[FIXED] Get a bean (programmatically registered) from Spring context?

Issue

I registered a bean programmatically:

@Autowired
private GenericApplicationContext applicationContext;

[...]

applicationContext.registerBean("a0", A.class, () -> new A(0));

// make sure to set up the bean
applicationContext.getBean("a0");

When I want to get this bean by name, it works and always returns the same instance:

applicationContext.getBean("a0");

But when I want to get all beans of type A.class, it returns en empty Map:

Map<String, A> as = applicationContext.getBeansOfType(A.class);

as = [] !!!

I'm working with Spring 5.0, Why does Spring consider have no bean of type A in my context while I can retrieve them by name ?

Solution

Use instead BeanFactoryUtils.beansOfTypeIncludingAncestors:

BeanFactoryUtils.beansOfTypeIncludingAncestors(applicationContext, A.class)

See Spring forum answer:

Does not consider any hierarchy this factory may participate in. Use BeanFactoryUtils' beansOfTypeIncludingAncestors to include beans in ancestor factories too.
