Passer plusieurs paramètres à un une méthode get

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:

package com.password.generator.controller;
 
import java.util.ArrayList;
 
import org.springframework.http.HttpStatus;
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
 
import com.password.generator.contracts.PasswordGeneratorAbstract;
import com.password.generator.service.ComputerPasswordGenerator;
 
@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

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

Comment puis je procéder s'il vous plaît?

Merci

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

Merci pour ta réponse,

Finalement j'ai réussis je passe les paramètres dans l'url avec getMappinget je récupère avec PathVariable
