将传统的消息生成/队列转换为反应器中的流量

// 示例代码：定义事件
class Event {
    private String type;
    private Object data;

    // getters and setters
}

// 示例代码：定义处理器接口
interface EventHandler {
    void handle(Event event);
}

// 示例代码：实现具体的处理器
class MessageHandler implements EventHandler {
    @Override
    public void handle(Event event) {
        // 处理消息逻辑
    }
}

// 示例代码：实现反应器
class Reactor {
    private Map<String, EventHandler> handlers = new HashMap<>();

    public void registerHandler(String eventType, EventHandler handler) {
        handlers.put(eventType, handler);
    }

    public void handleEvent(Event event) {
        EventHandler handler = handlers.get(event.getType());
        if (handler != null) {
            handler.handle(event);
        }
    }
}

// 示例代码：集成队列
class QueueReactor {
    private Reactor reactor;
    private Queue<Event> queue;

    public QueueReactor(Reactor reactor) {
        this.reactor = reactor;
        this.queue = new LinkedList<>();
    }

    public void enqueue(Event event) {
        queue.add(event);
    }

    public void processEvents() {
        while (!queue.isEmpty()) {
            Event event = queue.poll();
            reactor.handleEvent(event);
        }
    }
}
