public class HandlerMethod
extends java.lang.Object
The class may be created with a bean instance or with a bean name (e.g. lazy-init bean,
prototype bean). Use createWithResolvedBean()
to obtain a HandlerMethod
instance with a bean instance resolved through the associated BeanFactory
.

the bean name is resolved before a
HandlerMethod is created and returned. |

getBridgedMethod()
If the bean method is a bridge method, this method returns the bridged
(user-defined) method.

getMethod()
Returns the method for this handler method.
|
<A extends java.lang.annotation.Annotation> |
getMethodAnnotation(java.lang.Class<A> annotationType)
Returns a single annotation on the underlying method traversing its super methods
if no annotation can be found on the given method itself.
