@Configuration 질문

package hello.core.lifecycle;

import org.junit.jupiter.api.Test;
import org.springframework.boot.test.context.TestConfiguration;
import org.springframework.context.ConfigurableApplicationContext;
import org.springframework.context.annotation.AnnotationConfigApplicationContext;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

public class BeanLifeCycleTest {

    @Test
    public void lifeCycleTest(){
        ConfigurableApplicationContext ac = new AnnotationConfigApplicationContext(LifeCycleConfig.class);

        System.out.println("1");
        NetworkClient client = ac.getBean(NetworkClient.class);
        System.out.println("2");
        ac.close();
    }


    @Configuration//
    static class LifeCycleConfig {
        @Bean
        public NetworkClient networkClient() {
            NetworkClient networkClient = new NetworkClient();
            networkClient.setUrl("http://hello-spring.dev");
            return networkClient;
        }
    }
}

여기서요,

LifeCycleConfig에 @Configuration이 붙으나 안붙으나,

AnnotationConfigApplicationContext에 인자로 주면 똑같은거 아닌가요?

Bean newworkClient 에 따로 스코프 설정도 안했으니까요...

아닌가요?
