I am reading spring through its official documentation and at one place I came to a line that uses prototype scope for all stateful beans while singleton for stateless beans.
I know there is something as stateful as well as stateless beans in EJB but this is not what they have mentioned in the documents.
Can anyone explain to me what exactly this means of stateful as well stateless beans in Spring
Thanks in advance
From spring perspective
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
ApplicationContextis being initialized. The SAME bean instance will be returned/injected during the lifetime of thisApplicationContext.stateful beans: beans that can carry state (instance variables). These are created EVERY time an object is required (like using the “new” operator in java).
These are not EJB statfull/stateless session beans.
