使用场景：

接收XML格式的报文，转换成java实体对象

报文示例

<?xml version="1.0" encoding="utf-8"?>

需要使用到的工具类方法

	/**
	 * 将获取的xml文件数据流，转换成String类型
	 * 
	 * @param bufferedReader 输入流文本缓冲字符
	 * @return StringBuffer 字符缓存
	 */
	private StringBuffer transferInputToString(BufferedReader bufferedReader) {

		StringBuffer xml = new StringBuffer("");

		if (bufferedReader == null)
			return xml;

		try {
			String line = null;
			while ((line = bufferedReader.readLine()) != null) {
				xml.append(line);
			}
		} catch (IOException e) {
			exlog("读取的xml文件进行转换出错！", e);
		}

		return xml;
	}





	/**
	 * xml文件转换Bean对象
	 * 
	 * @param clazz
	 * @param xmlStr
	 * @return
	 */
	public static Object xml2Bean(Class clazz, String xmlStr) {
		Object xmlObject = null;
		try {
			JAXBContext context = JAXBContext.newInstance(clazz);
			Unmarshaller unmarshaller = context.createUnmarshaller();
			StringReader sr = new StringReader(xmlStr);
			xmlObject = unmarshaller.unmarshal(sr);
		} catch (JAXBException e) {
			e.printStackTrace();
		}
		return xmlObject;
	}

操作xml报文文件

FileInputStream fis = new FileInputStream("D:\\vehicle.xml");
BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(fis));
StringBuffer strResponseXML = transferInputToString(bufferedReader);
String resultXml = strResponseXML.toString();
PrpDCarModelInfos carInfos = PrpDCarModelInfos carInfos = (PrpDCarModelInfos) XmlUtil.xml2Bean(PrpDCarModelInfos.class, resultXml);
Head head = carInfos.getHead();
String respCode = head.getResponseCode();
String errCode = head.getErrorCode();
Body body = carInfos.getBody();
List<PrpDCarModelInfo> list = body.getCarModelInfoList();
