AvatarMQ是基于Netty构建的分布式消息队列系统，支持多个生产者和多个消费者之间的消息路由、传递。

• AvatarMQ基于Java语言进行编写，网络通讯依赖Netty。
• 若干个消费者可以组成一个消费者集群，生产者可以向这个消费者集群投递消息。并且每个消费者只消费自己关注的生产者发送的消息。
• 支持动态新增、删除生产者、消费者。
• 消息投递支持负载均衡策略。
• 消息处理转发服务器（AvatarMQServerStartup）基于异步多线程消息队列进行组织架构，并且和Spring无缝集成。
• 生产者、消费者测试用例参考：com.newlandframework.avatarmq.test包。
• 启动AvatarMQ的消息处理转发服务器（AvatarMQServerStartup）之后，才能进行分布式消息队列系统的消息路由、传递。
• 基于Netty的主从事件线程池模型，网络传输中的消息序列化采用Kryo序列化框架，进一步提升消息序列化性能。
• Broker消息的投递，目前支持严格的消息顺序。其中Broker还支持消息的缓冲派发，即Broker会缓存一定数量的消息之后，再批量分配给对此消息感兴趣的消费者。

AvatarMQ is a distributed message queue system based on Netty(java nio framework), which supports message routing and delivery between multiple producers and multiple consumers.

• AvatarMQ based on the preparation of Java language, network communications rely on Netty.
• A number of consumers can form a consumer cluster, the producer can send messages to this consumer cluster. And each consumer only consumes the message that is sent by the producer.
• To support the dynamic add, delete the producers, consumers.
• Message delivery support load balancing strategy.
• Message processing and forwarding server (AvatarMQServerStartup) based on asynchronous multi thread message queue organization architecture, and seamless integration with Spring.
• Producer, consumer test case reference: com.newlandframework.avatarmq.test package.
• Start AvatarMQ message processing and forwarding server (AvatarMQServerStartup), in order to carry out the distributed message queue system message routing, delivery.
• Based on the Netty master slave event thread pool model, network transmission in the message serialization using Kryo serialization framework, to further enhance the performance of message serialization.
• Broker message delivery, currently supports strict message order. Broker also supports message buffer distribution, that is, Broker will cache a certain number of messages, and then batch distribution to the message of interest to consumers.

This simple example for AvatarMQ Producer:

package com.newlandframework.avatarmq.test;

import com.newlandframework.avatarmq.msg.Message;
import com.newlandframework.avatarmq.msg.ProducerAckMessage;
import com.newlandframework.avatarmq.producer.AvatarMQProducer;
import org.apache.commons.lang3.StringUtils;

public class AvatarMQProducer {

    public static void main(String[] args) throws InterruptedException {
        AvatarMQProducer producer = new AvatarMQProducer("127.0.0.1:18888", "AvatarMQ-Topic-1");
        producer.setClusterId("AvatarMQCluster");
        producer.init();
        producer.start();

        System.out.println(StringUtils.center("AvatarMQProducer 消息发送开始", 50, "*"));

        for (int i = 0; i < 1; i++) {
            Message message = new Message();
            String str = "Hello AvatarMQ From Producer1[" + i + "]";
            message.setBody(str.getBytes());
            ProducerAckMessage result = producer.delivery(message);
            if (result.getStatus() == (ProducerAckMessage.SUCCESS)) {
                System.out.printf("AvatarMQProducer 发送消息编号:%s\n", result.getMsgId());
            }

            Thread.sleep(100);
        }

        producer.shutdown();
        System.out.println(StringUtils.center("AvatarMQProducer 消息发送完毕", 50, "*"));
    }
}

This simple example for AvatarMQ Consumer:

package com.newlandframework.avatarmq.test;

import com.newlandframework.avatarmq.consumer.AvatarMQConsumer;
import com.newlandframework.avatarmq.consumer.ProducerMessageHook;
import com.newlandframework.avatarmq.msg.ConsumerAckMessage;
import com.newlandframework.avatarmq.msg.Message;

public class AvatarMQConsumer {

    private static ProducerMessageHook hook = new ProducerMessageHook() {
        public ConsumerAckMessage hookMessage(Message message) {
            System.out.printf("AvatarMQConsumer 收到消息编号:%s,消息内容:%s\n", message.getMsgId(), new String(message.getBody()));
            ConsumerAckMessage result = new ConsumerAckMessage();
            result.setStatus(ConsumerAckMessage.SUCCESS);
            return result;
        }
    };

    public static void main(String[] args) {
        AvatarMQConsumer consumer = new AvatarMQConsumer("127.0.0.1:18888", "AvatarMQ-Topic-1", hook);
        consumer.init();
        consumer.setClusterId("AvatarMQCluster");
        consumer.receiveMode();
        consumer.start();
    }
}
