Itext7 生成 pdf,但有例外“Pdf 间接对象属于其他 PDF 文档。将对象复制到当前 pdf 文档。
我想用itext 7生成一个pdf,但是一些错误发生在我们身上:
com.itextpdf.kernel.PdfException: Pdf indirect object belongs to other PDF document. Copy object to current pdf document.

我的生成代码 :
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
}
}
我在 itext7 中唯一的样式代码:
private PdfFont bfChinese = null;
将在服务构造函数中调用 init:
public GeneratePDFService() {
String PdfFontPath = EnvironmentUtils.getClasspathFilePath("font/MSYH.TTF");
try {
bfChinese = PdfFontFactory.createFont(PdfFontPath, "Identity-H", true);
} catch (Exception e) {
e.printStackTrace();
}
}
我尝试将我的字体设置为静态,但不起作用。
这是地方抛出异常:
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);
}
}
这意味着我有两个不同的文档,但我不知道什么时候我创建了另一个文档。提前感谢您的建议。
