Spring @ExceptionHandler handling multiple kinds of exceptions

Question

I can't figure out how to handle more than one kind of exception by @ExceptionHandler.

I need to programmatically deal with these exceptions, for this I'd need a shared reference. Is this done via this reference "Exception ex" ? I don't think so, cause the exception is not caught like this, how would I do it then ?

I can't put all the exception references as arguments to the handler method, it wouldn't make sense, it can't be programmatically dealt with. I need a shared reference so that I could use "instanceof" on it or just send it somewhere else as a general "Exception"

@ExceptionHandler({DescriptionCstOrderException.class, SpecializationCstOrderException.class, NoUploadFileException.class,                     DeadLineCstOrderException.class, DocumentCstOrderException.class, CommentCstOrderException.class}) public String handleFormException(Exception ex, ActionRequest actionRequest) {     logger.error(ex.getMessage());     SessionErrors.add(actionRequest, ex.getClass().getName());       return "mainOrderForm";   } 

Additional question: what if I wanted to handle org.springframework.web.multipart.MaxUploadSizeExceededException, that is not thrown from any method of the handler? Because @ExceptionHandler catches only exceptions that are thrown from one of the handler methods.

The exceptionHandler method could be placed into some extended parent controller but if one uses only defaultAnnotationHandlerMapping... ?

Appreciate any help, I'm going crazy, this is very frustrating....

Answer 1

The @ExceptionHandler value can be set to an array of Exception types.

The implementation of using exception array as mentioned in Spring documentation will be like:

@ExceptionHandler({     NotFoundException.class,     MissingServletRequestParameterException.class  })
