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? I would like something like this:

@Component(firstName="joe", lastName="smith") @Component(firstName="mary", lastName="Williams") public class Person { /* blah blah */ }

It's not possible. You get a duplicate exception.

It's also far from optimal with configuration data like this in your implementation classes.

If you want to use annotations, you can configure your class with Java config:

@Configuration public class PersonConfig {      @Bean     public Person personOne() {         return new Person("Joe", "Smith");     }      @Bean     public Person personTwo() {         return new Person("Mary", "Williams");     } }
