如何关闭JAVA客户端和Active-MQ队列之间的特定套接字

Question

I have to test a specific scenario by closing the Active-MQ consumer socket without killing the java client process and Active-MQ server. what is the best way to close specific socket between JAVA client and Active-MQ queue?

Answer 1

maybe by calling org.apache.activemq.ActiveMQMessageConsumer.close() or org.apache.activemq.ActiveMQConnection.close() to close all sessions of consumers/producers

UPDATE you can use VisualVM and call stop method,

Please consider that if your client is using failover he will reconnect automatically

or by code like below

to close 1 consumer by ID or RemoteAddress

 import java.util.HashMap; import java.util.Map; import java.util.Set; import javax.management.MBeanServerConnection; import javax.management.MBeanServerInvocationHandler; import javax.management.ObjectName; import javax.management.remote.JMXConnector; import javax.management.remote.JMXConnectorFactory; import javax.management.remote.JMXServiceURL; import org.apache.activemq.broker.jmx.ConnectionViewMBean; public class JMXCloseConsumer { public static void main(String[] args) throws Exception { JMXServiceURL url = new JMXServiceURL("service:jmx:rmi:///jndi/rmi://localhost:1099/jmxrmi"); Map<String, String[]> env = new HashMap<>(); String[] creds = { "admin", "admin" }; env.put(JMXConnector.CREDENTIALS, creds); JMXConnector jmxc = JMXConnectorFactory.connect(url, env); MBeanServerConnection conn = jmxc.getMBeanServerConnection(); ObjectName conName = new ObjectName( "org.apache.activemq:type=Broker,brokerName=localhost,connector=clientConnectors,connectorName=openwire,connectionViewType=clientId,connectionName=*"); Set connections = conn.queryNames(conName, null); Object[] c = connections.toArray(); for (int s = 0; s < c.length; s++) { ObjectName con = (ObjectName) c[s]; System.out.println(con.toString()); ConnectionViewMBean connectionView = MBeanServerInvocationHandler.newProxyInstance(conn, con, ConnectionViewMBean.class, true); String address = connectionView.getRemoteAddress(); System.out.println(address); connectionView.stop(); } } } 

to close all consumers by connector name

import java.util.HashMap;
import java.util.Iterator;
import java.util.Map;

import javax.management.MBeanServerConnection;
import javax.management.MBeanServerInvocationHandler;
import javax.management.ObjectName;
import javax.management.remote.JMXConnector;
import javax.management.remote.JMXConnectorFactory;
import javax.management.remote.JMXServiceURL;

import org.apache.activemq.broker.jmx.BrokerViewMBean;
import org.apache.activemq.broker.jmx.ConnectorViewMBean;

public class JMXCloseAllConsumers {

    public static void main(String[] args) throws Exception {
        JMXServiceURL url = new JMXServiceURL("service:jmx:rmi:///jndi/rmi://localhost:1099/jmxrmi");
        Map<String, String[]> env = new HashMap<>();
        String[] creds = { "admin", "admin" };
        env.put(JMXConnector.CREDENTIALS, creds);
        JMXConnector jmxc = JMXConnectorFactory.connect(url, env);
        MBeanServerConnection conn = jmxc.getMBeanServerConnection();
        ObjectName activeMq = new ObjectName("org.apache.activemq:type=Broker,brokerName=localhost");
        BrokerViewMBean mbean = MBeanServerInvocationHandler.newProxyInstance(conn, activeMq, BrokerViewMBean.class,
                true);
        Map<String, String> props = mbean.getTransportConnectors();
        for (Iterator<?> iter = props.keySet().iterator(); iter.hasNext();) {
            String name = (String) iter.next();
            String value1 = props.get(name);
            System.out.println(value1);
            ObjectName connector = new ObjectName(
                    "org.apache.activemq:type=Broker,brokerName=localhost,connector=clientConnectors,connectorName="
                            + name);

            ConnectorViewMBean connectorViewMBean = MBeanServerInvocationHandler.newProxyInstance(conn, connector,
                    ConnectorViewMBean.class, true);
            System.out.println(connectorViewMBean.connectionCount());
            if (connectorViewMBean.connectionCount() > 0) {
                connectorViewMBean.stop();
            }
        }
    }
}
