   我按照负载均衡自定义了LoadBalance，配置了
   <dubbo:reference  interface="xxx.xxx.autocharge.service.AutoChargeService" loadbalance="demo"/>
   注入bean
    @Reference
     AutoChargeService autoChargeService;
   再调用autoChargeService的方法时发现自定义扩展的loadbalance还是没有生效通过debug发现
   在org.apache.dubbo.rpc.cluster.support.AbstractClusterInvoker#initLoadBalance方法中
   这一段调用
   ExtensionLoader.getExtensionLoader(LoadBalance.class).getExtension(invokers.get(0).getUrl()
                       .getMethodParameter(RpcUtils.getMethodName(invocation), LOADBALANCE_KEY, DEFAULT_LOADBALANCE));
   通过getMethodParameter获取到的loadbalance的值是空的所以使用了默认的RandomLoadBalance，于是我强制修改变量，将
   getExtension（）的参数修改为自定义的loadbalance的名称，结果生效了
   ,所以我初步定位是在注册时没有把loadbalance的值放进去URL.parameters里面导致的，使用的dubbo版本是2.7.3的
   这个loadbalance是需要consumer和provider两边都要配置才行吗？
