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's Named
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
Component.value()
,
Repository.value()
,
Service.value()
,
Controller.value()
,
Named.value()

)protected String buildDefaultBeanName(BeanDefinition 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.
