我试图在我使用FlyingSaucer(https://github.com/flyingsaucerproject/flyingsaucer)从HTML文件创建的PDF文件中设置元数据(例如标题或作者)。
这是创建PDF文件的代码:
ByteArrayOutputStream out = new ByteArrayOutputStream();
ITextRenderer renderer = new ITextRenderer();
renderer.getFontResolver().addFont("fonts/VERDANA.TTF", BaseFont.IDENTITY_H, BaseFont.EMBEDDED);
renderer.getFontResolver().addFont("fonts/VERDANAB.TTF", BaseFont.IDENTITY_H, BaseFont.EMBEDDED);
renderer.getFontResolver().addFont("fonts/VERDANAI.TTF", BaseFont.IDENTITY_H, BaseFont.EMBEDDED);
renderer.getFontResolver().addFont("fonts/VERDANAZ.TTF", BaseFont.IDENTITY_H, BaseFont.EMBEDDED);
renderer.setDocumentFromString(... HTML as a String ...);
renderer.layout();
renderer.createPDF(out);
FileOutputStream fos = new FileOutputStream(pathPdf);
PdfReader reader = new PdfReader(baos.toByteArray());
PdfStamper stamper = new PdfStamper(reader, fos);
... sets watermark image if available ...
stamper.close();
reader.close();
我尝试过获取PdfDictionary并设置元数据,获取信息图并设置元数据,并获取文档来设置元数据,但我无法使其工作。

您可以更轻松地进行操作。实质是让作者成为createPdf方法之后的对象,并且在创建pdf时一定不要关闭文档,而必须在最后手动进行:
ITextRenderer renderer = new ITextRenderer();
renderer.setDocumentFromString(html);
renderer.layout();
renderer.createPDF(outputStream, false);
renderer.getWriter().getInfo().put(PdfName.CREATOR, new PdfString("witek"));
renderer.finishPDF();

找到解决方案:
ByteArrayOutputStream out = new ByteArrayOutputStream();
ITextRenderer renderer = new ITextRenderer();
renderer.getFontResolver().addFont("fonts/VERDANA.TTF", BaseFont.IDENTITY_H, BaseFont.EMBEDDED);
renderer.getFontResolver().addFont("fonts/VERDANAB.TTF", BaseFont.IDENTITY_H, BaseFont.EMBEDDED);
renderer.getFontResolver().addFont("fonts/VERDANAI.TTF", BaseFont.IDENTITY_H, BaseFont.EMBEDDED);
renderer.getFontResolver().addFont("fonts/VERDANAZ.TTF", BaseFont.IDENTITY_H, BaseFont.EMBEDDED);
renderer.setDocumentFromString(... HTML as a String ...);
renderer.layout();
renderer.createPDF(out);
FileOutputStream fos = new FileOutputStream(pathPdf);
PdfReader reader = new PdfReader(baos.toByteArray());
PdfStamper stamper = new PdfStamper(reader, fos);
... sets watermark image if available ...
PdfDictionary info = reader.getTrailer().getAsDict(PdfName.INFO);
info.getKeys().forEach((k) -> {
System.out.println("k: " + k + ", v:" + info.get((PdfName) k));
});
info.put(PdfName.TITLE, new PdfString("Title", PdfObject.TEXT_UNICODE));
info.put(PdfName.AUTHOR, new PdfString("Author", PdfObject.TEXT_UNICODE));
stamper.close();
reader.close();
