本文介绍了一种使用Java从远程URL抓取网页并将其转换为PDF文件的方法。通过使用iText库，结合HTTP URL连接获取HTML内容，再利用XMLWorker解析HTML并写入PDF中。文中还列举了必要的Maven依赖项。

String urlPath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+request.getContextPath() +"/ssl/test.htm";
			 URL url = new URL(urlPath);  
	         URLConnection rulConnection = url.openConnection();  
	         HttpURLConnection httpUrlConnection = (HttpURLConnection) rulConnection; 
			
			 // step 1
	        Document document = new Document();
	        // step 2
	        PdfWriter writer = PdfWriter.getInstance(document, new FileOutputStream("D:/TEST.pdf"));
	        // step 3
	        document.open();
	        // step 4
	        XMLWorkerHelper.getInstance().parseXHtml(writer, document,httpUrlConnection.getInputStream(), Charset.forName("UTF-8"));
	        // step 5
	        document.close();
