java实现物流实时跟踪

- 输入快递单号或物流单号，点击查询。查看物流/快递实时信息
- 通过快递鸟第三方API进行实现

快递鸟官网：http://www.kdniao.com/

注册成功之后 ，按照提示的信息，依次把信息填写完整，点击提交申请即可。就可以看到 商户ID 和 API key
 等信息，有这些信息就可以请求查询等其他的接口Api

快递鸟优势：免费号，初创企业每天3000次免费查询；可查询国内外、300多家快递物流信息
系统扩展：只需填写单号，自动追踪查询物流

即时查询API
	根据快递单号和快递公司编码实时查询物流轨迹信息，即时返回状态后完成查询。
	申请快递鸟API接口网址： http://www.kdniao.com/YundanChaxunAPI.aspx
物流跟踪API
	自营商城、电商平台及ERP等将运单信息及收派件地址信息订阅快递鸟，快递鸟系统定时推送新的物流轨迹信息
	直至运单被签收。
在途监控API
	提供物流订单监控服务，用户将订单内容订阅到快递鸟对订单进行实时监控，当物流轨迹有更新时实时反向推送
	返回，并对数据进行格式化，计算运单：预计到达时间、全流程的物流状态（无轨迹、已揽收、在途中、已签
	收、问题件、到达派件城市、派件中、快递柜或驿站签收、超时未更新、超时为签收、拒签/退件）、当前所在
	城市等数据后，推送给用户，监控直到订单签收后结束。 支持即时查询模式与订阅模式。
