Spring JPA (Hibernate) Aucun bean qualifié de type: javax.persistence.EntityManagerFactory

J'utilise Spring-boot, donc une guerre déployée dans Tomcat 7. Lorsque je démarre l'application, j'obtiens ce qui suit:

Voici comment démarre mon application:

@Configuration
@ComponentScan
@EnableAutoConfiguration
public class Application {

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

Lorsque mon contrôleur Spring gère la connexion:

@Controller
public class GetController {

    private UserService userService;

    @Autowired 
    public void setUserService(UserService userService) {
        this.userService = userService;
    }

    @RequestMapping(value = "/user", method = RequestMethod.GET)
    public @ResponseBody User getUser(@RequestParam(value="id", required=true) int id) {
        User user = null;

        user = userService.getUser(id);

        return user;
    }
}

Il fait un getUser sur le userService:

@Component
public class UserService {

    private UserDAO UserDao;

    public UserDAO getUserDao() {
        return UserDao;
    }

    @Autowired
    public void setUserDao(UserDAO UserDao) {
        this.UserDao = UserDao;
    }

    public User getUser(int id) {
        return getUserDao().load(id);
    }
}

Qui utilise userDao pour trouver l'entité:

@Repository("userDao")
@Transactional(propagation=Propagation.REQUIRED)
public class UserDAO {

    @PersistenceContext
    private EntityManager entityManager;

    public void insert(User user) {
        entityManager.persist(user);
    }

    public User load(int id) {
        return entityManager.find(User.class, id);
    }
}

J'ai le spring-config.xml suivant dans/src/main/resources:

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:aop="http://www.springframework.org/schema/aop"

        <property name="username" value="my_user" />
        <property name="password" value="" />
    </bean>
</beans>

Et enfin et surtout, le fichier /src/main/resources/persistence.xml suivant:

<?xml version="1.0" encoding="UTF-8"?>
<persistence xmlns="http://Java.Sun.com/xml/ns/persistence"
    version="1.0">
    <persistence-unit name="userPersistenceUnit" transaction-type="RESOURCE_LOCAL" >
    <class>com.mydomain.orm.User</class>
</persistence-unit>
</persistence>

Que dois-je faire pour résoudre cette erreur?

Vous voulez un EntityManager injecté, mais vous n'avez aucune annotation d'injection sur le terrain, et "factory" n'est pas le bon qualificatif dans tous les cas. Annotez votre champ avec @PersistenceContext, En utilisant unitName si nécessaire pour faire la distinction entre plusieurs unités de persistance.

Réponse à la question modifiée: Votre fichier XML n'est pas inclus, car vous commencez à partir de la classe Application, et Spring suit simplement le @ComponentScan À partir de là. Ajoutez cette importation à votre classe Application (ou à toute classe @Configuration Scannée):

@ImportResource("classpath:spring-config.xml")

Vous pouvez également migrer votre configuration XML vers le format JavaConfig, que Spring analysera en tant que composant.

Votre problème est que vous utilisez une configuration d'annotation qui recherche déjà le chemin de classe pour les beans annotés, cela tente d'instancier la UserDAO mais vous ne fournissez pas d'entitéManagerFactory ici.

Vous pouvez combiner JavaConfig avec la configuration XML via @ImportResource("classpath:spring-config.xml").


@Configuration
@ComponentScan
@EnableAutoConfiguration
@ImportResource("classpath:spring-config.xml")
public class Application {

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


@Controller
public class GetController {
    @Autowired
    UserService userService;

    @RequestMapping(value = "/user", method = RequestMethod.GET)
    public @ResponseBody User getUser(@RequestParam(value="id", required=true) int id) {

        return userService.getUser(id);
    }
}



@Component
public class UserService {

    @Autowired
    private UserDAO UserDao;

    public User getUser(int id) {
        return getUserDao().load(id);
    }
}

Puis-je suggérer d'utiliser SpringData pour le DAO, vous économiserez beaucoup de code standard.

En regardant le rapport de configuration automatique qui est sorti du crash, je peux voir qu'il n'y a pas de DataSource défini. Spring Boot en créera un pour vous si vous avez les bonnes choses sur votre chemin de classe - par exemple au minimum pour que quelque chose fonctionne, incluez h2 ou hsqldb sur votre chemin de classe.

Par ailleurs, le fichier XML est redondant si vous utilisez Spring Boot de la bonne façon.
