Method Summary

Modifier and Type	Method	Description
static <B, A extends Annotation> List<B>	getBeansWithAnnotation(org.springframework.context.ApplicationContext applicationContext, Class<B> beanType, Class<A> annotationType)	Find all beans which are annotated with the supplied Annotation type.
static <B, A extends Annotation> LinkedHashMap<B,A>	getOrderedBeansWithAnnotation(org.springframework.context.ApplicationContext applicationContext, Class<B> beanType, Class<A> annotationType)	Find all beans of the given type which may be annotated with the supplied Annotation type and returns a map of matching bean instances with the annotation instance (or null if the bean is not annotated with the specified annotation type).
static void	sortBeansIncludingOrderAnnotation(org.springframework.context.ApplicationContext applicationContext, Class<?> beanType, List<?> beans)	Sorts the supplied list in place using an OrderComparator that takes the @Order annotation on bean factory methods in configuration classes into account.

Method Details

getOrderedBeansWithAnnotation

public static <B, A extends Annotation>
LinkedHashMap<B,A> getOrderedBeansWithAnnotation(org.springframework.context.ApplicationContext applicationContext,
 Class<B> beanType,
 Class<A> annotationType)

Find all beans of the given type which may be annotated with the supplied Annotation type and returns a map of matching bean instances with the annotation instance (or null if the bean is not annotated with the specified annotation type).

Note that the map is ordered according to the matching beans Order annotation.

Note that this method considers objects created by FactoryBeans, which means that FactoryBeans will get initialized in order to determine their object type.

Type Parameters:

B - type of bean

A - type of annotation

Parameters:

applicationContext - the application context

beanType - the type of bean

annotationType - the type of annotation

Returns:

a map of matching bean instances with the annotation instance (or null) ordered according to their Order with annotation

getBeansWithAnnotation

public static <B, A extends Annotation> List<B> getBeansWithAnnotation(org.springframework.context.ApplicationContext applicationContext,
 Class<B> beanType,
 Class<A> annotationType)

Find all beans which are annotated with the supplied Annotation type.

Note that this method considers objects created by FactoryBeans, which means that FactoryBeans will get initialized in order to determine their object type.

Type Parameters:

B - type of bean

A - type of annotation

Parameters:

applicationContext - the application context

beanType - the type of bean

annotationType - the type of annotation

Returns:

a list of the matching beans ordered according to their Order annotation

sortBeansIncludingOrderAnnotation

public static void sortBeansIncludingOrderAnnotation(org.springframework.context.ApplicationContext applicationContext,
 Class<?> beanType,
 List<?> beans)

Sorts the supplied list in place using an OrderComparator that takes the @Order annotation on bean factory methods in configuration classes into account.

Parameters:

applicationContext - the application context

beanType - the type of beans in the list

beans - the list of beans to sort
