Package org.springframework.context.annotation

Class FullyQualifiedAnnotationBeanNameGenerator

java.lang.Object

org.springframework.context.annotation.AnnotationBeanNameGenerator

org.springframework.context.annotation.FullyQualifiedAnnotationBeanNameGenerator

All Implemented Interfaces:

BeanNameGenerator

public class FullyQualifiedAnnotationBeanNameGenerator
extends AnnotationBeanNameGenerator

An extension of AnnotationBeanNameGenerator that uses the fully qualified class name as the default bean name if an explicit bean name is not supplied via a supported type-level annotation such as @Component (see AnnotationBeanNameGenerator for details on supported annotations).

Favor this bean naming strategy over AnnotationBeanNameGenerator if you run into naming conflicts due to multiple autodetected components having the same non-qualified class name (i.e., classes with identical names but residing in different packages).

Note that an instance of this class is used by default for configuration-level import purposes; whereas, the default for component scanning purposes is a plain AnnotationBeanNameGenerator.

Since:

5.2.3

public FullyQualifiedAnnotationBeanNameGenerator()

Method Details

buildDefaultBeanName

protected String buildDefaultBeanName(BeanDefinition definition)

Description copied from class: AnnotationBeanNameGenerator

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.

Overrides:

buildDefaultBeanName in class AnnotationBeanNameGenerator

Parameters:

definition - the bean definition to build a bean name for

Returns:

the default bean name (never null)
