[Spring] 스프링 내가 생성한 빈(Bean) 객체 정보 조회하기

package hello.core;

import hello.core.member.Grade;
import hello.core.member.Member;
import hello.core.member.MemberService;
import hello.core.member.MemberServiceImpl;
import hello.core.order.Order;
import hello.core.order.OrderService;
import hello.core.order.OrderServiceImpl;
import org.junit.jupiter.api.DisplayName;
import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.config.BeanDefinition;
import org.springframework.context.annotation.AnnotationConfigApplicationContext;

public class AutoAppConfigTest {

    private final String packageName = "hello.core";
    AnnotationConfigApplicationContext ac = new AnnotationConfigApplicationContext(AutoAppConfig.class);

    @Test
    @DisplayName("빈 설정 메타정보 확인")
    void findApplicationBean() {
        String[] beanDefinitionNames = ac.getBeanDefinitionNames();
        for(String beanDefinitionName : beanDefinitionNames){
            BeanDefinition beanDefinition = ac.getBeanDefinition(beanDefinitionName);

            if(beanDefinition.getRole() == BeanDefinition.ROLE_APPLICATION && beanDefinition.toString().contains(packageName) == true) {
                System.out.println("beanDefinitionName = " + beanDefinitionName + " beanDefinition = " + beanDefinition);
            }
        }
    }
}

기본적으로 생성되는 Bean + 내가 만든 Bean = 전체 Bean 정보 

전체 Bean 정보에서 해당 Bean Class 정보가 내 패키지에서 만들어진 것인지 체크해서 보여준다)
