Xml轉換Java Bean

工具類
/**
 * 將XML轉為指定的POJO
 * @param clazz
 * @param xmlStr
 * @return
 * @throws Exception
 */
public static Object xmlStrToOject(Class<?> clazz, String xmlStr) throws Exception {
    Object xmlObject = null;
    Reader reader = null;
    try{
        JAXBContext context = JAXBContext.newInstance(clazz);

        // XML 轉為對象的接口
        Unmarshaller unmarshaller = context.createUnmarshaller();

        reader = new StringReader(xmlStr);
        xmlObject = unmarshaller.unmarshal(reader);

        if (null != reader) {
            reader.close();
        }
    }catch (Exception e){e.printStackTrace();}


    return xmlObject;
}

使用工具類
Vehicle vehicle = (Vehicle)XmlUtil.xmlStrToOject(Vehicle.class,xmlStr);

String str = vehicle.getCamID().get(0);

測試

public static void main(String[] args) {
   String xmlStr = "<?xml version=\"1.0\" encoding=\"utf-8\"?>\n" +
           "\n" +
           "<Vehicle> \n" +
