java.lang.IllegalArgumentException: Kein verwalteter Typ

Question

Ich verwende Spring boot und jpa. Es ist here

Ich habe eine Domain, die so aussieht. Auch scheint es Entity Annotation ist veraltet, so verwende ich DynamicUpdate stattdessen.

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

Meine SpringBootApplication Klasse sieht wie folgt aus

@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 Klasse wie dieses

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

service sieht, dass diese Klasse sieht wie folgt aus

verwendet

@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; 
    } 
} 

Aber

wenn ich Anwendung zu starten erhalte ich die Fehler

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'personService': Unsatisfied dependency expressed through field 'personRepository'; nested exception is org.springframework.beans.factory.BeanCreationException: Error

Was ist das Problem?

Answer 1

Vielleicht Person benötigt die Entity Annotation, da Sie JPA verwenden.

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