[되기시리즈 스프링부트3| 03장 스프링부트3 구조 이해하기]

1. 학습목표

스프링부트의 요청처리 과정을 이해할 수 있다.

2.필요 개념 문장정리

 3. 코드작성

package me.ggambo.springbootdeveloper;

import jakarta.persistence.*;
import lombok.AccessLevel;
import lombok.AllArgsConstructor;
import lombok.Getter;
import lombok.NoArgsConstructor;

@NoArgsConstructor(access = AccessLevel.PROTECTED)
@AllArgsConstructor
@Getter
@Entity
public class Member {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Column(name = "id", updatable = false)
    private Long id;
    @Column(name = "name", nullable = false)
    private String name;
}

package me.ggambo.springbootdeveloper;

import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.stereotype.Repository;

@Repository
public interface MemberRepository extends JpaRepository<Member, Long> {
}

package me.ggambo.springbootdeveloper;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

import java.util.List;

@RestController
public class TestController {

    @Autowired
    TestService testService;

    @GetMapping("/test")
    public List<Member> getAllMembers() {
        List<Member> members = testService.getAllMembers();
        return members;
    }
}

package me.ggambo.springbootdeveloper;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import java.util.List;

@Service
public class TestService {
    @Autowired
    MemberRepository memberRepository;

    public List<Member> getAllMembers() {
        return memberRepository.findAll();
    }
}

4. 마무리

스프링에 대해 공부한 내용을 정리를 하게 되었다.

큰 항목부터 학습하고 세부적으로 기록해야겠다.
