Method Detail

beansWithAnnotationIncludingAncestors

public static Map<String,Object> beansWithAnnotationIncludingAncestors(org.springframework.context.ApplicationContext ctx,
                                                                             Class<? extends Annotation> annotationType)
                                                                      throws org.springframework.beans.BeansException

Returns all beans annotated with the specified annotation type defined in the specified application context and all its ancestor contexts.

If both a descendant and an ancestor context contain a bean with the same id and both are annotated with the specified annotation type, the bean in the descendant context takes precedence.

Parameters:

ctx - the starting application context

annotationType - the annotation type to search for

Returns:

a map with bean ids and beans

Throws:

org.springframework.beans.BeansException - if a bean could not be created

getNonScopedTargetBeansWithAnnotation

public static Map<String,Object> getNonScopedTargetBeansWithAnnotation(org.springframework.context.ApplicationContext ctx,
                                                                             Class<? extends Annotation> annotationType)

Helper method to find all non scoped target beans whose Class has the supplied Annotation type, returning a Map of bean names with corresponding bean instances.

ListableBeanFactory.getBeans* methods are able to look up any beans, even both the proxy and the target variant of a scoped bean. The advised workaround is either check getBeanDefinition(candidateName).isAutowireCandidate() and skip non-autowire beans that way or simply check for beanName.startsWith(ScopedProxyUtils.TARGET_NAME_PREFIX) (which is a supported way of detecting generated scoped target beans).

• https://jira.spring.io/browse/SPR-14887

Parameters:

ctx - the application context to get the annotated beans from

annotationType - the type of annotation to look for

Returns:

a Map with the matching beans, containing the bean names as keys and the corresponding bean instances as values
