Method Summary

<A extends Annotation> A	findAnnotationOnBean(String beanName, Class<A> annotationType) Find a Annotation of annotationType on the specified bean, traversing its interfaces and super classes if no annotation can be found on the given class itself, as well as checking its raw bean class if not found on the exposed bean reference (e.g. in case of a proxy).
<T> T	getBean(String name)
<T> T	getBean(String name, Class<T> requiredType)
ListableBeanFactory	getBeanFactory() Return the wrapped ListableBeanFactory.
<T> Map<String,T>	getBeansOfType(Class<T> type)
<T> Map<String,T>	getBeansOfType(Class<T> type, boolean includeNonSingletons, boolean allowEagerInit)
Map<String,Object>	getBeansWithAnnotation(Class<? extends Annotation> annotationType) Find all beans whose Class has the supplied Annotation type.
