Provide mechanism for just mapping an exception to a status code and use the default error handling afterwards

[mvitz]

If an exception is directly annotated with @ResponseStatus(HttpStatus.NOT_FOUND) the default error page handling works and a provided template at error/404.html is rendered.

However when using a custom @ControllerAdvice for exception mapping the template isn't rendered because it's now the developers responsibility.

What I want is a mechanisms which just allows me to map any exception (which I can not or do not want to annotate) to a HTTP status code and let the default error handling take over the template resolution.

The application at https://github.com/mvitz/spring-boot-exception-handling can be used to demonstrate the current behaviour.

I just found #7329 which is in some way related.

Indeed, this is a duplicate of #7329 - closing this now.

I'm not sure that this is exactly a duplicate of #7329. It would be nice to do something to help with this (even if it's just better documentation).

@ExceptionHandler(CustomException.class)
void handleCustomExcepption(HttpServletResponse response) throws IOException {
    response.sendError(HttpStatus.NO_CONTENT.value());
}

won't produce default error message as of Spring Boot 1.5.5

Update: my own fault (or misundestanding): no response was generated for NO_CONTENT (204) status code, after switching to any other code the response is there.

@ZaitsevY You've already said that once. There's no need to spam multiple issues with the same comment.

@wilkinsona excuse, please, I duplicated after having understood that the first comment went to the closed issue.
