어노테이션으로 빈등록 및 @Autowired 해주기

package hello.hellospring.controller;

import hello.hellospring.service.MemberService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;

@Controller
public class MemberController {

    private MemberService memberService;

    @Autowired
    public MemberController(MemberService memberService) {
        this.memberService = memberService;
    }
}

 

생성자로 Service를 받아와서 받아온 Service를 this 문법으로 할당해주는 모습. 이렇게 하면 Autowired 된다.
