    • 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.

      Type Parameters:
      T - The concrete type
      Parameters:
      type - The bean type
      singleton - The singleton bean
