a single bean definition to a single object instance per Spring IoC container.
To put it another way, when
you define a bean definition and it is scoped as a singleton, the Spring IoC container creates exactly one instance
of the object defined by that bean definition. This single instance is stored in a cache of such singleton beans, and all
subsequent requests and references for that named bean return the cached object.
