Creating bean using static method from another class

Question

I have a factory class which has various static methods to return the instances of some classes. How can a bean be created in spring using static factory method in different class?

something like:

public class InstanceFactory
{    
  public static JellyBean getJellyBeanInstance()
  {
    return new JellyBean(); 
  }
}

I need a JellyBean.

Add example of your code

Just change your getJellyBeanInstance() method to non-static, then you need:

<bean id="instanceFactory" class="InstanceFactory"/>

<bean id="yourBeanId" factory-bean="instanceFactory" factory-method="getJellyBeanInstance"/>

class="YourFactoryClass" shouldnt this be the name of the class whose instance needs to be created?

@varun you're right, that works if the static factory method is on the class itself, I'll update the answer.

what if static factory method is not on the class itself, its inside some other class

I really dont want my factory to be a bean itself.

This should help: Spring Bean Instantiation with a static factory method

For instance factory method, next section from the document should help.

I already know how it can be done if I create bean of my factory class, but i dont want to create any instance of my factory class. Lets say my factory class is abstract.
