JMX操作ActiveMQ(1)

我們知道ActiveMQ broker的管理介面是通過JMX方式提供的。

一個簡單的訪問方式就是通過jconsole，輸入

service:jmx:rmi:///jndi/rmi://localhost:1099/jmxrmi

需要注意的是：

1、預設JMX功能是沒有開啟的，需要在activemq.xml的broker配置上添加useJmx="true"

2、需要在managementContext裡，修改為createConnector="true"，（同時這裡也可以修改jmx的連接埠和domain）

（參見http://activemq.apache.org/jmx.html）

通過jconsole來操作還是不太方便。特別是某些時候我們需要把對broker和queue的管理整合到我們的管理系統中去。

這時候我們就需要通過JMX的編程介面來與broker進行互動了。

可以先寫一個小程式，看看broker的jmx中都提供了什麼東西。

package kk;import java.util.Iterator;import java.util.Set;import javax.management.MBeanAttributeInfo;import javax.management.MBeanInfo;import javax.management.MBeanOperationInfo;import javax.management.MBeanServerConnection;import javax.management.ObjectInstance;import javax.management.ObjectName;import javax.management.remote.JMXConnector;import javax.management.remote.JMXConnectorFactory;import javax.management.remote.JMXServiceURL;public class TestJMX {public static void main(String[] args) throws Exception {String surl = "service:jmx:rmi:///jndi/rmi://localhost:1099/jmxrmi";JMXServiceURL url = new JMXServiceURL(surl);JMXConnector jmxc = JMXConnectorFactory.connect(url, null);MBeanServerConnection mbsc = jmxc.getMBeanServerConnection();System.out.println("Domains:---------------");String domains[] = mbsc.getDomains();for (int i = 0; i < domains.length; i++) {System.out.println("\tDomain[" + i + "] = " + domains[i]);}System.out.println("all ObjectName：---------------");Set<ObjectInstance> set = mbsc.queryMBeans(null, null);for (Iterator<ObjectInstance> it = set.iterator(); it.hasNext();) {ObjectInstance oi = (ObjectInstance) it.next();System.out.println("\t" + oi.getObjectName());}System.out.println("org.apache.activemq:BrokerName=localhost,Type=Broker：---------------");ObjectName mbeanName = new ObjectName("org.apache.activemq:BrokerName=localhost,Type=Broker");MBeanInfo info = mbsc.getMBeanInfo(mbeanName);System.out.println("Class: " + info.getClassName());if (info.getAttributes().length > 0){for(MBeanAttributeInfo m : info.getAttributes())System.out.println("\t ==> Attriber：" + m.getName());}if (info.getOperations().length > 0){for(MBeanOperationInfo m : info.getOperations())System.out.println("\t ==> Operation：" + m.getName());}jmxc.close();}}

輸出結果：

上面只是拿到了broker的屬性和操作，同理也可以拿到其它對象的屬性和巨集指令清單。
根據這些，我們就可以拿到broker，connector，producer，consumer，queue，topic，Subscription等等的Object對象，進一步的操作他們。

待續。
