Good day. I suffer three days already. Tell someone what the problem is.

The error gets out:

 org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [javax.persistence.EntityManagerFactory] is defined

    It's pretty obvious. In order to create a bin

     @Bean public PlatformTransactionManager transactionManager(EntityManagerFactory emf){ return new JpaTransactionManager(emf); }

    it must find a bin with an implementation of the EntityManagerFactory that you have not defined anywhere else. You should have something like this in AppConfig .

     @Bean public EntityManagerFactory entityManagerFactory(){ //здесь надо определить свой EntityManagerFactory }

    I suggest using EntityManagerFactory to createEntityManagerFactory BUT, you have plenty of problems besides that. As I understand it, you have the properties file, but its implementation is nowhere to be seen (there is no bundle of @PropertySource("путь_к_файлу_конфигурации") with @Autowired Environment environment )

    • Thank! I will try. - m_br0_89
