value to set the status and the body of the response. Such methods can also be declared
in `@ControllerAdvice` classes to apply them globally.
NOTE: Note that Spring WebFlux does not have an equivalent for the Spring MVC
`ResponseEntityExceptionHandler`, because WebFlux raises only `ResponseStatusException`
(or subclasses thereof), and those do not need to be translated to
an HTTP status code.
Applications that implement global exception handling with error details in the response
body should consider extending
{api-spring-framework}/web/reactive/result/method/annotation/ResponseEntityExceptionHandler.html[`ResponseEntityExceptionHandler`],
which provides handling for exceptions that Spring MVC raises and provides hooks to
customize the response body. To make use of this, create a subclass of
`ResponseEntityExceptionHandler`, annotate it with `@ControllerAdvice`, override the
necessary methods, and declare it as a Spring bean.
