   也可以变通一下解决这个问题：
   在DubboReference注解上加 
parameters参数，同一个服务接口不同的Reference注解定义不同的参数，比如定义一个process参数，clientA用proc-a, 
clientB用proc-b：
   ```
   ClientA.java:
   @DubboReference( parameters = {"process", "proc-a"}, ...)
   DubboService s;
   ...
   ClientB.java:
   @DubboReference( parameters = {"process", "proc-b"}, ...)
   DubboService s;
   ```
   
clientA和clientB的回调方法放到统一的门面组件里，回调方法依据rpccontext的consumerUrl里取出process参数分别进行处理，比如：
   ```
   String process = 
RpcContext.getContext().getConsumerUrl.getParameter("process");
   switch (process) {
       case "proc-a": ....
       case "proc-b": ....
   }
   ```
