Optional long parameter is present but cannot be translated into a null value
Hi i'm developing on web so i have an ajax function which calling to a controller function which calling to a DAO function (to make changes on DB). I'm getting the exception above in the controller function..
controller function:
@RequestMapping(value="/changeIsPublic", method=RequestMethod.GET, produces = MediaType.APPLICATION_JSON_VALUE)
public @ResponseBody boolean changeIsPublic(HttpServletRequest request, Locale locale, Model model, long transactionId, boolean isPublic) {
boolean result = false;
try {
boxDao.changeIsPublicStatus(transactionId, isPublic);
result = true;
} catch (Exception e) {
logger.debug("Failed to publish transaction. transaction ID: " + transactionId + e.getMessage());
}
return result;
}
DAO function:
public Box changeIsPublicStatus(long id, boolean isPublic) {
Criteria criteria = getCurrentSession().createCriteria(Box.class);
criteria.add(Restrictions.eq("id", id));
Box transaction = (Box) criteria.uniqueResult();
transaction.setIsPublic(isPublic);
return transaction;
}
exception:
SEVERE: Servlet.service() for servlet [appServlet] in context with path [/goblin] threw exception [Request processing failed; nested exception is java.lang.IllegalStateException: Optional long parameter 'transactionId' is present but cannot be translated into a null value due to being declared as a primitive type.

Answer
I got this error when I was working with Jackson REST web services (RESTful Spring Controllers). The problem was that I forgot the @PathVariable annotation which tells the web service where it should receive your input to produce the response so it did not know where I should be passing my input. My fix was:
@RequestMapping(value = "/supplier/{supplierId}")
public List<PurchaseInvoice> getPurchaseInvoicesBySupplierId(@PathVariable int supplierId) {
return purchaseInvoiceService.getPurchaseInvoicesBySupplierId(supplierId);
}
