用java代码实现 hazelcast 队列，要求有3个生产者event,notification,config,分别使用3个消息队列 event queue,notification queue,config queue，分别由3个接收者event receiver, notification receiver,config receiver接收，接收后通过同一个线程分配各自的消费者，分别由3个消费者 event processor, notification processor,config processor进行处理，其中notification processor进行邮件的发送，config processor进行缓存的刷新，event processor有3种不同的处理，分别是存储到mysql数据库，单独发送邮件和批量发送邮件

以下是使用Java代码实现Hazelcast队列的示例，满足上述要求：

import com.hazelcast.core.Hazelcast;
import com.hazelcast.core.HazelcastInstance;
import com.hazelcast.core.IQueue;

public class HazelcastQueueExample {
    public static void main(String[] args) {
        // 创建 Hazelcast 实例
        HazelcastInstance hazelcastInstance = Hazelcast.newHazelcastInstance();
        
        // 创建 event queue
        IQueue<String> eventQueue = hazelcastInstance.getQueue("event");
        // 创建 event receiver
        EventReceiver eventReceiver = new EventReceiver(eventQueue);
        // 分配 event processor
        EventProcessor eventProcessor = new EventProcessor();
        // 设置 event processor 的处理方式
        eventProcessor.addProcessor(new StoreToMysqlProcessor());
        eventProcessor.addProcessor(new SendEmailProcessor());
        eventProcessor.addProcessor(new BatchSendEmailProcessor());
        // 启动 event receiver
        eventReceiver.start(eventProcessor);

        // 创建 notification queue
        IQueue<String> notificationQueue = hazelcastInstance.getQueue("notification");
        // 创建 notification receiver
        NotificationReceiver notificationReceiver = new NotificationReceiver(notificationQueue);
        // 分配 notification processor
        NotificationProcessor notificationProcessor = new NotificationProcessor(new SendEmailProcessor());
        // 启动 notification receiver
        notificationReceiver.start(notificationProcessor);

        // 创建 config queue
        IQueue<String> configQueue = hazelcastInstance.getQueue("config");
        // 创建 config receiver
        ConfigReceiver configReceiver = new ConfigReceiver(configQueue);
        // 分配 config processor
        ConfigProcessor configProcessor = new ConfigProcessor(new CacheRefreshProcessor());
        // 启动 config receiver
        configReceiver.start(configProcessor);
    }
}

// 定义接收器基类
abstract class Receiver implements Runnable {
    private final IQueue<String> queue;

    public Receiver(IQueue<String> queue) {
        this.queue = queue;
    }

    @Override
    public void run() {
        while (true) {
            try {
                String message = queue.take();
                // 分配处理器
                Thread thread = new Thread(getProcessor(message));
                thread.start();
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
        }
    }

    // 获取处理器
    abstract Processor getProcessor(String message);
}

// 定义 event receiver
class EventReceiver extends Receiver {
    public EventReceiver(IQueue<String> queue) {
        super(queue);
    }

    @Override
    Processor getProcessor(String message) {
        // 根据消息内容，分配不同的处理器
        if (message.contains("mysql")) {
            return new StoreToMysqlProcessor();
        } else if (message.contains("single-email")) {
            return new SendEmailProcessor();
        } else if (message.contains("batch-email")) {
            return new BatchSendEmailProcessor();
        } else {
            return null;
        }
    }
}

// 定义 notification receiver
class NotificationReceiver extends Receiver {
    public NotificationReceiver(IQueue<String> queue) {
        super(queue);
    }

    @Override
    Processor getProcessor(String message) {
        return new SendEmailProcessor();
    }
}

// 定义 config receiver
class ConfigReceiver extends Receiver {
    public ConfigReceiver(IQueue<String> queue) {
        super(queue);
    }

    @Override
    Processor getProcessor(String message) {
        return new CacheRefreshProcessor();
    }
}

// 定义处理器基类
abstract class Processor implements Runnable {}

// 定义 event processor
class EventProcessor extends Processor {
    private final List<Processor> processors = new ArrayList<>();

    public void addProcessor(Processor processor) {
        processors.add(processor);
    }

    @Override
    public void run() {
        for (Processor processor : processors) {
            Thread thread = new Thread(processor);
            thread.start();
        }
    }
}

// 定义 notification processor
class NotificationProcessor extends Processor {
    private final SendEmailProcessor sendEmailProcessor;

    public NotificationProcessor(SendEmailProcessor sendEmailProcessor) {
        this.sendEmailProcessor = sendEmailProcessor;
    }

    @Override
    public void run() {
        // 进行邮件的发送
        sendEmailProcessor.run();
    }
}

// 定义 config processor
class ConfigProcessor extends Processor {
    private final CacheRefreshProcessor cacheRefreshProcessor;

    public ConfigProcessor(CacheRefreshProcessor cacheRefreshProcessor) {
        this.cacheRefreshProcessor = cacheRefreshProcessor;
    }

    @Override
    public void run() {
        // 进行缓存的刷新
        cacheRefreshProcessor.run();
    }
}

// 定义存储到 MySQL 数据库的处理器
class StoreToMysqlProcessor extends Processor {
    @Override
    public void run() {
        // 处理存储到 MySQL 数据库的逻辑
    }
}

// 定义单独发送邮件的处理器
class SendEmailProcessor extends Processor {
    @Override
    public void run() {
        // 处理单独发送邮件的逻辑
    }
}

// 定义批量发送邮件的处理器
class BatchSendEmailProcessor extends Processor {
    @Override
    public void run() {
        // 处理批量发送邮件的逻辑
    }
}

// 定义缓存刷新的处理器
class CacheRefreshProcessor extends Processor {
    @Override
    public void run() {
        // 处理缓存刷新的逻辑
    }
}
