读取XML报错java.net.MalformedURLException: no protocol

		// 数据所请求数据
        String xmlData = request.getParameter("request");
		SAXReader saxReader = new SAXReader();
        try {
   		// Document document = saxReader.read(xmlData)
		// 读取xml数据为Document对象
            Document document = saxReader.read(new ByteArrayInputStream(xmlData.getBytes()));
            System.out.println(document);
        } catch (DocumentException e) {
            log.error("解析用户xml数据失败: " + e.getMessage(), e);
        }

Document document = saxReader.read(xmlData)，这样读取xml数据会报上述错误，需要使用如下方式读取：Document document = saxReader.read(new ByteArrayInputStream(xmlData.getBytes()));
