@ControllerAdvice
The @ControllerAdvice
annotation is a component annotation allowing implementation classes to be auto-detected through classpath scanning. It is automatically enabled when using the MVC namespace or the MVC Java config.
// Target all Controllers annotated with @RestController @ControllerAdvice(annotations = RestController.class) public class AnnotationAdvice {} // Target all Controllers within specific packages @ControllerAdvice("org.example.controllers") public class BasePackageAdvice {} // Target all Controllers assignable to specific classes @ControllerAdvice(assignableTypes = {ControllerInterface.class, AbstractController.class}) public class AssignableTypesAdvice {}

You can declare an @ExceptionHandler
method within an @ControllerAdvice
class in which case it handles exceptions from @RequestMapping
methods from many controllers.
