java.lang.Object org.springframework.beans.factory.config.CommonsLogFactoryBean
Factory bean for commons-logging Log instances. Will expose the created Log object on getBean calls, and can be passed to bean properites of type org.apache.commons.logging.Log.
Useful for sharing Log instances among multiple beans instead of using one Log instance per class name, e.g. for common log topics.

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

public Class getObjectType()
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.

public boolean isSingleton()
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.
