Почему добавление @EnableAutoConfiguration приводит к сбою весенней загрузки с «Невозможно найти пакеты JPA для сканирования»

Question

Почему добавление @EnableAutoConfiguration к следующему загрузочному приложению приводит к тому, что он не создает entityManagerFactory? Если я удалю @EnableAutoConfiguration все работает нормально. Может ли кто-нибудь пролить свет на это поведение?

Любые советы оценили.

Answer 1

Это потому, что Spring Boot хочет создавать репозитории для вас, и вы не сказали, где они находятся. Для этого вам нужен @ComponentScan (думаю, сообщение об ошибке говорит, по крайней мере, в последних версиях). Ваше приложение делает много всего, что ему не нужно. Это должно работать:

@Configuration 
@EnableAutoConfiguration 
@ComponentScan("test.builder") 
public class BootApp implements CommandLineRunner { 

    private static Logger logger = LoggerFactory.getLogger(BootApp.class); 

    @Autowired 
    private BuilderRepository repository; 

    @Override 
    public void run(String... args) { 
     Builder builder = repository.findOne(10);  
     logger.info("Retrieved ", builder.toString()); 
    } 

    public static void main(String[] args) { 

     SpringApplication.run(BootApp.class, args); 

    } 

} 

Answer 2

Где ваши интерфейсы @Repository?

Данные Spring могут создавать для вас реализации @Repository интерфейсов различных ароматов. Spring Boot будет обрабатывать все это для вас, если эти @Repositories включены в один и тот же пакет (или подпакет) вашего класса @EnableAutoConfiguration.
