Spring Boot 웹개발 Entity 상속관계 만들기

import jakarta.persistence.MappedSuperclass;
import lombok.Getter;
import org.springframework.data.annotation.CreatedDate;
import org.springframework.data.annotation.LastModifiedDate;

import java.time.LocalDateTime;

@Getter
@MappedSuperclass
public abstract class BaseTimeEntity {

    @CreatedDate
    private LocalDateTime createdAt;

    @LastModifiedDate
    private LocalDateTime updatedAt;
}

JPA에서 제공하는 create, update time을 사용한 BaseTimeEntity class

 

import jakarta.persistence.MappedSuperclass;
import lombok.Getter;
import org.springframework.data.annotation.CreatedBy;
import org.springframework.data.annotation.LastModifiedBy;

@Getter
@MappedSuperclass
public abstract class BaseAuditEntity extends BaseTimeEntity {

    @CreatedBy
    private Long createdBy;

    @LastModifiedBy
    private Long updatedBy;
}

 

import jakarta.persistence.GeneratedValue;
import jakarta.persistence.GenerationType;
import jakarta.persistence.Id;
import jakarta.persistence.MappedSuperclass;
import lombok.Getter;

@Getter
@MappedSuperclass
public abstract class BaseEntity extends BaseAuditEntity {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;
}

 

Entity에서 BaseEntity를 상속받아 사용한다
