Class ControllerAdviceBean

java.lang.Object

org.springframework.web.method.ControllerAdviceBean

All Implemented Interfaces:

Ordered

public class ControllerAdviceBean
extends java.lang.Object
implements Ordered

Encapsulates information about an @ControllerAdvice Spring-managed bean without necessarily requiring it to be instantiated.

The findAnnotatedBeans(ApplicationContext) method can be used to discover such beans. However, an ControllerAdviceBean may be created from any object, including ones without an @ControllerAdvice.

3.2
