public boolean containsBean(String name) Implements org.springframework.beans.factory.BeanFactory.containsBean. Doc from org.springframework.beans.factory.BeanFactory.containsBean. Does this bean factory contain a bean definition or externally registered singleton instance with the given name? If the given name is an alias, it will be translated back to the corresponding canonical bean name. If this factory is hierarchical, will ask any parent factory if the bean cannot be found in this factory instance. If a bean definition or singleton instance matching the given name is found, this method will return `true` whether the named bean definition is concrete or abstract, lazy or eager, in scope or not. Therefore, note that a `true` return value from this method does not necessarily indicate that `getBean` will be able to obtain an instance for the same name.

If the given name is an alias, it will be translated back to the corresponding canonical bean name.

If this factory is hierarchical, will ask any parent factory if the bean cannot be found in this factory instance.

If a bean definition or singleton instance matching the given name is found, this method will return true whether the named bean definition is concrete or abstract, lazy or eager, in scope or not.

Note that the return value will never be `null`.

Doc from org.springframework.beans.factory.BeanFactory.getBeanProvider. Return a provider for the specified bean, allowing for lazy on-demand retrieval of instances, including availability and uniqueness options. This variant allows for specifying a generic type to match, similar to reflective injection points with generic type declarations in method/constructor parameters. Note that collections of beans are not supported here, in contrast to reflective injection points. For programmatically retrieving a list of beans matching a specific type, specify the actual bean type as an argument here and subsequently use `ObjectProvider#orderedStream()` or its lazy streaming/iteration options. Also, generics matching is strict here, as per the Java assignment rules. For lenient fallback matching with unchecked semantics (similar to the ´unchecked´ Java compiler warning), consider calling `getBeanProvider(Class)` with the raw type as a second step if no full generic match is `available` with this variant.
