- org.springframework.web.method.ControllerAdviceBean

All Implemented Interfaces:
Ordered
```
public class ControllerAdviceBean
extends 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, a ControllerAdviceBean may be created from any object, including ones without an @ControllerAdvice.
