java.lang.IllegalArgumentException：不是託管類型

我正在使用Spring boot和jpa。它是here java.lang.IllegalArgumentException：不是託管類型

我有一個看起來像這樣的域名。此外，似乎Entity註釋已棄用，因此我正在使用DynamicUpdate。

@Data 
@AllArgsConstructor 
@NoArgsConstructor 
@DynamicUpdate 
public class Person { 
    private String id; 
    private String name; 
}

我SpringBootApplication類看起來像這樣

@SpringBootApplication 
@ComponentScan("com.lapots.breed.platform.cloud.boot") 
@EnableJpaRepositories("com.lapots.breed.platform.cloud.boot.repository") 
@EntityScan("com.lapots.breed.platform.cloud.boot.domain") 
public class JavaCloudSampleApplication { 

    public static void main(String[] args) { 
     SpringApplication.run(JavaCloudSampleApplication.class, args); 
    } 

    // executed after all beans instantiated 
    @Bean 
    public CommandLineRunner data(PersonRepository repository) { 
     return (args) -> { 
      repository.save(new Person(UUID.randomUUID().toString(), "Nike")); 
     }; 
    } 
}

repository類看起來像這樣

@Repository 
public interface PersonRepository extends JpaRepository<Person, String> { 
}

使用這個類看起來像這樣

@Service 
@Transactional 
public class PersonService implements IPersonService { 

    @Autowired 
    private PersonRepository personRepository; 

    @Override 
    public Person findPerson(String id) { 
     return personRepository.findOne(id); 
    } 

    @Override 
    public Person generatePerson() { 
     Person person = new Person(); 
     person.setId(UUID.randomUUID().toString()); 
     person.setName("Nike"); 
     return person; 
    } 
}

但是當我啓動應用程序，我得到的錯誤

問題是什麼？

你從哪裏找到「@實體」被棄用的聲明？因爲'不是託管類型'基本上意味着缺少'@ Entity'。 –

'hibernate'的'實體'註釋 - 不是'javax.persistence'已被棄用 – lapots

但是'Hibernate'' @ Entity'只是'JPA'的擴展。所以如果你將'JPA'添加到'Person'，你應該沒問題。 –

也許Person需要Entity註釋，因爲您使用的是JPA。

@Entity 
@Data 
@AllArgsConstructor 
@NoArgsConstructor 
@DynamicUpdate 
public class Person { 
    private String id; 
    private String name; 
}

的確，「實體」丟失了。我由於某些原因排除了'javax.persistence'，所以我沒有'javax.persistence.Entity'可用 – lapots
