<p style='margin-top:0;margin-bottom:10px;'>Sometimes we want to fit a parametrized injection point with your exact bean. The most common case is when you trying to inject a Class<>.</p>
<p style='margin-top:0;margin-bottom:10px;'>Let's see:</p>
<p style='margin-top:0;margin-bottom:10px;'>class Animal {</p>
<p style='margin-top:0;margin-bottom:10px;'>}</p>
<p style='margin-top:0;margin-bottom:10px;'>class Dog extends Animal {</p>
<p style='margin-top:0;margin-bottom:10px;'>}</p>
<p style='margin-top:0;margin-bottom:10px;'>class PitBull extends Dog {</p>
<p style='margin-top:0;margin-bottom:10px;'>}</p>
<p style='margin-top:0;margin-bottom:10px;'>class ShowClassName<T> {</p>
<p style='margin-top:0;margin-bottom:10px;'> @Inject<br/>
public ShowClassName(Class<T> clazz) </p>
{
System.out.println(clazz.getName());
}<br/>
<br/>
}<br/>
<br/>
public class ExactlyTestCase {<br/>
<br/>
@Inject<br/>
private ShowClassName<Animal> animalShowClassName;<br/>
<br/>
@Inject<br/>
private ShowClassName<Dog> dogShowClassName;<br/>
<br/>
@Inject<br/>
private ShowClassName<PitBull> pitBullShowClassName;<br/>
<br/>
@Produces<br/>
public Class<Animal> createAnimalClass() {
return Animal.class;
}<br/>
<br/>
@Produces<br/>
public Class<Dog> createDogClass() {
return Dog.class;
}<br/>
<br/>
@Produces<br/>
public Class<PitBull> createPitBullClass() {
return PitBull.class;
}<br/>
<br/>
}<br/>
<br/>
Class<PitBull> fit with 3 and Class<Dog> fit with 2. I know this behavior is frequently expected but in some cases it's not, as I showed you. In theses cases use qualifiers does not help because i must have one qualifier for each Class and have one ShowClassName Bean for each Class with its especific qualifier annotated, wich does not provide reuse.<br/>
<br/>
Have this will be very nice:<br/>
<br/>
class ShowClassName<T> {<br/>
<br/>
@Inject<br/>
public ShowClassName(@Exactly Class<T> clazz) {
System.out.println(clazz.getName());
}
<p style='margin-top:0;margin-bottom:10px;'>}</p>
<p style='margin-top:0;margin-bottom:10px;'>Thanks</p>
