使用 Spring 在 Docker 中引导 Java 生成 Apache POI xlsx 文件
Generating Apache POI xlsx file with Spring Boot Java in Docker
我有使用 iTextPdf 生成 PDF 的应用程序，现在我添加了 Apache POI 以在相同数据上生成 Excel 文件。前端是 jQuery 的 JS，后端是 Java 11 (openJDK) 和 Spring Boot，Apache POI 5.0。
问题是 运行 在 IDE 中一切正常。文件生成并下载没有问题。当我 运行 apps docker 容器时出现问题。如果我尝试生成 Excel 文件，我会收到错误消息：java.io.IOException: org.apache.poi.ooxml.POIXMLException: java.lang.reflect.InvocationTargetExceptionwith no "Caused by"。
我使用 ByteArrayOutputStream 和 OutputStream 生成 xlsx 文件并在浏览器中下载它。我不尝试将文件存储在某个文件夹中，也不使用 Docker 卷。也许 Apache POI 在生成文件时使用了一些临时文件夹？在 Docker?
的 运行 秒内无法执行此操作
提前致谢。
控制器：
try {
Workbook workbook = excelGenerators.getExcelWorkbook(filteredList);
ByteArrayOutputStream boas = new ByteArrayOutputStream();
try {
workbook.write(boas);
} finally {
boas.close();
}
response.setHeader("Expires", "0");
response.setHeader("Cache-Control", "must-revalidate, post-check=0, pre-check=0");
response.setHeader("Pragma", "public");
response.setContentType("application/vnd.ms-excel");
response.setHeader("Content-disposition","attachment; filename=report.xlsx");
response.setContentLength(boas.size());
OutputStream os = response.getOutputStream();
boas.writeTo(os);
os.flush();
os.close();
} catch (Exception e) {
throw new IOException(e.getMessage());
}
Excel发电机：
public Workbook getExcelWorkbook(List<FullOrder> orderList) {
XSSFWorkbook workbook = new XSSFWorkbook();
Sheet sheet = workbook.createSheet("SHEET ONE");
sheet.createFreezePane(0, 1);
sheet.setColumnWidth(0, 16000);

CellStyle headerStyle = sheet.getWorkbook().createCellStyle();
headerStyle.setFillForegroundColor(IndexedColors.AQUA.index);

cell.setCellValue(Double.parseDouble(decimalFormat.format(totalSum[0]).replace(',', '.')));
cell.setCellStyle(totalStyle);
return workbook;

我用 logger.error(e.getClass() + ": " + e.getMessage() + ": " + e.getCause(), e); 更改了 catch，现在堆栈跟踪如下所示：

在将与 apache poi 相关的 jars 添加或更改为版本 3.17 后，我收到另一个错误：
java.lang.NoClassDefFoundError: Could not initialize class org.apache.poi.xssf.model.SharedStringsTable
解决方案是将 apache poi 版本降低到 3.17 版本并将 xmlbeans 版本降低到 2.6.0
