I was amazed to find this because I was trying to write exactly the same thing but was having a 20 minute battle with the reflection API and the generics interface. Your solution was spot on :-) and I was able to drop in your extractTypeParameter() method over the top of mine. great! it really makes it just "that" much bit tidier. Hi Rob,

You can inject MyQueue into a MyQueue<String> property. Rob That should have been:

Francesco,

There is no need to create that bean definition - you can simply use MyQueue without the type parameter - at runtime there is no such type as MyQueue<String> when looking at an object instance. You can inject MyQueue into a MyQueue<String> property.

a question about generics and Spring:
is this kind of bean definition supported in Spring 2.0?

<bean id="test" class="MyQueue<String>" />

I mean, I created a generic bean class MyQueue<T> and I want to specify the type "String" when creating a bean in Spring configuration

Thanks a lot
Francesco

That's great news. I meant to ask if maybe Spring 2.0 did this, but didn't. We are still on 1.2.5 in our installation, but this is one more reason for me to consider moving to 2.0 sooner than later.
