我有ACtiveMQ Artemis,HA配置为Replation,具有代理集群,每个主机有3个主机和3个从机。它们在6台不同的机器上运行。
我想知道如何看起来像经纪人URL?我应该使用所有6经纪人还是我应该只使用大师在boker网址?
ActiveMQConnectionFactory factory = new ActiveMQConnectionFactory("(tcp://amq1:61616,tcp://amq2:61616,tcp://amq3:61616,tcp://amq4:61616,tcp://amq5:61616,tcp://amq6:61616)?ha=true&retryInterval=1000&retryIntervalMultiplier=1.0&reconnectAttempts=-1");

Apache ActiveMQ Artemis客户端在连接后会收到所有实时和备份服务器的信息,因此如果客户端-实时服务器连接出现连接失败,客户端将检测到这一点并重新连接到备份服务器。这意味着仅在boker url中使用主服务器可以工作,但是如果没有一个主服务器处于活动状态会发生什么?
客户端将无法连接,因此将备份添加到boker url将允许客户端在没有主服务器处于活动状态时进行连接。
