Cannot resolve reference to bean 'entityManagerFactory' while setting constructor argument

Question

I just migrate to spring JPA technology and manage to change my simple jersey-hibernate project to spring JPA with custom crudrepository. But I can\'t deal with auto config

Answer 1

If you are using Hibernate, you have to provide most basic hibernate object (or bean in spring) called EntityManagerFactory to manage db sessions. This may be helpful : Obtaining EntityManager in Spring + Hibernate configuration

Answer 2

Exception says that there is no bean with name entityManagerFactory, Place a debug point in

public LocalContainerEntityManagerFactoryBean entityManagerFactory(
            EntityManagerFactoryBuilder factoryBuilder)

method org.springframework.boot.autoconfigure.orm.jpa.JpaBaseConfiguration.class and check why the bean is not getting initiated.

Oh, From discussion I came to the conclusion that mentioned issue is due to hibernate older dependencies. Also, the @Id which was imported needs to be from javax.persistence.id for all your entities.
