iText7でPDFを生成する際に“Pdf indirect object belongs to other PDF document. Copy object to current pdf document.”の例外が発生する
私はiText7でpdfを生成する際に、下記の事が発生しています。
com.itextpdf.kernel.PdfException: Pdf indirect object belongs to other PDF document. Copy object to current pdf document.

私が生成するコード
public void generatePDF(CreditQueryData creditQueryData, Map<String, UserCreditContentView> contentViewMap, List<PackageCreditContentView> needRetrievedCreditContentList, File pdfFile, BigDecimal score) throws Exception {
if (!pdfFile.exists()) {
boolean x = pdfFile.createNewFile();
if (!x) {
LOG.error("生成文件出错" + pdfFile.getPath());
return;
}
}
PdfDocument pdf = new PdfDocument(new PdfWriter(new FileOutputStream(pdfFile)));
Document document = new Document(pdf, PageSize.A4);
document.setRenderer(new DocumentRenderer(document));
pdf.addEventHandler(PdfDocumentEvent.END_PAGE, new WatermarkingEventHandler());
try {
//operate code just add tableA tableB tableC...
} catch (Exception e) {
LOG.info();
} finally {
document.close(); //exception throws here
}
}
iText7での私のスタイルコードは、
private PdfFont bfChinese = null;
サービスコンストラクタで呼び出されます。
フォントをstatic
で設定しようとしましたが、動作しませんでした。 これはplace throw例外です。
private void write(PdfIndirectReference indirectReference) {
if (document != null && !indirectReference.getDocument().equals(document)) {
throw new PdfException(PdfException.PdfIndirectObjectBelongsToOtherPdfDocument);
}
if (indirectReference.getRefersTo() == null) {
write(PdfNull.PDF_NULL);
} else if (indirectReference.getGenNumber() == 0) {
writeInteger(indirectReference.getObjNumber()).
writeBytes(endIndirectWithZeroGenNr);
} else {
writeInteger(indirectReference.getObjNumber()).
writeSpace().
writeInteger(indirectReference.getGenNumber()).
writeBytes(endIndirect);
}
}
つまり、2つの異なるドキュメントがあることを意味しますが、別のドキュメントをいつ作成したか分かりません。
