Java Apache PDFBox 填充 PDF 字段（错误）

Question

我在尝试填写多个 PDF 中的许多字段时遇到错误。该代码实际上是按预期创建和填充 PDF，并保存 PDF，但代码抛出错误。我正在尝试了解导致这些错误的原因。

Caused by: java.util.zip.DataFormatException: invalid stored block lengths

ERROR FlateFilter FlateFilter: stop reading corrupt stream due to a DataFormatException

ERROR COSParser object stream 51 could not be parsed due to an exception

这是我使用的代码：

        for (int dCounter = 4; dCounter < nColCount; dCounter++) {
            File adobeFile = new File(strDestFileName);

            PDDocument adobeDocument = Loader.loadPDF(adobeFile);
            PDDocumentCatalog adobeCatalog = adobeDocument.getDocumentCatalog();
            PDAcroForm adobeAcroForm = adobeCatalog.getAcroForm();
            PDField adobeField = adobeAcroForm.getField(strArrayHeaders[dCounter]);

            if(!Objects.equals(strArrayCellValues[dCounter], "")) {
                adobeField.setValue(strArrayCellValues[dCounter]);
            }
            FileOutputStream adobeOut = new FileOutputStream(adobeFile);
            adobeDocument.saveIncremental(adobeOut);

            adobeDocument.close();
        }

感谢所有反馈。当我最初写这篇文章并制作基本文件 io no nos 时，我很累。 这就是有效的方法：

File adobeFile = new File(strSourceFileName);
PDDocument adobeDocument = Loader.loadPDF(adobeFile);
PDDocumentCatalog adobeCatalog = adobeDocument.getDocumentCatalog();
PDAcroForm adobeAcroForm = adobeCatalog.getAcroForm();

for (int dCounter = 4; dCounter < nColCount; dCounter++) {

PDField adobeField = adobeAcroForm.getField(strArrayHeaders[dCounter]);

if(!Objects.equals(strArrayCellValues[dCounter], "")) {
    adobeField.setValue(strArrayCellValues[dCounter]);
    }
}

File adobeDestFile = new File(strDestFileName);
FileOutputStream adobeOut = new FileOutputStream(adobeDestFile);
adobeDocument.saveIncremental(adobeOut);
adobeDocument.close();
adobeOut.close();
