Spring and factory object

I have an abstract class with a static method that returns either one concrete subclass

or another, depending on this static method's arguments.

How do I define a bean in spring configuration f开发者_开发技巧ile that will invoke this static method with the arguments?

From the Spring documentation, you just treat the parameters as constructor arguments:

<bean id="exampleBean" class="examples.ExampleBean" factory-method="createInstance">
  <constructor-arg ref="anotherExampleBean"/>
  <constructor-arg ref="yetAnotherBean"/>
  <constructor-arg value="1"/> 
</bean>

See sections 3.2.3.2.2 and 3.2.3.2.3 - I think that might be what you're looking for.
