Bean Scope

The bean should be thread-safe in case concurrent threads is calling the bean at the same time.

When using prototype scope, then the bean will be looked up or created per call. However in case of lookup then this is delegated to the bean registry such as Spring or CDI (if in use), which depends on their configuration can act as either singleton or prototype scope. so when using prototype then this depends on the delegated registry. 使用Spring集成。
