方法详细资料

isAnnotated

boolean isAnnotated(String annotationName)

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

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

参数:

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

返回:

whether a matching annotation is defined

getAnnotationAttributes

Map<String,Object> getAnnotationAttributes(String annotationName)

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.

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

Map<String,Object> getAnnotationAttributes(String annotationName,
                                           boolean classValuesAsString)

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.

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

MultiValueMap<String,Object> getAllAnnotationAttributes(String annotationName)

Retrieve all attributes of all annotations of the given type, if any (i.e. if defined on the underlying element, as direct annotation or meta-annotation). Note that this variant does not take attribute overrides into account.

参数:

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

返回:

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