      Obtains a provider for the specified type allowing for lazy on-demand retrieval of instances
      Type Parameters:
      T - the type of the returned instance
      Parameters:
      cls - the bean's class to instantiate
      Returns:

    • getJust

      public <T> T getJust(Class<T> cls)
      Create a new instance of the exacted passed bean's class, resolving the injection points.
      Type Parameters:
      T - the type of the returned instance
      Parameters:
      cls - the bean's class to instantiate
      Returns:
      the new class instance with the injection point resolved
      Throws:
      org.springframework.beans.factory.NoSuchBeanDefinitionException - if no bean of the given type was found
      org.springframework.beans.factory.NoUniqueBeanDefinitionException - if more than one bean of the given type was found

    • selectJust

      public <T> Optional<T> selectJust(Class<T> cls)
      Selects a bean instance of the exact class type (not subclasses). For singleton beans, instances are cached for performance. For prototype/request/session/company scoped beans, only metadata is cached.
      Type Parameters:
      T - the type of the returned instance
      Parameters:
      cls - the exact bean's class to find
      Returns:
      an Optional containing the bean instance if found, empty otherwise
