是否可以在运行时访问Java 8类型信息？

是否可以在运行时访问Java 8类型信息？

是的，有可能。表示这种结构的反射类型称为

AnnotatedParameterizedType

。这是如何获取注释的示例：

// get the email field Field emailAddressField = MyClass.class.getDeclaredField("emailAddresses");// the field's type is both parameterized and annotated,// cast it to the right type representationAnnotatedParameterizedType annotatedParameterizedType =        (AnnotatedParameterizedType) emailAddressField.getAnnotatedType();// get all type parametersAnnotatedType[] annotatedActualTypeArguments =         annotatedParameterizedType.getAnnotatedActualTypeArguments();// the String parameter which contains the annotationAnnotatedType stringParameterType = annotatedActualTypeArguments[0];// The actual annotationAnnotation emailAnnotation = stringParameterType.getAnnotations()[0];System.out.println(emailAnnotation);  // @Email()
