参数:

annotationName - the fully qualified class name of the meta-annotation type to look for

返回:

the meta-annotation type names

hasAnnotation

public boolean hasAnnotation(String annotationName)

从接口复制的说明: AnnotationMetadata

Determine whether an annotation of the given type is present on the underlying class.

指定者:

hasAnnotation 在接口中 AnnotationMetadata

参数:

annotationName - the fully qualified class name of the annotation type to look for

返回:

true if a matching annotation is present

hasMetaAnnotation

public boolean hasMetaAnnotation(String metaAnnotationType)

从接口复制的说明: AnnotationMetadata

Determine whether the underlying class has an annotation that is itself annotated with the meta-annotation of the given type.

指定者:

hasMetaAnnotation 在接口中 AnnotationMetadata

参数:

metaAnnotationType - the fully qualified class name of the meta-annotation type to look for

返回:

true if a matching meta-annotation is present

isAnnotated

public boolean isAnnotated(String annotationName)

从接口复制的说明: AnnotatedTypeMetadata

Determine whether the underlying element has an annotation or meta-annotation of the given type defined.

If this method returns true, then AnnotatedTypeMetadata.getAnnotationAttributes(java.lang.String) will return a non-null Map.

指定者:

isAnnotated 在接口中 AnnotatedTypeMetadata

参数:

annotationName - the fully qualified class name of the annotation type to look for

返回:

whether a matching annotation is defined

getAnnotationAttributes

public AnnotationAttributes getAnnotationAttributes(String annotationName)

从接口复制的说明: AnnotatedTypeMetadata

Retrieve the attributes of the annotation of the given type, if any (i.e. if defined on the underlying element, as direct annotation or meta-annotation), also taking attribute overrides on composed annotations into account.

指定者:

getAnnotationAttributes 在接口中 AnnotatedTypeMetadata

参数:

annotationName - the fully qualified class name of the annotation type to look for

返回:

a Map of attributes, with the attribute name as key (e.g. "value") and the defined attribute value as Map value. This return value will be null if no matching annotation is defined.

getAnnotationAttributes

public AnnotationAttributes getAnnotationAttributes(String annotationName,

指定者:

getAnnotationAttributes 在接口中 AnnotatedTypeMetadata

参数:

annotationName - the fully qualified class name of the annotation type to look for

classValuesAsString - whether to convert class references to String class names for exposure as values in the returned Map, instead of Class references which might potentially have to be loaded first

返回:

a Map of attributes, with the attribute name as key (e.g. "value") and the defined attribute value as Map value. This return value will be null if no matching annotation is defined.

getAllAnnotationAttributes

public MultiValueMap<String,Object> getAllAnnotationAttributes(String annotationName)
