是否是一个错误，但我复制了 jrxml 的其他 textFieldExpression 行，将其重命名为未显示的值，现在显示的值。
什么鬼...
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，那将无法正确呈现并导致 excel 报告中的列或数据丢失。
我是 Jasper Reports 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 并且所有字段都正确填写，但是当我尝试将相同的数据导出到 Excel 时，一些字段丢失了。我使用的代码是这两个类的代码（我有一个 class 用于每个文件导出）
我也看到导出为PDF的模板和Excel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);

我不知道是否是一个错误，但我复制了 jrxml 的其他 textFieldExpression 行，将其重命名为未显示的值，现在显示的值。

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，那将无法正确呈现并导致 excel 报告中的列或数据丢失。
