I'm developing application using spring data jpa,hibernate,mysql,tomcat7,maven and it's create error.I'm trying to figure it out but i failed.

error are Cannot resolve reference to bean 'entityManagerFactory' while setting constructor argument; No bean named 'entityManagerFactory' is defined; Injection of autowired dependencies failed

RoleRepository is

import org.springframework.data.jpa.repository.JpaRepository;
import org.wahid.cse.entity.Role;

 public interface RoleRepository extends JpaRepository<Role, Integer>{

 }

回答1:

Spring Data JPA by default looks for an EntityManagerFactory named entityManagerFactory. Check out this part of the Javadoc of EnableJpaRepositories or Table 2.1 of the Spring Data JPA documentation.

That means that you either have to rename your emf bean to entityManagerFactory or change your Spring configuration to:

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

(if you are using XML)

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

(if you are using Java Config)

回答2:

In your application context, change the bean with id from emf to 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>

<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>

Had this issue when migrated spring boot 1.5.2 to 2.0.4. Instead of creating bean I've used @EnableAutoConfiguration in the main class and it solved my problem.

回答4:

I had this issue after migrating from spring-boot-starter-data-jpa ver. 1.5.7 to 2.0.2 (from old hibernate to hibernate 5.2). In my @Configuration class I injected entityManagerFactory and 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;
}

Also remember to add hibernate-entitymanager dependency to pom.xml otherwise EntityManagerFactory won't be found on classpath:

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

回答5:

I think this is related to the newer version of spring boot plus using spring data JPA just replace @Bean annotation above public LocalContainerEntityManagerFactoryBean entityManagerFactory() to @Bean(name="entityManagerFactory")

Determining the name of bean should solve the issue

回答6:

I had the same problem and got it resolved by deleting .m2 maven repo (C:\Users\user\ .m2)

回答7:

In my specific case I seemed to have been missing the dependency

 <!-- https://mvnrepository.com/artifact/org.springframework/spring-jdbc -->
 <dependency>
   <groupId>org.springframework</groupId>
   <artifactId>spring-jdbc</artifactId>
   <version>5.1.3.RELEASE</version>
 </dependency>

回答8:

just updated the springboot version to 2.1.3 and it worked of me
