要解决ActiveMQ Artemis集群故障转移问题,可以采用以下步骤和代码示例:
元素配置集群连接。例如:
tcp://localhost:61616
netty-connector
netty-connector
org.apache.activemq.artemis:broker="mybroker",component=cluster,name="my-cluster"
的MBean来获取集群成员的信息。MBeanServerConnection mbsc = ManagementFactory.getPlatformMBeanServer();
ObjectName clusterObjectName = new ObjectName("org.apache.activemq.artemis:broker=\"mybroker\",component=cluster,name=\"my-cluster\"");
Set members = (Set) mbsc.getAttribute(clusterObjectName, "Members");
for (ObjectName member : members) {
String nodeId = (String) mbsc.getAttribute(member, "NodeId");
String nodeAddress = (String) mbsc.getAttribute(member, "NodeAddress");
boolean live = (boolean) mbsc.getAttribute(member, "Live");
// 处理集群成员的状态信息
}
org.apache.activemq.artemis.api.core.client.FailoverConnectionFactory
来创建连接工厂,并使用org.apache.activemq.artemis.api.core.client.FailoverConfiguration
来配置故障转移策略。FailoverConfiguration failoverConfig = new FailoverConfiguration(Arrays.asList("tcp://localhost:61616", "tcp://otherhost:61616"));
FailoverConnectionFactory factory = new FailoverConnectionFactory(failoverConfig);
Connection connection = factory.createConnection();
// 使用连接进行消息发送和接收
通过以上步骤和代码示例,可以实现ActiveMQ Artemis集群的故障转移功能。
