Spring boot @ClientEndpoint can't @Autowired my service

Question

I try to use @Autowired to use my service in @ClientEndpoint

but there is a java.lang.NullPointerException

here's my code

P2PService.java

public interface P2PService {

    void send(Session session, String msg);
}

P2PServiceImpl.java

@Service
public class P2PServiceImpl implements P2PService {
    @Override
    public void send(Session session, String msg) {
        session.getAsyncRemote().sendText(msg);
    }
}

Firstly I use this code

@Component
@ClientEndpoint
public class P2pClient {
    private Session session;
    public void connectServer(String url) {
            try {
                WebSocketContainer container = ContainerProvider.getWebSocketContainer();
                URI uri = URI.create(url);

                this.session = container.connectToServer(P2pClient.class, uri);

            } catch (Exception e) {
                e.printStackTrace();
            }
        }
    @Autowired
    private P2PService p2PService;


    @OnOpen
    public void onOpen(Session session) {
        this.session = session;
        System.out.println(this);
        System.out.println(P2pClient.p2PService);
    }

and after find reference I use this

    private static P2PService p2PService;
    @Autowired
    public static void setP2PService(P2PService p2PService) {
        P2pClient.p2PService = p2PService;
    }

and console output is

com.p2ptest.P2pClient@71e7a66b
null

I just use this code to start the project

P2pClient p2pClient = new P2pClient();
p2pClient.connectServer(url);

Exception

I don't know what I can do
