将Websocket连接链接到Spring Security中登录的用户

服务器端： 我有一个webSocket配置，如下所示：

@Configuration
@EnableWebSocketMessageBroker
@ComponentScan(basePackages = "gestionprojet.java")
public class WebSocketConfig extends AbstractWebSocketMessageBrokerConfigurer {

  @Override
  public void configureMessageBroker(MessageBrokerRegistry config) {
    config.enableSimpleBroker("/notification");
    config.setApplicationDestinationPrefixes("/app");
  }

  @Override
  public void registerStompEndpoints(StompEndpointRegistry registry) {
    registry.addEndpoint("/stomp").withSockJS();
  }

  protected void configureInbound(MessageSecurityMetadataSourceRegistry messages) {
      messages
              .simpDestMatchers("/user/*").authenticated() ;
  }
}

我还准备了一个spring安全配置，并使用自定义UserDetails接口与数据库集成进行用户管理：

@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(prePostEnabled = true)
public class WebSecurityConfig extends WebSecurityConfigurerAdapter{

@Autowired
@Qualifier("customUserDetailsService")
private UserDetailsService userDetailsService;

@Autowired
public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
  auth.userDetailsService(userDetailsService);

}

@Override
protected void configure(HttpSecurity http) throws Exception {

  http.csrf().disable()
      .authorizeRequests()
        .antMatchers("/login", "/logout").permitAll()
        .anyRequest().authenticated()
        .and().formLogin()
        .and()
        .sessionManagement().maximumSessions(1).sessionRegistry(sessionRegistry());

}

@Bean
public SessionRegistry sessionRegistry() {

    return new SessionRegistryImpl();
}

}

正如您所看到的，我已经实现了一个“SessionRegistry”，这样我就可以获得登录的用户

在客户端：

    var startListener = function() {
    socket.stomp.subscribe(service.NOTIFICATION_TOPIC, function(data) {
        listener.notify(getMessage(data.body));
    });
};

var initialize = function() {
    socket.client = new SockJS(service.SOCKET_URL);
    socket.stomp = Stomp.over(socket.client);
    socket.stomp.connect({}, startListener);
    socket.stomp.onclose = reconnect;
};

initialize();
return service;

我的问题是：我想将WebSocket连接链接到他们各自的登录用户（会话），这样我就可以通过WebSocket向特定用户发送删除消息，其中包括：

webSocketMessageTemplate.convertAndSend("/notification/message", new WebSocketMessage(n));

欢迎提出任何建议。多谢各位
