    • StandardAnnotationMetadata

      public StandardAnnotationMetadata(Class<?> introspectedClass, boolean nestedAnnotationsAsMap)
      Create a new StandardAnnotationMetadata wrapper for the given Class, providing the option to return any nested annotations or annotation arrays in the form of AnnotationAttributes instead of actual Annotation instances.
      参数:
      introspectedClass - the Class to introspect
      nestedAnnotationsAsMap - return nested annotations and annotation arrays as AnnotationAttributes for compatibility with ASM-based AnnotationMetadata implementations

    • getAnnotations

      public MergedAnnotations getAnnotations()
      从接口复制的说明: AnnotatedTypeMetadata
      Get annotation details based on the direct annotations and meta-annotations of the underlying element.
      指定者:
      getAnnotations 在接口中 AnnotatedTypeMetadata
      返回:
      merged annotations based on the direct annotations and meta-annotations

    • getAnnotationTypes

      public Set<String> getAnnotationTypes()
      从接口复制的说明: AnnotatedTypeMetadata
      Get the fully qualified class names of all annotation types that are present on the underlying class.
      指定者:
      getAnnotationTypes 在接口中 AnnotatedTypeMetadata
      返回:
      the annotation type names

    • getAnnotationAttributes

      @Nullable public Map<String,Object> getAnnotationAttributes(String annotationName, boolean classValuesAsString)
      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).

      @AliasFor semantics are fully supported, both within a single annotation and within annotation hierarchies.

      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 each annotation attribute name as map key (e.g. "location") and the attribute's value as map value; or null if no matching annotation is found

    • getAllAnnotationAttributes

      @Nullable public MultiValueMap<String,Object> getAllAnnotationAttributes(String annotationName, boolean classValuesAsString)
      从接口复制的说明: AnnotatedTypeMetadata
      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.
      指定者:
      getAllAnnotationAttributes 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
      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.

    • hasAnnotatedMethods

      public boolean hasAnnotatedMethods(String annotationName)
      从接口复制的说明: AnnotationMetadata
      Determine whether the underlying class has any methods that are annotated (or meta-annotated) with the given annotation type.
      指定者:
      hasAnnotatedMethods 在接口中 AnnotationMetadata
      参数:
      annotationName - the fully qualified class name of the annotation type to look for

    • getAnnotatedMethods

      public Set<MethodMetadata> getAnnotatedMethods(String annotationName)
      从接口复制的说明: AnnotationMetadata
      Retrieve the method metadata for all methods that are annotated (or meta-annotated) with the given annotation type.

      For any returned method, AnnotatedTypeMetadata.isAnnotated(java.lang.Class<? extends java.lang.annotation.Annotation>) will return true for the given annotation type.

      指定者:
      getAnnotatedMethods 在接口中 AnnotationMetadata
      参数:
      annotationName - the fully qualified class name of the annotation type to look for
      返回:
      a set of MethodMetadata for methods that have a matching annotation. The return value will be an empty set if no methods match the annotation type.
