你好再次:)所以我遇到了在itext7中找到PDfCopy的替代品的问题 . 这行代码遍历要附加的pdf，但在FOR循环中找不到copy.addPage的替换

在从itext5转换为7时，这可以通过哪种方式完成？是应该使用PdfPage而不是PdfCopy还是应该使用另一种方法？

Tnx对此事的任何建议:)

PdfDocument pdfDoc = new PdfDocument(new PdfWriter(inputFilePath));
PdfMerger merger = new PdfMerger(pdfDoc);

Document document = new Document(pdfDoc, PageSize.A4);
FileOutputStream pdfOutputStream = new FileOutputStream(outFile);

PdfReader reader;

PdfCopy copy = new PdfCopy(document, pdfOutputStream);

// list of pages that were appended
List<Integer> appendedPages = new ArrayList<Integer>();
int currentPage = 0;

try {
    reader = new PdfReader(inputFilePath);
    numberOfPages = pdfDoc.getNumberOfPages();

    //load current PDF to new file
    for (int page = 0; page < numberOfPages;) {
        ++currentPage;
        copy.addPage(copy.getImportedPage(reader, ++page));
    }
} catch (InvalidPdfException e) {

}

// iterate files and add            
for (String filePath : filePaths) { 

    reader = new PdfReader(filePath);
    PdfDocument origPdfDoc = new PdfDocument(new PdfReader(filePath));

    // unlock if is encrypted
    unlockPdf(reader);

    //loop over the pages in that document
    numberOfPages = origPdfDoc.getNumberOfPages();
    for (int page = 0; page < numberOfPages;) {
        ++currentPage;
        appendedPages.add(new Integer(currentPage));
        copy.addPage(copy.getImportedPage(reader, ++page));
    }
    merger.merge(origPdfDoc, 1, origPdfDoc.getNumberOfPages());
    origPdfDoc.close();
}
