Now, App can return a cutstom 404 page.
@ControllerAdvice
class GlobalControllerExceptionHandler {
@ResponseStatus(HttpStatus.NOT_FOUND)
@ExceptionHandler(NoHandlerFoundException.class)
public String handle404(WebRequest request) {
return "/exceptions/404";
}
}
And I wonder how should I do, if I want to get a JSON when Accept request header is Accept: application/json, like this:
$> curl -H "Accept: application/json" http://localhost:8080/no-such-page
{"timestamp":"2018-04-11T05:56:03.845+0000","status":404,"error":"Not Found","message":"No message available","path":"/no-such-page"}```
