   1）	配置xml文件：在comsumer.xml中application name属性定义了应用名
   <dubbo:application name="demo-provider"/>
   2）  RpcContext: RpcContext中存在attachments字段，以key-value的形式支持开发者扩展字段值。
   3)   ComsumerContextFilter的invoke()方法中调用RpcContext.setAttachment()方法，“application”为key, application name为value封装在RpcContext的扩展字段attachments中,如下：
   .setAttachment(Constants.APPLICATION_KEY, invoker.getUrl().getParameter("application"))
   4）服务提供方Provider从RpcContext取出application name即可
