	/**
	 * 请求参数,XML 格式请求串
	 */
	private String req;
	/**

	 */
	private String sign;

	private String platformNo;

	/**

	/**

	@XmlAttribute
	public String getPlatformNo() {
		return platformNo;
	}

	public void setPlatformNo(String platformNo) {
		this.platformNo = platformNo;
	}

	@XmlElement
	public int getPlatformUserNo() {

	}

	public void setPlatformUserNo(int platformUserNo) {

	}

	@XmlElement

	public void setReq(String req) {

	public void setSign(String sign) {

	}

	@XmlElement

	}

	public void setCallbackUrl(String callbackUrl) {

	}

	@XmlElement

	}

	public void setNotifyUrl(String notifyUrl) {

	}

	public String getYeePayAction() {
		return yeePayAction;

	public void setYeePayAction(String yeePayAction) {

	}

}

xml和java对象转换器如下：

	public <T> T toObject(String respXml,Class<T> c) {
		try {
			JAXBContext context = JAXBContext.newInstance(c);
			javax.xml.bind.Unmarshaller unmarshaller = context
					.createUnmarshaller();
			StringReader reader = new StringReader(respXml);
			return (T) unmarshaller.unmarshal(new StreamSource(reader));
		} catch (Exception e) {
			LOG.error(e.getMessage(),e);
			e.printStackTrace();
			throw new RuntimeException(e.getMessage(),e);
		}
	}

	public String toXml(Object req,Class<?> c) {
		try {
			StringWriter writer = new StringWriter();
			JAXBContext context = JAXBContext.newInstance(c);
			javax.xml.bind.Marshaller marshaller = context.createMarshaller();
			marshaller.marshal(req,new StreamResult(writer));
			return writer.toString();
		} catch (Exception e) {
			LOG.error(e.getMessage(),e);
		}
	}
