Access the injectee component from bean factory

Multi tool use
Suppose we have a prototype-scoped bean.
public class FooConfiguration {
@Bean
@Scope("prototype")
public Foo foo(@Autowired Bar bar) {
return new Foo(bar);
}
}
We're injecting this bean to a class, TheDependent
.
@Component
public class TheDependent {
@Autowired
private Foo foo;
}
But there is also another one.
@Component
public class AnotherOne {
@Autowired
private Foo foo;
}
In each @Autowired
, a new instance of Foo
gets created because it's annotated with @Scope("prototype")
.
I would like to access the 'dependent' class from the factory method, FooConfiguration#foo(Bar)
. Is it possible? Can Spring inject me some sort of context object to the parameters of the factory method, providing information about the point of injection?

Yes. You can inject DefaultListableBeanFactory
which is the spring bean container containing all the bean informations to the parameters of the bean factory method :
@Bean
@Scope("prototype")
public Foo foo(@Autowired Bar bar , DefaultListableBeanFactory beanFactory) {
//Get all the name of the dependent bean of this bean
for(String dependentBean : beanFactory.getDependentBeans("foo")){
//Get the class of each dependent bean
beanFactory.getType(dependentBean);
}
return new Foo(bar);
}
That was what I was asking for. Spot on!
