@Test
public void lifeCycleTest() {
    ConfigurableApplicationContext ac = new AnnotationConfigApplicationContext(LifeCycleConfig.class);
    NetworkClient client = ac.getBean(NetworkClient.class);
    ac.close();
}

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

여기에서 setUrl을 통해서 url을 지정했는대 ac.getBean(NetworkClient.class)에서는 왜 null이 나오는건지 잘 모르겠습니다.
