`@RestControllerAdvice` is a shortcut annotation that combines `@ControllerAdvice`
with `@ResponseBody`, in effect simply an `@ControllerAdvice` whose exception handler
methods render to the response body.
On startup, `RequestMappingHandlerMapping` and `ExceptionHandlerExceptionResolver` detect
controller advice beans and apply them at runtime. Global `@ExceptionHandler` methods,
