java.lang.Object org.springframework.beans.factory.config.ResourceFactoryBean
FactoryBean for Resource descriptors. Exposes a looked-up Resource object.
Delegates to the ApplicationContext's getResource method. Resource loading behavior is specific to the context implementation.

FactoryBean
If this method returns null, the factory will consider the FactoryBean as not fully initialized and throw a corresponding FactoryBeanNotInitializedException.

FactoryBean
For a singleton, this should try to avoid singleton creation as far as possible; it should rather estimate the type in advance. For prototypes, returning a meaningful type here is advisable too.
This method can be called before this FactoryBean has been fully initialized. It must not rely on state created during initialization; of course, it can still use such state if available.
NOTE: Autowiring will simply ignore FactoryBeans that return null here. Therefore it is highly recommended to implement this method properly, using the current state of the FactoryBean.

FactoryBean
The singleton status of the FactoryBean itself will generally be provided by the owning BeanFactory; usually, it has to be defined as singleton there.
