Validation failed for object='statutProduits'. Error count: 2

Question

When i'm trying to submit my form i get this errors, well i need to create an object "status_product"

Whitelabel Error Page

This application has no explicit mapping for /error, so you are seeing this as a fallback.

Thu Dec 07 04:07:23 GMT+01:00 2017 There was an unexpected error (type=Bad Request, status=400). Validation failed for object='statutProduits'. Error count: 2

I am having trouble finding the two validation errors show on the error page. I am pretty lost at this point. Hopefully someone can help me out, its preventing me from making progress at the moment.

Answer 1

In your case, you have added server-side validation but in your controller, you didn't check that conditions and blindly saving that object into your database. instead of doing like that check the conditions in the controller by using BindingResult

 @RequestMapping(value="/save", method=RequestMethod.POST)
 public String save( Model model, @Validated StatutProduits statproduit BindingResult bindingResult) {
     if(bindingResult.hasErrors()){
         return "to same page to shows error fields";
     }
    statutproduitsrepository.save(statproduit);
    return "Confirmation";
 }
