   @jiangdongzi 自己给函数加noexcept声明即可，可以避免业务代码的异常抛到框架中。
   
   比如service接口的函数:
   ```cpp
       virtual void Echo(google::protobuf::RpcController* cntl_base,
                         const EchoRequest* request,
                         EchoResponse* response,
                         google::protobuf::Closure* done) noexcept {
      }
   ```
   以及这个接口所调用的各种函数。你觉得可能抛异常的都加上。
   C++在异常抛出的链路上遇到首个noexcept声明的地方，就会立刻停止继续往上抛异常，保留此时的栈信息。所以noexcept离实际core的位置越近越准。这个bRPC使用者自己把握即可。兜底的方式是给service接口自行加上noexcept声明。
