Instantiating multiple beans of the same class with Spring annotations

Question

With an XML configured Spring bean factory, I can easily instantiate multiple instances of the same class with different parameters. How can I do the same with annotations?

Answer 1

I just had to solve a similar case. This may work if you can redefine the class.

// This is not a @Component
public class Person {

}

@Component
public PersonOne extends Person {
   public PersonOne() {
       super("Joe", "Smith");
   }
}

@Component
public PersonTwo extends Person {
   public PersonTwo() {
    super("Mary","Williams");
   }
}

Then just use PersonOne or PersonTwo whenever you need to autowire a specific instance, everywhere else just use Person.
