Examples of org.springframework.beans.factory.BeanFactory.containsBean()

org.springframework.beans.factory.BeanFactory.containsBean()
Does this bean factory contain a bean definition or externally registered singleton instance with the given name?
If the given name is an alias, it will be translated back to the corresponding canonical bean name.
If this factory is hierarchical, will ask any parent factory if the bean cannot be found in this factory instance.
If a bean definition or singleton instance matching the given name is found, this method will return {@code true} whether the named bean definition is concreteor abstract, lazy or eager, in scope or not. Therefore, note that a {@code true}return value from this method does not necessarily indicate that {@link #getBean}will be able to obtain an instance for the same name. @param name the name of the bean to query @return whether a bean with the given name is present
