Spring / Spring Beans

Spring bean: difference between stateless and stateful beans.

stateless beans: beans that are singleton and are initialized only once. The only state they have is a shared state. These beans are created while the ApplicationContext is being initialized. The SAME bean instance will be returned/injected during the lifetime of this ApplicationContext. .

stateful beans: beans that can carry state (instance variables). These are created every time an object is required.
