Class AnnotationBeanNameGenerator
- java.lang.Object
- org.springframework.context.annotation.AnnotationBeanNameGenerator
- All Implemented Interfaces:
BeanNameGenerator
public class AnnotationBeanNameGenerator extends Object implements BeanNameGenerator
BeanNameGenerator
implementation for bean classes annotated with the@Component
annotation or with another annotation that is itself annotated with@Component
as a meta-annotation. For example, Spring's stereotype annotations (such as@Repository
) are themselves annotated with@Component
.Also supports Java EE 6's
ManagedBean
and JSR-330'sNamed
annotations, if available. Note that Spring component annotations always override such standard annotations.If the annotation's value doesn't indicate a bean name, an appropriate name will be built based on the short name of the class (with the first letter lower-cased). For example:
com.xyz.FooServiceImpl -> fooServiceImpl

Method Detail
generateBeanName
public String generateBeanName(BeanDefinition definition, BeanDefinitionRegistry registry)
Description copied from interface:BeanNameGenerator
Generate a bean name for the given bean definition.- Specified by:
generateBeanName
in interfaceBeanNameGenerator
- Parameters:
definition
- the bean definition to generate a name forregistry
- the bean definition registry that the given definition is supposed to be registered with- Returns:
- the generated bean name
determineBeanNameFromAnnotation
protected String determineBeanNameFromAnnotation(AnnotatedBeanDefinition annotatedDef)
Derive a bean name from one of the annotations on the class.- Parameters:
annotatedDef
- the annotation-aware bean definition- Returns:
- the bean name, or
null
if none is found
isStereotypeWithNameValue
protected boolean isStereotypeWithNameValue(String annotationType, Set<String> metaAnnotationTypes, Map<String,Object> attributes)
Check whether the given annotation is a stereotype that is allowed to suggest a component name through its annotationvalue()
.- Parameters:
annotationType
- the name of the annotation class to checkmetaAnnotationTypes
- the names of meta-annotations on the given annotationattributes
- the map of attributes for the given annotation- Returns:
- whether the annotation qualifies as a stereotype with component name
buildDefaultBeanName
protected String buildDefaultBeanName(BeanDefinition definition, BeanDefinitionRegistry registry)
Derive a default bean name from the given bean definition.The default implementation delegates to
buildDefaultBeanName(BeanDefinition)
.- Parameters:
definition
- the bean definition to build a bean name forregistry
- the registry that the given bean definition is being registered with- Returns:
- the default bean name (never
null
)
buildDefaultBeanName
protected String buildDefaultBeanName(BeanDefinition definition)
Derive a default bean name from the given bean definition.The default implementation simply builds a decapitalized version of the short class name: e.g. "mypackage.MyJdbcDao" -> "myJdbcDao".
Note that inner classes will thus have names of the form "outerClassName.InnerClassName", which because of the period in the name may be an issue if you are autowiring by name.
- Parameters:
definition
- the bean definition to build a bean name for- Returns:
- the default bean name (never
null
)
