Code:

package com.example.carsharing.repository.entity;

import javax.persistence.*;
import lombok.Data;
import lombok.NoArgsConstructor;



@Entity
@Table(name = "CAR")
@Data
@NoArgsConstructor
public class Car {
  @Id
  @GeneratedValue
  @Column(name = "ID")
  Long ID;
  @Column(name = "car_name")
  String carName;
  @Column(name = "company_id")
  Long companyId;



  public Car(long ID, String carName, long companyId) {
      this.ID = ID;
      this.carName = carName;
      this.companyId = companyId;
  }
}

    This is the answear posting by Turing85

    In case Car is annotated with @Entity, please ensure that it uses the correct Entity annotation (for spring-boot 2.x, it should come from package javax; for spring-boot 3.x, it should come from package jakarta). – Turing85

    Too hard to go to the link. But you are probably missing an @Entity annotation on Car
