Spring: How to cleanly terminate prototype-scoped beans?

Question

According to Spring documentation when a bean is scoped as \"prototype\" spring does not manage the complete lifecycle of its objects. More specifically the destruction life

Answer 1

The only clean way to terminate prototype-scoped bean is to explicitly call some of its "destroy"-methods to dispose resources. You can also use Phantom References. Here is more info on different types of references.

Answer 2

What you're looking for is the DestructionAwareBeanPostProcessor, it's a sub-interface of BeanPostProcessor.

You could create a new implementation of that interface yourself, or use one of its implementing classes, like CommonAnnotationBeanProcessor.
