如何設置JMX通知監聽器？

這是How to stop message processing before undeploying?如何設置JMX通知監聽器？

我想配置取消部署事件JMX通知監聽器的後續，但我不知道如何正確設置的MBean名稱。我們目前正在使用JBoss 4.2.3。以下嘗試不會觸發任何通知。

<mbean code="jboss.example.NotificationListener" 
     name="jboss.example:name=NotificationListener"> 
    <attribute name="SubscriptionList"> 
     <subscription-list> 
      <mbean name="jboss.j2ee:service=EjbModule,type=jmx.attribute.change"> 
      </mbean> 
      <notification type="JBOSS_MONITOR_NOTIFICATION"></notification> 
     </subscription-list> 
    </attribute> 
</mbean>

這裏是所有通知事件，其中上彈出取消部署的列表：

2011-05-05 09:06:27,236 INFO [STDOUT] Stop NotificationListener.

我認爲這將是最好趕在第一個事件，所以我要趕：

2011-05-05 09:06:09,022 INFO [STDOUT] Got notification: javax.management.AttributeChangeNotification[source=jboss.j2ee:service=EjbModule,module=simple-mdb-ejb-1.0.0-SNAPSHOT.jar][type=jmx.attribute.change][message=EjbModule stopping], handback: null

有什麼建議嗎？使用示例的JBoss的NotificationListener和假定一個EJB3 MDB deploymentas

嗨克里斯; 您使用的是EJB 2.x嗎？我問，因爲EJB 2.x MDB管理接口比EJB 3有點複雜，因爲它包含對象名稱中的序列號，當我在日誌摘錄中看到它時，它使我認爲您在EJB 2中：jndiName = local/SimpleMessageEJB @ 30208588 – Nicholas 2011-05-09 14:50:39

哦，我使用了一個我在網上找到的示例項目。我會重構它。在真正的項目中，我們使用EJB3。 – 2011-05-10 06:07:46

如下：

EAR：myear.ear
JAR：myjar.jar
MDB名稱：MyMDB

部署描述符聽者的MBean會是這樣：

<server> 
    <mbean code="jboss.example.NotificationListener" 
      name="jboss.example:name=NotificationListener"> 
     <attribute name="SubscriptionList">  
     <subscription-list> 
      <mbean name="jboss.j2ee:ear=myear.ear,jar=myjar.jar,service=EJB3,name=MyMDB" handback="MyMDB"> 
      <notification type="jmx.attribute.change"> 
      </mbean> 
     </subscription-list> 
     </attribute> 
    </mbean> 
    </server>

如果你簡單地記錄通知的的toString停止MDB時，它會是這個樣子：

狀態3（入門） - >狀態1（停止）

NOTIFICATION:<[email protected] 
attributeName=State attributeType=java.lang.Integer **oldValue=3 newValue=1 
type=jmx.attribute.change** sequenceNumber=7 timeStamp=1305033720266 userData=null 
message=MdbDelegateWrapper stopping 
source=jboss.j2ee:ear=myear.ear,jar=myear.jar,name=MyMDB,service=EJB3 
source=jboss.j2ee:ear=myear.ear,jar=myear.jar,name=MyMDB,service=EJB3>

狀態1（停止） - >狀態0（停止）

NOTIFICATION:<[email protected] attributeName=State 
attributeType=java.lang.Integer **oldValue=1 newValue=0 type=jmx.attribute.change** 
sequenceNumber=8 timeStamp=1305033720320 userData=null 
message=MdbDelegateWrapper stopped 
source=jboss.j2ee:ear=myear.ear,jar=myear.jar,name=MyMDB,service=EJB3 
source=jboss.j2ee:ear=myear.ear,jar=myear.jar,name=MyMDB,service=EJB3>

謝謝。你從哪裏得到你的知識？我搜索了幾個小時，但沒有找到訂閱列表元素的唯一解釋。 – 2011-05-10 14:31:50
