    • registerBeanConfiguration

      default BeanDefinitionRegistry registerBeanConfiguration(BeanConfiguration configuration)
      Registers a bean configuration. This allows disabling a set of beans based on a condition.
      Parameters:
      configuration - The configuration
      Returns:
      The registry
      Since:
      4.8.0

    • registerBeanDefinition

      default <B> BeanDefinitionRegistry registerBeanDefinition(RuntimeBeanDefinition<B> definition)
      Registers a new reference at runtime. Not that registering beans can impact the object graph therefore should this should be done as soon as possible prior to the creation of other beans preferably with a high priority Context scope bean.

      <T> BeanDefinitionRegistry registerSingleton(Class<T> type, T singleton, @Nullable Qualifier<T> qualifier, boolean inject)

      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.
