If you want to @Autowire a bean of type A into a bean of type B, Spring must manage the lifecycle of both beans. If you manually create bean A using "new()", Spring has now way to manage that bean instance and hence no way to auto-wire it.

If the instantiation of bean A is complex, you can use a Spring factory bean to manage it. There is a good explanation of factory beans here: http://blog.springsource.org/2011/08/09/whats-a-factorybean/
