BeanDefinitionRegistry
Registers a new singleton bean at runtime. This method expects that the bean definition data will have been compiled ahead of time.
If bean definition data is found the method will perform dependency injection on the instance followed by
invoking any PostConstruct
hooks.
If no bean definition data is found the bean is registered as is.

public boolean containsProperty(String name)
PropertyResolver
Whether the given property is contained within this resolver.
Note that this method will return false for nested properties. In other words given a key of foo.bar this method will
return false for: resolver.containsProperty("foo")
To check for nested properties using PropertyResolver.containsProperties(String)
instead.
