Comment

 the Controller-Level @ExceptionHandler
Solution 2: the HandlerExceptionResolver
Solution 3: @ControllerAdvice
Solution 4: ResponseStatusException (Spring 5 and Above)
Handle the Access Denied in Spring Security
REST and Method-Level Security
Spring Boot provides an ErrorController implementation to handle errors in a sensible way.
