[Springframework-developer] autowire by type on a factory-bean factory-method

[Keith D. <ke...@in...>]

Autowire by type on a factory-bean factory-method doesn't seem supported.  I
noticed this in a dependency injection-enabled spring test, where I wanted
to auto-inject the result of a factory method.  Would this be difficult to
do?

I understand that getType on any factory-method type bean returns Null,=20
implying that autowire by type wouldn't work with one of these. Getting=20
the getType to check the type of the bean returned by factory-method is=20
not that difficult (just a bit of introspection), but isn't (as I=20
understand it) underway at present.

As per my latest comment on your other issue, this will work now for =
beans
with factory method as well, provided that they are defined as =
singleton:

Once a bean with a factory method has been instantiated, its type _is_ =
known
and correctly detected by "getType", "getBeanNamesOfType" and
"getBeansOfType".=20

I've just further refined AbstractBeanFactory to actually trigger
instantiation of a bean with a factory method even when just determining =
the
type - provided that the target bean is a singleton. The BeanFactory =
already
behaves similarly for beans that implement the FactoryBean interface.

For prototype beans with factory method declaration, the type will still =
be
considered undeterminable, which I think is acceptable.
