启动后访问（ActiveMQ必须提前启动）

http://localhost:8044/doc.html

与topic发送端联合交互测试topic订阅 (不是持久化)

发送端发送

订阅端查看临时数据(不是持久化的，因此接收数据需要先启动的)

再看控制台a和b都收到了数据

持久化订阅

持久化订阅在springboot activemq里需要配置

我这里新建了一个发布端两个订阅端 topic_client1 topic_client2 topic = myw_topic_p

    // topic模式的ListenerContainer
    @Bean
    public JmsListenerContainerFactory<?> jmsListenerContainerTopic(ConnectionFactory activeMQConnectionFactory) {
        DefaultJmsListenerContainerFactory bean = new DefaultJmsListenerContainerFactory();
        // pubSubDomain 表示开启发布订阅域
        bean.setPubSubDomain(true);
        // 开启持久订阅。即下线后重新上线依然能继续接收Topic消息
        bean.setSubscriptionDurable(true);
        // 持久订阅的Client端标识(多个端持久订阅需要保证唯一性，否则可能会出现问题)
        bean.setClientId("topic_client1");
        bean.setConnectionFactory(activeMQConnectionFactory);

        return bean;
    }

    // topic模式的ListenerContainer
    @Bean
    public JmsListenerContainerFactory<?> jmsListenerContainerTopic(ConnectionFactory activeMQConnectionFactory) {
        DefaultJmsListenerContainerFactory bean = new DefaultJmsListenerContainerFactory();
        // pubSubDomain 表示开启发布订阅域
        bean.setPubSubDomain(true);
        // 开启持久订阅。即下线后重新上线依然能继续接收Topic消息
        bean.setSubscriptionDurable(true);
        // 持久订阅的Client端标识(多个端持久订阅需要保证唯一性，否则可能会出现问题)
        bean.setClientId("topic_client2");
        bean.setConnectionFactory(activeMQConnectionFactory);
        return bean;
    }

    public static final String defaultTopic = "myw_topic_p";

代码目录

把三个应用分别启动我用了swagger UI因此可以在浏览器里访问到

发送端
http://localhost:8045/doc.html

订阅端1
http://localhost:8046/doc.html

订阅端2
http://localhost:8047/doc.html

在这里发送端发送消息，订阅端1和订阅端2都可以收到消息的

发送消息三条

蚂蚁舞1
蚂蚁舞2
蚂蚁舞3

订阅端1和订阅端2的控制台输出，表示都收到了三条消息，那么发布订阅模式是可以的

持久化测试一，订阅端1关停，此时订阅端2能正常收到发送端的消息

蚂蚁舞4
蚂蚁舞5
蚂蚁舞6

订阅端2的控制台

在ActiveMQ上

此时启动订阅端1，测试持久化,可以看到之前发送的(蚂蚁舞4 蚂蚁舞5 蚂蚁舞6都收到了)

持久化测试二，订阅端1和订阅端2都关停，先发送三条消息到ActiveMQ上,然后把ActiveMQ给关停后启动(重启，验证ActiveMQ有没有保存消息)

蚂蚁舞7
蚂蚁舞8
蚂蚁舞9

关停重启

启动订阅端1和启动订阅端2

订阅端1

订阅端2

可以看到订阅端1和订阅端2都收到了蚂蚁舞7 8 9三条消息
