Question

我的配置XML：appconfig.xml

<beans xmlns="...">

   <context:mbean-server/>
   <bean id="exporter" class="org.springframework.jmx.export.MBeanExporter" lazy-init="false">
        <property name="beans">
            <map>
                <entry key="bean:name=notificationSender" value-ref="notificationSenderImpl"></entry>
                <entry key="bean:name=notificationListener" value-ref="notificationListenerImpl"></entry>
            </map>
        </property>
    <property name="notificationListenerMappings">
                    <map>
                <entry key="notificationListenerImpl" value-ref="notificationListenerImpl"></entry>
            </map>              
        </property>

        <property name="server" ref="mbeanServer"/>    
    </bean>
    <bean id="notificationSender" class="com....NotificationSenderImpl"/>
    <bean id="notificationListener" class="com....NotificationListenerImpl"/>

我的代码： Test.java

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("classpath:appconfig.xml")
public class Test {
    @Autowired
    private ConfigurableApplicationContext context;

    @Test
    public void testFlow() {
        NotificationSender sender = (NotificationSender) context.getBean("notificationSender");     
                sender.send();
    }

    @After
    public void tearDown(){
        context.close();
    }

}

类NotificationSenderImpl.java

public class NotificationSenderImpl implements NotificationPublisherAware{

       private NotificationPublisher notificationPublisher; 

    public void setNotificationPublisher(NotificationPublisher notificationPublisher) {
        // TODO Auto-generated method stub
        this.notificationPublisher = notificationPublisher;     
    }

    public void send(){
        notificationPublisher.sendNotification(new Notification("simple", this, 0L));
    }
}

和listener ...类NotificationListenerImpl

public class NotificationListenerImpl implements NotificationListener{

    public void handleNotification(Notification notification, Object handback) {

        // TODO Auto-generated method stub
        System.out.println("Notification received");
    }

}

正在发送通知但未收到通知。有什么指针吗？

不确定您是否已解决此问题，但我会看看是否可以提供帮助。我最近一直在玩spring / JMX而且还是新手，但希望我能分享一些见解。

我认为您不需要将侦听器声明为要导出的MBean，只需要将要发布通知的bean声明。其次，我相信notificationListenerMappings中的键应该是MBean的ObjectName，而不是对侦听器bean本身的引用。换句话说..

<bean id="exporter" class="org.springframework.jmx.export.MBeanExporter" lazy-init="false">
    <property name="beans">
        <map>
            <entry key="bean:name=notificationSender" value-ref="notificationSenderImpl"></entry>
        </map>
    </property>
    <property name="notificationListenerMappings">
        <map>
            <entry key="bean:name=notificationSender" value-ref="notificationListenerImpl"></entry>
        </map>              
    </property>
    <property name="server" ref="mbeanServer"/>    
</bean>

您还可以将通配符用于侦听器映射键。这是我自己的MBeanExporter的一个例子，它从我所有的注释声明的MBeans中获取通知：

<bean id="exporter" class="org.springframework.jmx.export.MBeanExporter">
    .
    .
    .
    <property name="notificationListenerMappings">
        <map>
            <entry key="*">
                <bean class="com.poc.jmx.domain.NotificationBroadcastListener" />
            </entry>
        </map>
    </property>
</bean>

希望有所帮助。
