Spring data jpa- Aucun bean nommé ‘entityManagerFactory’ n’est défini; L’dependency injections automatiques a échoué

Je suis en train de développer une application utilisant des données printanières jpa, hibernate, mysql, tomcat7, maven et cela crée une erreur. J’essaie de le comprendre mais j’ai échoué.

error are Impossible de résoudre la référence au bean ‘entityManagerFactory’ lors de la définition de l’argument constructeur. Aucun bean nommé ‘entityManagerFactory’ n’est défini; L’dependency injections automatiques a échoué

RoleRepository est

 import org.springframework.data.jpa.repository.JpaRepository; import org.wahid.cse.entity.Role; public interface RoleRepository extends JpaRepository{ }

Spring Data JPA recherche par défaut un entityManagerFactory nommé entityManagerFactory . Découvrez cette partie de la Javadoc de EnableJpaRepositories ou du Table 2.1 de la documentation de Spring Data JPA.

Cela signifie que vous devez renommer votre bean entityManagerFactory en entityManagerFactory ou modifier votre configuration Spring pour:

(si vous utilisez XML)

@EnableJpaRepositories(basePackages="your.package", entityManagerFactoryRef="emf")

(si vous utilisez Java Config)

Dans le contexte de votre application, changez le bean avec l’ID de entityManagerFactory en entityManagerFactory :

      true create org.hibernate.dialect.MySQLDialect

      true create org.hibernate.dialect.MySQLDialect

J’ai eu ce problème après la migration de spring-boot-starter-data-jpa ver. 1.5.7 à 2.0.2 (de l’ancien hibernation à l’hibernation 5.2). Dans ma classe de @Configuration , j’ai injecté entityManagerFactory et transactionManager .

 //I've got my data source defined in application.yml config file, //so there is no need to configure it from java. @Autowired DataSource dataSource; @Bean public LocalContainerEntityManagerFactoryBean entityManagerFactory() { //JpaVendorAdapteradapter can be autowired as well if it's configured in application properties. HibernateJpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter(); vendorAdapter.setGenerateDdl(false); LocalContainerEntityManagerFactoryBean factory = new LocalContainerEntityManagerFactoryBean(); factory.setJpaVendorAdapter(vendorAdapter); //Add package to scan for entities. factory.setPackagesToScan("com.company.domain"); factory.setDataSource(dataSource); return factory; } @Bean public PlatformTransactionManager transactionManager(EntityManagerFactory entityManagerFactory) { JpaTransactionManager txManager = new JpaTransactionManager(); txManager.setEntityManagerFactory(entityManagerFactory); return txManager; }

Rappelez-vous également d’append la dépendance hibernate-entitymanager à pom.xml, sinon EntityManagerFactory ne sera pas trouvé dans classpath:

  org.hibernate hibernate-entitymanager 5.0.12.Final

Je pense que cela est lié à la nouvelle version de Spring boot plus utilisant des données de spring JPA remplace simplement l’annotation @Bean sur public LocalContainerEntityManagerFactoryBean entityManagerFactory () à @Bean (name = “entityManagerFactory”)

Déterminer le nom du haricot devrait résoudre le problème
