方法详细资料

hasAnnotatedMethods

default boolean hasAnnotatedMethods(String annotationName)

Determine whether the underlying class has any methods that are annotated (or meta-annotated) with the given annotation type.

参数:

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

getAnnotatedMethods

Set<MethodMetadata> getAnnotatedMethods(String annotationName)

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.

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.

introspect

static AnnotationMetadata introspect(Class<?> type)

Factory method to create a new AnnotationMetadata instance for the given class using standard reflection.

参数:

type - the class to introspect

返回:

a new AnnotationMetadata instance
