Я пытаюсь использовать Websockets и STOMP 1.2. Я хочу аутентифицировать пользователя с помощью JWT в кадре CONNECT и вернуть сообщение об ошибке, если авторизация недействительна. Вот канал перехватчик
@Configuration
@EnableWebSocketMessageBroker
public class WebSocketConfig implements WebSocketMessageBrokerConfigurer
{
// ... Removed for readability
@Override
public void configureClientInboundChannel(ChannelRegistration registration)
{
registration.interceptors(new ChannelInterceptor()
{
@Override
public Message<?> preSend(Message<?> message, MessageChannel channel)
{
StompHeaderAccessor accessor =
MessageHeaderAccessor.getAccessor(message, StompHeaderAccessor.class);
if (accessor != null && StompCommand.CONNECT.equals(accessor.getCommand()))
{
String token = accessor.getFirstNativeHeader(authorizationHeader);
if (token != null)
{
Authentication authentication = tokenUtil.getAuthentication(resolveToken(token));
accessor.setUser(authentication);
}
else
{
throw new UnauthorizedException();
}
}
return message;
}
});
}
}
Таким образом, стек ошибок будет иметь

И аналогичная ошибка будет отправлена клиенту, и соединение будет закрыто.
Но после того, как соединение закрыто, другая трассировка стека записывается как вывод:

Понятия не имею, откуда взялся AccessDeniedException и как мне с этим справиться.
Если я не добавлю UnauthorizedException в метод preSend, клиент будет подключен, и когда он попытается что-то отправить, он получит AccessDeniedException, потому что все конечные точки требуют аутентифицированного пользователя, а затем соединение будет закрыто и трассировка стека для AccessDeniedException напечатана несколько раз.
Что я здесь делаю неправильно и как правильно обращаться с этим вариантом использования?
