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.

still no answer to this question? – supertonsky Jan 08 '16 at 06:04 — supertonsky, Jan 08 '16 at 06:04

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 Dec 10 '13 at 09:46
@varun you're right, that works if the static factory method is on the class itself, I'll update the answer. – MattR Dec 10 '13 at 09:59

what if static factory method is not on the class itself, its inside some other class – varun Dec 10 '13 at 10:01
I really dont want my factory to be a bean itself. – varun Dec 10 '13 at 11:50

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. – varun Dec 10 '13 at 11:53
