Javadoc

Check if this bean factory contains a singleton instance with the given name. Only checks already instantiated singletons; does not return true for singleton bean definitions that have not been instantiated yet.

The main purpose of this method is to check manually registered singletons (see registerSingleton). Can also be used to check whether a singleton defined by a bean definition has already been created.

To check whether a bean factory contains a bean definition with a given name, use ListableBeanFactory's containsBeanDefinition. Calling both containsBeanDefinition and containsSingleton answers whether a specific bean factory contains an own bean with the given name.

Use BeanFactory's containsBean for general checks whether the factory knows about a bean with a given name (whether manually registed singleton instance or created by bean definition), also checking ancestor factories.
