All Implemented Interfaces:

implements EndpointFactory

                一些约定：
 
                1） service :
                        1.1） not share channel :  某个service暴露服务的时候，不期望和别的service共享服务，明哲自保，比如你说：我很重要，我很重要。
 
                        1.2） share channel ： 某个service 暴露服务的时候，如果有某个模块，但是拆成10个接口，可以使用这种方式，不过有一些约束条件：接口的几个serviceConfig配置需要保持一致。
                                
                                不允许差异化的配置如下：
                                        protocol, codec , serialize, maxContentLength , maxServerConnection , maxWorkerThread, workerQueueSize, heartbeatFactory
                                
                2）心跳机制：
 
                        不同的protocol的心跳包格式可能不一样，无法进行强制，那么通过可扩展的方式，依赖heartbeatFactory进行heartbeat包的创建，
                        同时对于service的messageHandler进行wrap heartbeat包的处理。 
 
                        对于service来说，把心跳包当成普通的request处理，因为这种heartbeat才能够探测到整个service处理的关键路径的可用状况
