스프링은 당신의 실체를 알지 못합니다.다음을 표시해야 합니다.MySpringBootApplication와 같은 부류의.@EntityScan("your.entities.package")

제 경우에는 그것이 없었습니다.@Entity그리고@Id엔티티 클래스의 주석입니다.

Repository 클래스와 동일한 Entity 클래스 모듈을 배치해야 합니다. 그렇지 않으면 @EntityScan을 애플리케이션 클래스에 추가해야 합니다.

setPackages를 사용하여 LocalContainerEntityManagerFactoryBean으로 엔티티 클래스 패키지를 구성해야 합니다.ToScan() 메서드입니다.아래의 예를 고려해 보십시오.

@Bean
public LocalContainerEntityManagerFactoryBean entityManagerFactory(DataSource dataSource, JpaVendorAdapter jpaVendorAdapter) {
    LocalContainerEntityManagerFactoryBean bean = new LocalContainerEntityManagerFactoryBean();
    bean.setDataSource(dataSource);
    bean.setJpaVendorAdapter(jpaVendorAdapter);
    bean.setPackagesToScan("your entity packaged name here");
    return bean;
}

저도 비슷한 문제에 직면한 적이 있지만, 당신의 코드에 대해서는 잘 모르겠지만 이 오류로 방문하는 다른 사람들을 위해 이 답변을 씁니다.아티팩트 ID와 그룹 ID(작은 오타)의 조합 외에 잘못된 패키지 이름을 지정하여 실수를 하였고 수정 시 문제가 해결되었습니다.

<code>
//if use builder you have to add package to scan 
@Primary
@Bean(name = "entityManagerFactory")
public LocalContainerEntityManagerFactoryBean entityManagerFactory(
EntityManagerFactoryBuilder builder
){
return builder
  .dataSource(dataSource())
  .packages("root path of package")
  .persistenceUnit("productenter code here")
  .build();

 }
</code>
