IText 5.5.11和thymeleaf：阿拉伯字符

Question

我正在使用HTML格式转换PDF文件来自Itext 5.5.11和ITextRenderer的阿拉伯语文本转换，但这些字母是颠倒的

我试着按照这个问题的答案， Arabic characters from html content to pdf using iText

但问题总是摆出来

我的功能就像：

public void createPdf(String templateName, Map map) throws Exception {
        Assert.notNull(templateName, "The templateName can not be null");
        Context ctx = new Context();
        if (map != null) {
            Iterator itMap = map.entrySet().iterator();
            while (itMap.hasNext()) {
                Map.Entry pair = (Map.Entry) itMap.next();
                ctx.setVariable(pair.getKey().toString(), pair.getValue());
            }
        }

        String processedHtml = templateEngine.process(templateName, ctx);
        FileOutputStream os = null;
        //String fileName = UUID.randomUUID().toString();
        try {
            // final File outputFile = File.createTempFile(fileName, ".pdf");
            os = new FileOutputStream(new File(directoryPathConfig.getPathDefaultDirectory("pdfOutput.path")).getAbsolutePath() + "/World.pdf");
            ITextRenderer renderer = new ITextRenderer();
            renderer.setDocumentFromString(processedHtml,new ClassPathResource("/static/").getURL().toExternalForm());
            renderer.getFontResolver().addFont("fonts/NotoNaskhArabic-Regular.ttf", "Noto Naskh Arabic", BaseFont.IDENTITY_H, BaseFont.EMBEDDED, null);
            renderer.layout();
            renderer.createPDF(os, false);

            renderer.finishPDF();
            System.out.println("PDF created successfully");
        }
        finally {
            if (os != null) {
                try {
                    os.close();
                } catch (IOException e) { /*ignore*/ }
            }
        }
    }

在我的模板中，我这样做了：

<p dir="rtl" style="font-family: Noto Naskh Arabic;text-align: center;text-decoration: underline; font-size: 18px;">الشباك الوحيد للجماعة</p>
