BeanFactoryUtils

<init>

Convenience methods operating on bean factories, in particular on the ListableBeanFactory interface.

Returns bean counts, bean names or bean instances, taking into account the nesting hierarchy of a bean factory (which the methods defined on the ListableBeanFactory interface don't, in contrast to the methods defined on the BeanFactory interface).

GENERATED_BEAN_NAME_SEPARATOR

Separator for generated bean names. If a class name or parent name is not unique, "#1", "#2" etc will be appended, until the name becomes unique.

beanNamesForAnnotationIncludingAncestors

Get all bean names whose Class has the supplied Annotation type, including those defined in ancestor factories, without creating any bean instances yet. Will return unique names in case of overridden bean definitions.

beanNamesForTypeIncludingAncestors

Get all bean names for the given type, including those defined in ancestor factories. Will return unique names in case of overridden bean definitions.

Does consider objects created by FactoryBeans, which means that FactoryBeans will get initialized. If the object created by the FactoryBean doesn't match, the raw FactoryBean itself will be matched against the type.

This version of beanNamesForTypeIncludingAncestors automatically includes prototypes and FactoryBeans.

Get all bean names for the given type, including those defined in ancestor factories. Will return unique names in case of overridden bean definitions.

Does consider objects created by FactoryBeans if the "allowEagerInit" flag is set, which means that FactoryBeans will get initialized. If the object created by the FactoryBean doesn't match, the raw FactoryBean itself will be matched against the type. If "allowEagerInit" is not set, only raw FactoryBeans will be checked (which doesn't require initialization of each FactoryBean).

beanNamesIncludingAncestors

Return all bean names in the factory, including ancestor factories.

beanOfType

Return a single bean of the given type or subtypes, not looking in ancestor factories. Useful convenience method when we expect a single bean and don't care about the bean name.

Does consider objects created by FactoryBeans, which means that FactoryBeans will get initialized. If the object created by the FactoryBean doesn't match, the raw FactoryBean itself will be matched against the type.

If "allowEagerInit" is not set, only raw FactoryBeans will be checked (which doesn't require initialization of each FactoryBean).

beanOfTypeIncludingAncestors

Return a single bean of the given type or subtypes, also picking up beans defined in ancestor bean factories if the current bean factory is a HierarchicalBeanFactory. Useful convenience method when we expect a single bean and don't care about the bean name.

Does consider objects created by FactoryBeans, which means that FactoryBeans will get initialized. If the object created by the FactoryBean doesn't match, the raw FactoryBean itself will be matched against the type.

Note: Beans of the same name will take precedence at the 'lowest' factory level, i.e. such beans will be returned from the lowest factory that they are being found in, hiding corresponding beans in ancestor factories. This feature allows for 'replacing' beans by explicitly choosing the same bean name in a child factory; the bean in the ancestor factory won't be visible then, not even for by-type lookups.

countBeansIncludingAncestors

Count all beans in any hierarchy in which this factory participates. Includes counts of ancestor bean factories.

Beans that are "overridden" (specified in a descendant factory with the same name) are only counted once.

isFactoryDereference

Return whether the given name is a factory dereference (beginning with the factory dereference prefix).

isGeneratedBeanName

Return whether the given name is a bean name which has been generated by the default naming strategy (containing a "#..." part).

originalBeanName

Extract the "raw" bean name from the given (potentially generated) bean name, excluding any "#..." suffixes which might have been added for uniqueness.

transformedBeanName

Return the actual bean name, stripping out the factory dereference prefix (if any, also stripping repeated factory prefixes if found).
