Could you specify which lifecycle your Bean is implementing ? Also, Is this a singleton Bean or prototype Bean? 

According to documentation -- <a href="https://docs.mulesoft.com/mule-user-guide/v/3.7/developing-components#component-lifecycle" rel="nofollow noreferrer">https://docs.mulesoft.com/mule-user-guide/v/3.7/developing-components#component-lifecycle</a>

You could implement the interface org.mule.api.lifecycle.Callable and just with the method onCall, trigger any operation. 

Example:

<pre><code> public class MyClass implements Callable {

@Override
public Object onCall(MuleEventContext eventContext) throws Exception {
 //DO SOMETHING
 //Call STOP method
 return eventContext.getMessage().getPayload();
}}
</code></pre>

try to listen to the MuleContextNotification and wait for a CONTEXT_STOPPING action to trigger your TCP call.

See example below: 

<pre><code>public class MuleContextListener implements MuleContextNotificationListener&lt;MuleContextNotification&gt;,MuleContextAware {

 private MuleContext context;
 private final static Logger logger = LogManager.getLogger(MuleContextListener.class);

 @Override
 public void onNotification(MuleContextNotification notification) {
 logger.info("NOTIFICATION RECEIVED!!!!!");
 logger.info(MuleContextNotification.getActionName(notification.getAction()));
 if(notification.getAction() == MuleContextNotification.CONTEXT_STOPPING ){
 //replace with your tcp call 
 logger.info(" MY ACTION HAS BEEN TRIGGER");
 }
 }

 @Override
 public void setMuleContext(MuleContext context) {
 this.context = context;
 }
}
</code></pre>

For testing I have another bean that that implements lifecycle Stoppable...

<pre><code>public class ClassStopLc implements Stoppable {

 @Override
 public void stop() throws MuleException {
 logger.info(" ClassStopLC Stopping");
 }
</code></pre>

If I check my logs: 

<pre><code>2017-03-22 16:08:26,827 [[mulecontextaware].mulecontextawareFlow.1.02] INFO mulecontextaware.MuleContextListener - NOTIFICATION RECEIVED!!!!!

Not sure if the stopping stage will allow you to make the TCP call without any problem, could you try and let me know? I am quite curious :)

I have a bean in Mule that needs to send a message before a TCP endpoint is disconnected on shutdown. The bean implements Lifecycle and is configured with "depends-on=connector," but it seems like the "depends-on" has no effect on the shutdown order. The endpoint is no longer connected when the stop method is called on my bean. Is there a way for the "stop" method to be called on my bean before it is called on the endpoint or connector? I'm using Mule 3.7 CE.

Spring bean depends on mule endpoint

我在Mule中有一个bean，它需要在TCP端点关机时断开连接之前发送消息。该bean实现了生命周期，并配置了“depends on =connector”，但看起来“depends on”对关闭顺序没有影响。在我的bean上调用stop方法时，端点不再连接。在端点或连接器上调用"stop“方法之前，有没有办法在bea...
