Activiti5.16.4版本中，添加了jmx模块，Activiti默认打开了jmx功能，关于如何禁用jmx功能，稍后进行说明。本文以activiti-jmx-5.21的使用为例详细说明：

使用jmx的时候，需要引入该模块的地址，Maven仓库地址为：

    org.activiti    activiti-jmx    5.21.0

引入之后，启动流程引擎如下所示：

public class App {
	// 获取到Activiti ProcessEngine
	ProcessEngine processEngine = null;
	// 获取RepositoryService 实例对象
	RepositoryService repositoryService = null;
	// 资源名称
	String resourceName = "shareniu_addInputStream.bpmn";
	IdentityService identityService;
	RuntimeService runtimeService;
	TaskService taskService;
	ActivitiEventDispatcher eventDispatcher;

	@Before
	public void init() {
		InputStream in = App.class.getClassLoader().getResourceAsStream(
				"com/shareniu/chapter16/activiti.cfg.xml");
		ProcessEngineConfiguration pcf = ProcessEngineConfiguration
				.createProcessEngineConfigurationFromInputStream(in);
		processEngine = pcf.buildProcessEngine();
		repositoryService = processEngine.getRepositoryService();
		identityService = processEngine.getIdentityService();
		runtimeService = processEngine.getRuntimeService();
		taskService = processEngine.getTaskService();
		ProcessEngineConfigurationImpl pc = (ProcessEngineConfigurationImpl) processEngine
				.getProcessEngineConfiguration();
		eventDispatcher = pc.getEventDispatcher();
	}

紧接着，开始测试jmx功能，如下所示：

@Test
	public void addInputStreamTest() throws IOException, MalformedObjectNameException, InstanceNotFoundException, MBeanException, ReflectionException, InterruptedException {
		
		JMXServiceURL url = new JMXServiceURL("service:jmx:rmi:///jndi/rmi://127.0.0.1:1099/jmxrmi/activiti");       
		JMXConnector jmxc = JMXConnectorFactory.connect(url, null);
		
		MBeanServerConnection mbsc  = jmxc.getMBeanServerConnection();
		Integer mBeanCount = mbsc.getMBeanCount();
		
		
		
		 ObjectName mbeanName = new ObjectName("org.activiti.jmx.Mbeans", "type", "Deployments");  
		Object invoke = mbsc.invoke(mbeanName, "getProcessDefinitions", null, null);
		 System.out.println(invoke);
		 List<list> result=(List<list>) invoke;
		 for (List list : result) {
			for (String string : list) {
				System.out.println(string);
			}
		}
		 Thread.sleep(Integer.MAX_VALUE);
		// ProcessDefinitionsMBean processDefinitionsMBean=new ProcessDefinitionsMBean(processEngine.getProcessEngineConfiguration());
		
		 
		 
		// processDefinitionsMBean.getProcessDefinitionById(id)
		/*mbsc.getObjectInstance("org.activiti.jmx.Mbeans");
		ObjectName mbeanName = new ObjectName("com.jmx.demo9:name=Hello");  
		
		System.out.println(mBeanCount);*/
		
	}

Activiti在使用jmx功能的时候，默认的服务URL为service:jmx:rmi:///jndi/rmi://127.0.0.1:1099/jmxrmi/activiti。然后我们打开jconsole工具（位于JDK安装目录中的bin目录下）如下图所示：
