Logging in via postman works fine ONLY when using application/x-www-form-urlencoded
Trying to do the same request with raw-json doesn't work.
Anyway I'm trying to implement the login to my react app. When i have the request set as:
      const response = await Axios.post(`${window.ipAddress.ip}/login`,
        JSON.stringify({ email: email.toLowerCase(), password: password }),
        { headers: { 'Content-Type': 'application/x-www-form-urlencoded' } }
      );
From this in springboot the UserService class gets called which shows:
    public UserDetails loadUserByUsername(String email) throws UsernameNotFoundException {
        User user = findUserByEmail(email);
        if ( user != null){
            Collection<SimpleGrantedAuthority> authorities = new ArrayList<>();
            user.getRoles().forEach(role -> { authorities.add(new SimpleGrantedAuthority(role.getName()));});
            return new org.springframework.security.core.userdetails.User(user.getEmail(), user.getPassword(), authorities);
        }
        else{ throw new EntityNotFoundException("Entity not found"); }
    }
It then shows email as "NONE_PROVIDED" and ultimately failing.
The second issue is I don't actually have a /login route in controller code when searching through all files so I'm unsure at which point it actually calls this method through springboot.
The only changes I made from the default spring-security implementation is the use of my own class where I use "email" in place of "userName".
Any suggestions are welcome.
Edit:
