Passer plusieurs paramètres à un une méthode get

**kevin254kl** · 10/08/2019, 18h10

Bonjour à tous,

Pourriez-vous m'aider s'il vous plaît?

C'est pour un projet d'une api rest pour générer des mots de passes.
J'aimerais donc une méthode get avec les paramètres (nombre de mot depasse longueur) mais les seul exemple que je trouve sont des mappings avec un seul paramètres.
Mon controller ou j'ai tester

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

@RestController
@RequestMapping(value = "/passwords")
public class PasswordController {
 
	@GetMapping(params = {"userId", "toto"})
    public ResponseEntity<String> passwords(@PathVariable(value = "userId") int userId, @PathVariable(value = "toto") String toto/*@PathVariable(required = false) int length, @PathVariable(required = false) int number*/) 
    {return new ResponseEntity<String>( toto,HttpStatus.ACCEPTED);
 
       //return new ResponseEntity<ArrayList<String>>(getPasswords(length, number), HttpStatus.ACCEPTED);
    }
 
    private ArrayList<String> getPasswords(int length, int number)
    {
    	PasswordGeneratorAbstract passwordGenerator = new ComputerPasswordGenerator();
    	passwordGenerator.setLength(length);
		return passwordGenerator.passwordGenerator(number);
 
    }
 
}

Mais j'ai cette erreur

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

Salut,
Tu utilise quoi comme techno pour le front ?
Tu peux montrer le code du service qui appel cette méthode ?
