Spring 3 @Component and static factory method

If I'm writing a static factory method to create objects, how do I use the '@Component' annotation for that factory class and indicate (with some annotation) the static factory method which should be called to create beans of that class? Following is the pseudo-code of what I mean:

@Component
class MyStaticFactory
{
    @<some-annotation>
    public static MyObject getObject()
    {
        // code to create/return the instance
    }
}
Solution

  • I am afraid you can't do this currently. However it is pretty simple with Java Configuration:

    @Configuration
public class Conf {

    @Bean
    public MyObject myObject() {
        return MyStaticFactory.getObject()
    }

}

    In this case MyStaticFactory does not require any Spring annotations. And of course you can use good ol' XML instead.
