"prototype" (independent instance resulting from each call to getBean).
Default is "singleton".
By default, a bean will be a singleton, unless the bean has a parent
bean definition in which case it will inherit the parent's scope.
Singletons are most commonly used, and are ideal for multi-threaded
service objects. Further scopes, such as "request" or "session", might
be supported by extended bean factories (e.g. in a web environment).
Note: This attribute will not be inherited by child bean definitions.
Hence, it needs to be specified per concrete bean definition.
Inner bean definitions inherit the singleton status of their containing
bean definition, unless explicitly specified: The inner bean will be a
singleton if the containing bean is a singleton, and a prototype if
