如何从Spring WebSocket STOMP中的取消订阅帧中获取订阅目的地

import org.springframework.messaging.handler.annotation.MessageMapping;
import org.springframework.messaging.handler.annotation.SubscribeMapping;
import org.springframework.messaging.simp.annotation.SendToUser;
import org.springframework.messaging.simp.annotation.SubscribeMapping;
import org.springframework.messaging.simp.annotation.UnsubscribeMapping;
import org.springframework.messaging.simp.stomp.StompHeaderAccessor;
import org.springframework.stereotype.Controller;

@Controller
public class WebSocketController {

    @SubscribeMapping("/topic/{destination}")
    public void subscribeDestination(@DestinationVariable String destination, StompHeaderAccessor accessor) {
        // 处理订阅逻辑
    }

    @UnsubscribeMapping("/topic/{destination}")
    public void unsubscribeDestination(@DestinationVariable String destination, StompHeaderAccessor accessor) {
        String unsubscribedDestination = accessor.getDestination();
        // 在这里获取到取消订阅的目的地
    }
}
