在 Docker 中使用 Spring Boot Java 生成 Apache POI xlsx 文件

问题描述 投票：0回答：2

我有一个使用 iTextPdf 生成 PDF 的应用程序，现在我添加了 Apache POI 来根据相同的数据生成 Excel 文件。前端是带有 jQuery 的 JS，后端是带有 Spring Boot、Apache POI 5.0 的 Java 11 (openJDK)。 问题是在 IDE 中运行时一切正常。文件已生成并下载，没有任何问题。当我运行应用程序 docker 容器时出现问题。如果我尝试生成 Excel 文件，则会收到错误：

java.io.IOException: org.apache.poi.ooxml.POIXMLException: java.lang.reflect.InvocationTargetException
，没有“由”引起。 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 在生成文件时使用一些临时文件夹？从 Docker 运行时无法执行此操作？

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生成器：

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);
        headerStyle.setFillPattern(FillPatternType.SOLID_FOREGROUND);
        headerStyle.setAlignment(HorizontalAlignment.CENTER);

        XSSFFont font = workbook.createFont();
        font.setFontName("Arial");
        font.setFontHeightInPoints((short) 12);
        font.setBold(true);
        headerStyle.setFont(font);

        Row header = sheet.createRow(0);

        Cell headerCell = header.createCell(0);
        headerCell.setCellValue("Klientas");
        headerCell.setCellStyle(headerStyle);

        ... 

        CellStyle singleOrderCellStyle = workbook.createCellStyle();
        singleOrderCellStyle.setWrapText(true);
        singleOrderCellStyle.setAlignment(HorizontalAlignment.LEFT);

        AtomicInteger rowCount = new AtomicInteger(1);

        orderList.forEach(order -> {
            Row row = sheet.createRow(rowCount.get());

            Cell cell = row.createCell(0);
            cell.setCellValue(order.getClient().getLabel());
            cell.setCellStyle(singleOrderCellStyle);

            ...

            rowCount.getAndIncrement();
        });

        CellStyle totalStyle = sheet.getWorkbook().createCellStyle();
        totalStyle.setFillForegroundColor(IndexedColors.LIGHT_ORANGE.index);
        totalStyle.setFillPattern(FillPatternType.SOLID_FOREGROUND);
        totalStyle.setAlignment(HorizontalAlignment.CENTER);

        XSSFFont fontTotal = workbook.createFont();
        fontTotal.setFontName("Arial");
        fontTotal.setFontHeightInPoints((short) 12);
        fontTotal.setBold(true);
        totalStyle.setFont(fontTotal);

        Row totalRow = sheet.createRow(rowCount.get());

        Cell cell = totalRow.createCell(0);
        cell = totalRow.createCell(1);
        cell = totalRow.createCell(2);


        cell = totalRow.createCell(3);
        cell.setCellValue(totalCount[0]);
        cell.setCellStyle(totalStyle);

        cell = totalRow.createCell(4);
        cell = totalRow.createCell(5);

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

        return workbook;
    }

我已经用 

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

添加或更改与 apache poi 相关的 jar 到版本 3.17 后，我收到另一个错误：

java.lang.NoClassDefFoundError: Could not initialize class org.apache.poi.xssf.model.SharedStringsTable
java docker apache-poi

解决方案是将apache poi版本降低到3.17版本，将xmlbeans版本降低到2.6.0

我遇到了和你一样的问题，我使用的Apache POI版本是5.2.3。然后我找到了解决方案，在 Dockerfile 中添加这样的命令

RUN apk update && apk add --no-cache fontconfig ttf-dejavu
