接口 AnnotatedTypeMetadata

方法详细资料

• getAnnotations

  MergedAnnotations getAnnotations()

  Return annotation details based on the direct annotations of the underlying element.

  返回:

  merged annotations based on the direct annotations

  从以下版本开始:

  5.2

• isAnnotated

  default 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

  @Nullable
  default 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

  @Nullable
  default 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

  @Nullable
  default 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.

                                                                        boolean classValuesAsString)

  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

  classValuesAsString - whether to convert class references to String

  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.
