java.lang.Object org.springframework.beans.factory.support.SimpleInstantiationStrategy
public class SimpleInstantiationStrategy
Simple object instantiation strategy for use in a BeanFactory.
Does not support Method Injection, although it provides hooks for subclasses to override to add Method Injection support, for example by overriding methods.

if none.
Allows factory method implementations to determine whether the current caller is the container itself as opposed to user code.
