Class HandlerMethod.HandlerMethodParameter

java.lang.Object
  org.springframework.core.MethodParameter
      org.springframework.web.method.HandlerMethod.HandlerMethodParameter

Enclosing class:

HandlerMethod

private class HandlerMethod.HandlerMethodParameter
extends MethodParameter

A MethodParameter that resolves method annotations even when the actual annotations are on a bridge method rather than on the current method. Annotations on super types are also returned via AnnotationUtils.findAnnotation(Method, Class).

Constructor Summary

HandlerMethod.HandlerMethodParameter(java.lang.reflect.Method method, int parameterIndex)

Method Summary

java.lang.Class<?>	getDeclaringClass() Return HandlerMethod.getBeanType() rather than the method's class, which could be important for the proper discovery of generic types.
<T extends java.lang.annotation.Annotation> T	getMethodAnnotation(java.lang.Class<T> annotationType) Return the method annotation via HandlerMethod.getMethodAnnotation(Class), which will find the annotation by traversing super-types and handling annotations on bridge methods correctly.

Method Detail

getDeclaringClass

public java.lang.Class<?> getDeclaringClass()

Return HandlerMethod.getBeanType() rather than the method's class, which could be important for the proper discovery of generic types.

Overrides:

getDeclaringClass in class MethodParameter

getMethodAnnotation

public <T extends java.lang.annotation.Annotation> T getMethodAnnotation(java.lang.Class<T> annotationType)

Return the method annotation via HandlerMethod.getMethodAnnotation(Class), which will find the annotation by traversing super-types and handling annotations on bridge methods correctly.

Overrides:

getMethodAnnotation in class MethodParameter

Parameters:

annotationType - the annotation type to look for

Returns:

the annotation object, or null if not found
