对于ActiveMQ Artemis主备切换的分裂脑问题，可通过在broker.xml中配置static-connectors来解决。具体实现方法如下：

1. 在broker.xml中配置static-connectors，以主备切换为例：

    
        master-connector
        
            slave-connector
        
    
    
        slave-connector
        
            master-connector
        
    



    
        
            
                master-connector
            
        
        
            
                slave-connector
            
        
    

2. 实现一个failover监听器，当主broker宕机后，自动将备broker转换为主broker，并将static-connectors的connector-ref改为新的主broker：

public class FailoverListener extends ActiveMQFailoverListener {

    @Override
    public void failoverEvent(FailoverEventType eventType) throws ActiveMQException {
        if (eventType == FailoverEventType.FAILURE_DETECTED) {
            // 主broker宕机，将备broker转换为主broker
            String newMasterBrokerUrl = "tcp://127.0.0.1:61617";
            ServerLocator serverLocator = ActiveMQClient.createServerLocator(newMasterBrokerUrl);
            ClientSessionFactory sessionFactory = serverLocator.createSessionFactory();
            ActiveMQConnectionFactory cf = new ActiveMQConnectionFactory(sessionFactory);
            // 改变static-connectors的connector-ref
            cf.getConnection().createSession().createQueue("artemis.dev.queue");
            System.err.println("Switched to the new master: " + new
