return "login";
}
@GetMapping("/register")
public String registerGet(){
return "register";
}
@PostMapping("/register")
public String registerPost(@ModelAttribute("Utilisateur") Utilisateur Utilisateur, HttpServletRequest request)throws ServletException{
String password=Utilisateur.getPassword();
Utilisateur.setPasswordUtl(bCryptPasswordEncoder.encode(password));
List<Role> roles = new ArrayList<>();
roles.add(roleRepo.findById(2L).get());
Utilisateur.setRoles(roles);
utilisateurRepo.save(Utilisateur);
request.login(Utilisateur.getEmail(), password);

Solution
As per your error stacktrace
java.lang.IllegalArgumentException: rawPassword cannot be null
at org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder.encode(BCryptPasswordEncoder.java:107)
it simply means your password variable which you are passing to bCryptPasswordEncoder.encode(password) is coming as blank.
Utilisateur.setPasswordUtl(bCryptPasswordEncoder.encode(password));
and the only reason it will be blank after your forms are getting submitted from frontend because of
- You have not mapped your html attributes correctly with you Model attributes.
and hence you are getting null for those attributes and you are passing null to the encoder and its throwing error.
Correct your thymleaf html template as per below suggestions .
Change the html as below to map the details in your ModelAttribute correctly.
<div class="form-group">
<label for="password">Password</label>
<input type="password" class="form-control form-control-lg" required placeholder="Password"
name="passwordUtl"
id="password">
</div>
You are defining the html tags as name="password" whereas it should be as per your attributes defined in entity class name="passwordUtl".
Your entity class have diffrent named variables and you are using diffrent name in your html.
Correct all other html names as suggested above as per your entity class attribute names.
