ActiveMQTo achieve the JMSspecification.

# ActiveMQ concepts related terms

  1. DestinationDestination
    where the message to be sent, including: Queueand Topicthey are on the Destinationinterface implementation
    1. PTPMode - Queue
    2. 发布订阅Mode - Topic
      MessageProviderneed to specify Destinationin order to send a message, MessageConsumeryou need to specify Destinationto receive and consume messages.
  2. ProducerNews producer
    news producer, responsible for sending the message to the destination Destination.
  3. ConsumerNews consumer
    news consumer, from the destination responsible for Destinationconsumer news.
  4. MessageMessage body
  5. ConnectionFactoryConnection factory
    factory is used to create connections
  6. ConnectionConnecting
    users to access ActiveMQ
  7. SessionSession
    time there is a state of lasting and effective access by Connectioncreating, supporting the specific operation is the basis of the message.
    JMSIt defines two messaging models: point to point (point to point, queue) and publish / subscribe (publish / the Subscribe, Topic) . The main difference is that is can be repeated consumption .

# JMS Queue in contrastive pattern Topic

Topic Queue
Overview Publish Subscribe messaging publish subscribe messaging Point-to-Point Point
Whether the state topic default data does not fall, it is stateless. Queue default data will be saved as a file on the server mq, such as Active MQ typically stored in $ AMQ_HOME \ data \ kr-store \ data below. You may be configured to store DB.
Integrity assurance Each publisher does not guarantee publication of data, Subscriber can receive. Queue ensure that each receiver is able to receive data.
Whether the message will be lost Generally when a publisher publish messages to a topic, only that topic is listening sub address can receive the message; if there is no sub listening, the topic is lost. Sender sends a message to the target Queue, receiver may receive messages asynchronously on this Queue. Message Queue on temporarily if no receiver to take, is not lost.
Receiving news release strategy Many receive policy news release, listen to multiple sub addresses the same topic can receive messages sent by the publisher. Sub mq after receiving notification server One to one to receive news release strategies, messages sent by a sender, a receiver only receives. After receiving the receiver, the server has received notification mq, mq server or take other actions to delete messages in the queue.

1. PTP Queue can not be repeated consumption

Message to message producers to produce the queue, then the queue is removed from the message consumer and consumer message.
After the message is the consumer (consumer ack response confirmation / transaction mode), queue storage is no longer there, so consumers can not consume the message to the message that has been consumed.
Queue supports multiple consumers, but for a message, it will only be a consumer can consume, others can not consume this news.
When consumers do not exist, the message will be saved until there is a consumer of consumer

2. Publish-Subscribe pattern can be repeated consumption Topic

消息生产者（发布）将消息发布到Topic中，同时有多个消息消费者（订阅该Topic）消费该消息。
和点对点方式不同，发布到topic的消息会被所有订阅者消费。
当生产者发布消息，不管是否有消费者。都不会保存消息。如果生产者向队列发送消息时，没有消费者订阅该队列，则消息全部丢失。否则向所有订阅了该Topic的消费者发送同样的消息(即：消费者必须在线)

# 在SpringBoot中使用ActiveMQ

ActiveMQ管理地址: http://localhost:8161/admin/

  1. PTP模式

    • 依赖

          //jms-active
    compile 'org.springframework.boot:spring-boot-starter-activemq'
    //active连接池-1.5.13依赖
    compile 'org.apache.activemq:activemq-pool'

    • 配置信息

      spring:
  # activemq
  activemq:
    broker-url: failover:(tcp://localhost:61616,tcp://localhost:666)?randomize=false      # tcp://localhost:61616/故障转移，默认情况下如果某个链接失效了，则从列表中随机获取一个，如果设置了randomize=false则是严格按照列表的先后顺序的
    user: admin           # 用户名
    password: admin       # 密码
    in-memory: false      # 基于内存的activemq
    close-timeout: 15s     # 在考虑结束之前等待的时间
    pool:
      enabled: true                               # 启动连接池(是否用Pooledconnectionfactory代替普通的ConnectionFactory)
      max-connections: 10                         # 最大链接数量
      idle-timeout: 60s                           # 空闲连接存活时间
      block-if-full: true                         # 当连接请求和池满时是否阻塞。设置false会抛“JMSException异常”
      block-if-full-timeout: -1                   # 如果池仍然满，则在抛出异常之前阻塞时间
      create-connection-on-startup: true          # 是否在启动时创建连接。可以在启动时用于加热池
      maximum-active-session-per-connection: 500  # 每个连接的有效会话的最大数目。
      reconnect-on-exception: true                # 当发生"JMSException"时尝试重新连接
  jms:
    pub-sub-domain: false                  # 默认情况下activemq提供的是queue模式，若要使用topic模式需要配置下面配置

    • 特点

      • 一条消息只会发送给其中某一个单独的消费者

      • 未被确认的消息将再次发送给其他消费

  2. 发布订阅模式

    • 发布订阅模式需要将spring.jms.pub-sub-domain=true，其他配置不需要修改

    • 定义发布订阅模式下的Destination - Topic

      /**

 */
@Configuration
public class ActiveMqConfig {
  /**
     * ActiveMQ topic的定义
     */
    public static class TopicDefinition {
        public static final String activeTestTopic = "active-test-topic";
        public static final String activeProdTopic = "active-prod-topic";
    }

    /**
     * 定义一个名为BeanName为activeTestTopic的Topic:active-test-topic
     *
     * @return
     */
    @Bean(name = "activeTestTopic")
    public ActiveMQTopic activeMQTestTopic() {
        return new ActiveMQTopic(TopicDefinition.activeTestTopic);
    }

    /**
     * 定义一个名为BeanName为activeProdTopic的Topic:active-prod-topic
     *
     * @return
     */
    @Bean(name = "activeProdTopic")
    public ActiveMQTopic activeMQProdTopic() {
        return new ActiveMQTopic(TopicDefinition.activeProdTopic);
    }
}
    @PostMapping("/ps/sender")
    public void pushTest(@RequestParam String msg) {
        activeMqProducer.send(msg);
    }

    • 发布订阅模式下的消费者定义

        String text = ((TextMessage) mqMessage.getMessage()).getText();
        log.info("testTopicConsumer2接收到activeMq-activeTestTopic消息:[{}]", text);
    }

# 参考资料

SpringBoot与ActiveMQ整合实现手动ACK(事务模式与ack应答模式)

# TODO：

  • 如何保证消费者将消息发送到ActiveMQ的过程中消息不丢失
  • ActiveMQ的集群与主从
  • 消息的持久化
  • 事务
  • PTP模式下消费者多久没ACK后ActiveMQ会认为该条消息消费失败呢？(是不是有个消费超时时间设置)。还是只能等到该消费者下线。
