Question

Spring data jpa- не определен бин с именем entityManagerFactory; Инъекция автосвязанных зависимостей не удалась

Я разрабатываю приложение, используя Spring Data JPA, Hibernate, MySQL, Tomcat7, Maven, и это создает ошибку. Я пытаюсь выяснить это, но я не смог.

ошибка: не удается разрешить ссылку на bean-компонент "entityManagerFactory" при установке аргумента конструктора; Бин с именем entityManagerFactory не определен; Инъекция автосвязанных зависимостей не удалась

Решение

Возникла эта проблема при миграции весенней загрузки с 1.5.2 на 2.0.4. Вместо создания бобов я использовал @EnableAutoConfiguration в основном классе, и это решило мою проблему.

В контексте вашего приложения измените компонент с идентификатором из emf в entityManagerFactory:

<bean id="emf"
    class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
    <property name="packagesToScan" value="org.wahid.cse.entity" />
    <property name="dataSource" ref="dataSource" />

    <property name="jpaProperties">
        <props>
            <prop key="hibernate.show_sql">true</prop>
            <prop key="hibernate.hbm2ddl.auto">create</prop>
            <prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
        </props>
    </property>

    <property name="persistenceProvider">
        <bean class="org.hibernate.jpa.HibernatePersistenceProvider"></bean>
    </property>

</bean>

к

<bean id="entityManagerFactory"
    class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
    <property name="packagesToScan" value="org.wahid.cse.entity" />
    <property name="dataSource" ref="dataSource" />

    <property name="jpaProperties">
        <props>
            <prop key="hibernate.show_sql">true</prop>
            <prop key="hibernate.hbm2ddl.auto">create</prop>
            <prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
        </props>
    </property>

    <property name="persistenceProvider">
        <bean class="org.hibernate.jpa.HibernatePersistenceProvider"></bean>
    </property>

</bean>

У меня была эта проблема после миграции из spring-boot-starter-data-jpa веры. 1.5.7-2.0.2 (от старого спящего до спящего 5.2). В моем @Configuration класс я вводил entityManagerFactory а также 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;
}

Также не забудьте добавить зависимость hibernate-entitymanager в pom.xml, иначе EntityManagerFactory не будет найден в classpath:

<dependency>
        <groupId>org.hibernate</groupId>
        <artifactId>hibernate-entitymanager</artifactId>
        <version>5.0.12.Final</version>
</dependency>

Я думаю, что это связано с более новой версией весенней загрузки плюс использование JPA данных весны просто замените аннотацию @Bean над общедоступным LocalContainerEntityManagerFactoryBean entityManagerFactory() на @Bean(name="entityManagerFactory")

Определение имени боба должно решить проблему

Это может кому-нибудь помочь. Для меня ни одно из вышеперечисленных решений не сработало, поэтому я вошел в папку, в которой находится мой проект, удалил папку .idea, снова импортировал свой проект и запустил - mvn clean install.После этого все заработало. Я использую IntellJ.

Spring Data JPA по умолчанию ищет EntityManagerFactory с именем entityManagerFactory, Проверьте эту часть Javadoc EnableJpaRepositories или же Table 2.1 документации JPA Spring Data.

Это означает, что вы должны либо переименовать свой emf фасоль для entityManagerFactory или измените конфигурацию Spring на:

<jpa:repositories base-package="your.package" entity-manager-factory-ref="emf" />

(если вы используете XML)

или же

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

(если вы используете Java Config)
