总结：
对象必须是javaBean,用集合测试是不可以

//通过Map 文件
	public static void main(String[] args) {
//InputStream in = new ByteArrayInputStream(str.getBytes());
//	InputSource inputSource = new InputSource(in);
		QQ   qq = new QQ();
		qq.setId(1);

		try {
			Mapping mapping =new Mapping();
			mapping.loadMapping("D:/map.xml");
			Writer writer = new FileWriter("D:/qq.xml");
			Marshaller  marshaller =new Marshaller(writer);
			marshaller.setMapping(mapping);
			marshaller.marshal(qq);
			
			
			Reader reader  = new FileReader("D:/qq.xml");
			Unmarshaller unmarshaller =new Unmarshaller(mapping);
			QQ qq1=(QQ) unmarshaller.unmarshal(QQ.class,reader);
			System.out.println("id="+qq.getId()+"--"+qq.getName());

		} catch (Exception e) {
