FileOutputStream outputStream=null; try{ outputStream=new FileOutputStream(saveFilePath); PdfWriter writer = new PdfWriter(saveFilePath); PdfDocument pdfDoc = new PdfDocument(writer); pdfDoc.setDefaultPageSize(PageSize.A4); ConverterProperties converterProperties = new ConverterProperties(); FontProvider provider = new FontProvider(); provider.addFont("D:/home/file/static/fonts/SourceHanSansCN-Regular.otf"); provider.addStandardPdfFonts(); provider.addSystemFonts(); PdfFont pdfFont = PdfFontFactory.createFont("D:/home/file/static/fonts/SourceHanSansCN-Regular.otf",BaseFont.IDENTITY_H,true); converterProperties.setFontProvider(provider); converterProperties.setCharset("UTF-8"); pdfDoc.addEventHandler(PdfDocumentEvent.END_PAGE, new PDFBuilder(pdfFont,title,pdfTime,footLabel)); Document doc = HtmlConverter.convertToDocument(htmlData, pdfDoc, converterProperties); doc.close(); writer.close(); outputStream.close(); }catch(Exception ex){ throw new PDFException("PDF export to File fail",ex); }finally{ IOUtils.closeQuietly(outputStream); }中文斜体还是没有效果

根据你提供的代码，我看到你正在将HTML转换为PDF，然后将中文字体添加到PDF中。但是，我没有看到你在代码中设置中文字体为斜体。你需要在PDFBuilder类中设置中文字体为斜体，然后将其传递给PdfDocumentEvent.END_PAGE事件处理程序。例如：

public class PDFBuilder implements IEventHandler {
    private PdfFont font;
    private String title;
    private String pdfTime;
    private String footLabel;

    public PDFBuilder(PdfFont font, String title, String pdfTime, String footLabel) {
        this.font = font;
        this.title = title;
        this.pdfTime = pdfTime;
        this.footLabel = footLabel;
    }

    @Override
    public void handleEvent(Event event) {
        PdfDocumentEvent docEvent = (PdfDocumentEvent) event;
        PdfDocument pdfDoc = docEvent.getDocument();
        PdfPage page = docEvent.getPage();
        PdfCanvas canvas = new PdfCanvas(page.newContentStreamBefore(), page.getResources(), pdfDoc);

        Rectangle pageSize = page.getPageSize();
        canvas.beginText()
              .setFontAndSize(font, 12)
              .moveText(pageSize.getWidth() / 2 - 60, pageSize.getTop() - 20)
              .showText(title)
              .moveText(60, -pageSize.getTop() + 30)
              .showText(footLabel)
              .endText();

        canvas.beginText()
              .setFontAndSize(font, 10)
              .moveText(pageSize.getWidth() - 150, pageSize.getBottom() + 20)
              .showText(pdfTime)
              .endText();

        canvas.release();
    }
}

在这个例子中，我将PdfFont作为构造函数的参数传递给PDFBuilder类。在PDFBuilder类中，我使用setFontAndSize方法将PdfFont设置为斜体，并将其用于显示文本。你可以将这个PDFBuilder类传递给pdfDoc.addEventHandler（）方法，以便在PDF中显示中文字体的斜体效果。
