            NetworkClient networkCilent = new NetworkClient();
            networkCilent.setUrl("http://hello-spring.dev");
            networkCilent.connent();
            return networkCilent;
        }
    }
}

LifeCycleConfig에서 초기화 콜백 안쓰고도setUrl을 설정하고 나서connect를 호출하면 url이 잘호출되는데 ,,,초기화호출을 쓰는 이유가 있나요? connect호출시점이 setUrl다음에 오기만 하면 되니깐 이렇게 작성해도될거같아서요
