JWT & Spring Boot

Hello, I develop a website and I have some questions for the connexion with users. For the back-end, I use Spring Boot and I have this function :

 @PostMapping("/login")
    public ResponseEntity<?> loginUser(@RequestBody User user) {
        User userFound = userRepository.findByEmail(user.getEmail());
        if(userFound == null) {
            return ResponseEntity.status(HttpStatus.UNAUTHORIZED).body("Email non trouvé");
        }

        if(!passwordEncoder.matches(user.getPassword(), userFound.getPassword())) {
            return ResponseEntity.status(HttpStatus.UNAUTHORIZED).body("Mot de passe incorrect");
        }

        return ResponseEntity.ok("Login effectué");
    }

 @PostMapping("/login")
    public ResponseEntity<?> loginUser(@RequestBody User user) {
        User userFound = userRepository.findByEmail(user.getEmail());
        if(userFound == null) {
            return ResponseEntity.status(HttpStatus.UNAUTHORIZED).body("Email non trouvé");
        }

        if(!passwordEncoder.matches(user.getPassword(), userFound.getPassword())) {
            return ResponseEntity.status(HttpStatus.UNAUTHORIZED).body("Mot de passe incorrect");
        }

        return ResponseEntity.ok("Login effectué");
    }

I return this because I don't really know what to return. I would like use a JWT token and I search on the web and I don't understand what I have to do. Actually I would like a token and all the informations I need about the user (email, name etc...) , so what can I return and how to convert these datas in VueJS (I use Axios to recover the datas) ?
