Jmx客户端抛出InstanceNotFoundException

Question

我有一个Jmx客户端,用于测试我写的jmx bean.这是客户端的代码:

    JMXServiceURL url = new JMXServiceURL("service:jmx:rmi:///jndi/rmi://localhost:8686/jmxrmi");
    JMXConnector jmxc = JMXConnectorFactory.connect(url, null);

    MBeanServerConnection mbsc = jmxc.getMBeanServerConnection();
    ObjectName mbeanName = new ObjectName("com.spmsoftware.processing.ping:type=ProcessingPing");

    ProcessingPing mbeanProxy = JMX.newMBeanProxy(mbsc, mbeanName, ProcessingPing.class, true);
    System.out.println("\nResult = " + mbeanProxy.ping(346, 0).getResultCode());

    jmxc.close();

ProcessingPing及其所有依赖项都存在于IntelliJ库中.

我的jmx bean是:

    public interface ProcessingPing {

        public PingResult ping(Integer environmentId, Integer timeout);
    }

和

    @Service("ProcessingPing")
    @ManagedResource(description = "")
    public class ProcessingPingImpl implements ProcessingPing {

        private static final Integer DEFAULT_TIMEOUT = 5000;

        @Autowired
        private PingProcessService pingProcessService;

        @Override
        @ManagedOperation(description = "")
        public PingResult ping(Integer environmentId, Integer timeout) {
            return pingProcessService.run(environmentId, timeout);
        }            
    }

在运行客户端时,我在尝试调用ping方法时遇到异常:

我不明白为什么jmx似乎能够获取bean,而不是类的实际实例.我猜这是一个类路径问题,但找不到它.作为一个方面,当使用JConsole进行测试时,它可以正常工作.

谢谢

看起来用于注册MBean的对象名称与尝试检索托管bean时使用的对象名称不同.

尝试检查JConsole中的对象名称.
