org.springframework.context.annotation.AnnotationBeanNameGenerator

所有已实现的接口:

org.springframework.beans.factory.support.BeanNameGenerator

public class AnnotationBeanNameGenerator
extends Object
implements org.springframework.beans.factory.support.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

方法详细资料

generateBeanName

public String generateBeanName(org.springframework.beans.factory.config.BeanDefinition definition,
                               org.springframework.beans.factory.support.BeanDefinitionRegistry registry)

指定者:

generateBeanName 在接口中 org.springframework.beans.factory.support.BeanNameGenerator

determineBeanNameFromAnnotation

@Nullable
protected String determineBeanNameFromAnnotation(org.springframework.beans.factory.annotation.AnnotatedBeanDefinition annotatedDef)

Derive a bean name from one of the annotations on the class.

参数:

annotatedDef - the annotation-aware bean definition

返回:

the bean name, or null if none is found

isStereotypeWithNameValue

protected boolean isStereotypeWithNameValue(String annotationType,
                                            Set<String> metaAnnotationTypes,
                                            @Nullable
                                            Map<String,Object> attributes)

Check whether the given annotation is a stereotype that is allowed to suggest a component name through its annotation value().

参数:

annotationType - the name of the annotation class to check

metaAnnotationTypes - the names of meta-annotations on the given annotation

attributes - the map of attributes for the given annotation

返回:

whether the annotation qualifies as a stereotype with component name

buildDefaultBeanName

protected String buildDefaultBeanName(org.springframework.beans.factory.config.BeanDefinition definition,
                                      org.springframework.beans.factory.support.BeanDefinitionRegistry registry)

Derive a default bean name from the given bean definition.

The default implementation delegates to buildDefaultBeanName(BeanDefinition).

参数:

definition - the bean definition to build a bean name for

registry - the registry that the given bean definition is being registered with

返回:

the default bean name (never null)

buildDefaultBeanName

protected String buildDefaultBeanName(org.springframework.beans.factory.config.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.

参数:

definition - the bean definition to build a bean name for

返回:

the default bean name (never null)
