registerSingleton
@NonNull public <T> @NonNull ApplicationContext registerSingleton(@NonNull @NonNull Class<T> type, @NonNull T singleton, @Nullable @Nullable Qualifier<T> qualifier, boolean inject) Description copied from interface: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.

Description copied from interface:PropertyResolver
Whether the given property is contained within this resolver.

this method will returnfalse
for:resolver.containsProperty("foo")
To check for nested properties using
PropertyResolver.containsProperties(String)
instead.- Specified by:

- The name of the property- Returns:
- True if it is
-

T
- The concrete type- Parameters:
name
- The nameconversionContext
- The conversion context- Returns:
- An optional containing the property value if it exists
