Я хочу создать pdf файл с использованием iText 7, но что-то не так:
com.itextpdf.kernel.PdfException: Pdf indirect object belongs to other PDF document. Copy object to current pdf document.

мой код:
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
}
}
Мой единственный код для стиля в iText7:
private PdfFont bfChinese = null;
будет инициализирован в вызываемом конструкторе службы.
public GeneratePDFService() {
String PdfFontPath = EnvironmentUtils.getClasspathFilePath("font/MSYH.TTF");
try {
bfChinese = PdfFontFactory.createFont(PdfFontPath, "Identity-H", true);
} catch (Exception e) {
e.printStackTrace();
}
}
Я пробовал установить мой шрифт как
static
, но это не помогает.
В этом месте я получаю exception:
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);
}
}
Это означает, что у меня два разных документа, но я не знаю каким образом я создал второй документ. Заранее благодарю за помощь!
