I would guess that this is due to a change in Spring Framework but it is hard to be certain without some more information. You could try overriding the version of Spring Framework to see if the problem occurs with Spring Boot 3.2.5 and Spring Framework 6.1.10. If that does not help to narrow down the cause and you would like us to spend some more time investigating, please spend some time providing a complete yet minimal sample that reproduces the problem. You can share it with us by pushing it to a separate repository on GitHub or by zipping it up and attaching it to this issue.

Hey wilkinsona,

Thanks for the immediate response. It seems that the change was introduced with org.springframework:spring-context version 6.1.7. My guesses are:

spring-context/src/main/java/org/springframework/context/support/AbstractApplicationContext.java

and

spring-context/src/main/java/org/springframework/context/support/GenericApplicationContext.java

When I set the Spring Boot version to 3.3.1 and spring-context to 6.1.6, all tests are passing.
I will try to recreate the issue in a small sample project, or do you think it will be a better idea to report the issue to the spring-core team?

Thanks, @emomast. Given that it works when you change the Spring Framework version, we'll transfer this to the Framework team so that they can investigate. A small sample project will help them to do that so please do create one.

This seems to be a side effect of #32470 in 6.1.7 - any idea why the EntityManagerFactory bean is null here? We can specifically check for that and ignore it accordingly, just wondering why we run into such a situation.

No. It's a strange bean to have been defined at all in a WebFlux application, particularly when using the @WebFluxTest slice. The requested sample may help us to understand how things have ended up as they apparently have.

We are going to leniently ignore any such type mismatch for LoadTimeWeaverAware beans as of 6.1.11 in order to address that kind of regression in 6.1.7, simply catching BeanNotOfRequiredTypeException and logging it. Before #32470, we called plain getBean(name) without any type specified and ignored the result, so such a type mismatch would not have raised a flag.

That said, it's still worth clarifying why an EntityManagerFactory bean is defined there but then apparently returning null from its factory method? Nulling out beans that way is not good practice anymore since Spring Framework 5.0, this should rather not get registered at all (e.g. conditionally deactivated at the bean definition level).

Looking at Boot's auto-configured entityManagerFactory bean, it can never return null from the @Bean method. In the absence of any evidence to the contrary, I would guess that this is a user-defined bean that returns null in some circumstances.

@wilkinsona @jhoeller Thanks for taking the time to look into this issue. We are using hibernate-reactive as a provider and have the following configurations:

@Bean
  public Stage.SessionFactory sessionFactory(final EntityManagerFactory entityManagerFactory) {
    return entityManagerFactory.unwrap(Stage.SessionFactory.class);
  }

  @Bean
  public LocalContainerEntityManagerFactoryBean entityManagerFactory() {
    final LocalContainerEntityManagerFactoryBean em = new LocalContainerEntityManagerFactoryBean();
    em.setDataSource(dataSource());
    em.setJpaVendorAdapter(new HibernateJpaVendorAdapter());
    em.setJpaProperties(additionalProperties());
    em.setPersistenceProvider(new ReactivePersistenceProvider());
    em.setPackagesToScan(
        ...
    );
    return em;
  }

In the test configuration we are mocking the EntityManager:

  @MockBean
  EntityManager entityManager;

And in the controller tests we are mocking all services and repositories. I assumed that annotating a test with WebFluxTest will skip the whole persistence configuration, so this is way I was confused why it tries to initialise an EntityManagerFactory

Probably adding a conditional loading of the Bean only when the application is running will solve the issue?

The method that raises this issue is:

  @Bean
  public LocalContainerEntityManagerFactoryBean entityManagerFactory() {
    final LocalContainerEntityManagerFactoryBean em = new LocalContainerEntityManagerFactoryBean();
    return em;
  }

You could try to watch your startup in the debugger, seeing what actually happens when your entityManagerFactory bean is being initialized by the LoadTimeWeaverAware step in AbstractApplicationContext. According to the stacktrace, it ends up up returning null for that bean which indicates that the actually used factory method returned null there, or possibly a custom BeanPostProcessor turned it to null? It is clearly not just calling the @Bean method that you have shown above.

If you intentionally return null from some factory method under certain circumstances, you are better off applying a condition to your bean definition so that it never gets registered when not needed. However, it seems something else is nulling out your bean there, so I'm not sure that recipe applies.

FWIW, the latest 6.1.11 snapshot should address this issue already, leniently ignoring such a null bean - which is worth testing in its own right, even if a proper solution is to avoid the null bean there to begin with.

As a side note: Declaring the return type of your @Bean entityManagerFactory() method as FactoryBean<EntityManagerFactory> could also avoid the issue here since that type does not indicate a LoadTimeWeaverAware bean to begin with, never running into that early initialization attempt.

Generally, the recommendation is to make the factory method return type as specific as possible though, so LocalContainerEntityManagerFactoryBean is fine from that perspective.

This is the debug log when starting a test:

I added the conditional loading, so the bean is not loaded during tests anymore
