FactoryBean's isSingleton()

[Arya Pramod]

Hi Everybody,

By returning true from isSingleton() method of FactoryBean implementation class,

Does Spring create a Singleton instance of the Class Implementing the FactoryBean Interface


If yes, then the following code

    
public class FCImpl implements FactoryBean {
....
 
<bean id="FCImpl" class="com.test.FCImpl" scope="prototype"/>

does not throw an exception even when the Implementing class has explicitly defined itself as a singleton through scope="prototype" and isSingleton() method returns true.

Thanks In Advance,
Pramod

Returning true in isSingleton() will not magically make your bean a singleton. You have to make it work like a singleton, so you have to make sure that getObject() always returns the same object (a reference that can be cached). Is there any special reason why you are using this interface ?

Thank You Christophe,

I am actually new to Spring Framework, so just getting some hands-on knowledge.
