required a bean of type 'org.springframework.boot.orm.jpa.EntityManagerFactoryBuilder' that could not be found

I have a spring boot 2.4.0 application that connects to 2 different data sources. I keep getting this error. I searched for solutions all over internet. I found that I need to specify only one of my beans with @Primary, fact that I also did (so it was not my case). I will post the error and classes below. Thank you:

Description:

Parameter 0 of method entityManagerFactory in demo.Db1Config required a bean of type 'org.springframework.boot.orm.jpa.EntityManagerFactoryBuilder' that could not be found.


Action:

Consider defining a bean of type 'org.springframework.boot.orm.jpa.EntityManagerFactoryBuilder' in your configuration.>

Solution

  • I see issue in Application.java, because you have excluded HibernateJpaAutoConfiguration.class, that auto configurer has link on JpaBaseConfiguration class in which EntityManagerFactoryBuilder creates. enter image description here After that you have two options for solving issue:

    @Bean
public EntityManagerFactoryBuilder entityManagerFactoryBuilder() {
   return new EntityManagerFactoryBuilder(new HibernateJpaVendorAdapter(), new HashMap<>(), null);
}

    P.S. I am not sure if you need following code in configs in total:

    @EnableAutoConfiguration(exclude={DataSourceAutoConfiguration.class})
