JMX操作ActiveMQ(1)

我们知道ActiveMQ broker的管理接口是通过JMX方式提供的。

一个简单的访问方式就是通过jconsole，输入

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

需要注意的是：

1、默认JMX功能是没有打开的，需要在activemq.xml的broker配置上添加useJmx="true"

2、需要在managementContext里，修改为createConnector="true"，（同时这里也可以修改jmx的端口和domain）

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

通过jconsole来操作还是不太方便。特别是某些时候我们需要把对broker和queue的管理集成到我们的管理系统中去。

这时候我们就需要通过JMX的编程接口来与broker进行交互了。

可以先写一个小程序，看看broker的jmx中都提供了什么东西。

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();

	}

}

输出结果：

上面只是拿到了broker的属性和操作，同理也可以拿到其它对象的属性和操作列表。
根据这些，我们就可以拿到broker，connector，producer，consumer，queue，topic，Subscription等等的Object对象，进一步的操作他们。
