inbound-channel-adapter's auto-startup feature is not working

[sashi202]

Hi,

I want the inbound-channel-adapter in disabled mode when the spring context is started.
Application will start up the endpoint later.

To accomplish that I set my inbound-channel-adapter's auto-startup to false in spring context file.
But it is not working. Spring is simply ignoring the auto-startup setting and starting the endpoint.

However I was able to stop the endpoint later by calling Lifecycle.stop, but I do not want the endpoint started when the app is started.

Here is my spring context file:

<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
	xmlns:int="http://www.springframework.org/schema/integration"
	xsi:schemaLocation="http://www.springframework.org/schema/beans 
		http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
		http://www.springframework.org/schema/integration
		http://www.springframework.org/schema/integration/spring-integration-2.0.xsd">
					
		<bean id="uuidBean" class="java.util.UUID" factory-method="randomUUID"/>
		
		<int:inbound-channel-adapter 
			id="uuidGenerator"
			auto-startup="false" 
			channel="uuidChannel"
			ref="uuidBean" 
			method="randomUUID">
			
			<int:poller fixed-delay="1000" />
			
		</int:inbound-channel-adapter>
		
		
		<bean id="java.lang.System.out"
       		class="org.springframework.beans.factory.config.FieldRetrievingFactoryBean"/>
		
		<int:service-activator 
			ref="java.lang.System.out" 
			method="println" 
			input-channel="uuidChannel"/>
		
</beans>

Here is my main program:

package auto_startup;

import org.springframework.context.Lifecycle;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class StartApp {
	
	public static void main(String[] args) {
		try {
			
			ClassPathXmlApplicationContext appCtx = 
				new ClassPathXmlApplicationContext("test-ctx.xml");
			appCtx.start();
			
			System.out.println("\nSleeping for 5 seconds\n");
			Thread.sleep(5000);
			
			System.out.println("\nStopping the endpoint uuidGenerator\n");
			Lifecycle lc = appCtx.getBean("uuidGenerator", Lifecycle.class);
			lc.stop();
			System.out.println("\nSuccessfully stopped endpoint uuidGenerator.\n");
			
			System.out.println("\nSleeping forever. You should not see any " +
					"UUID's on the console\n");
			Thread.sleep(Long.MAX_VALUE);
			
		} catch(Exception e) {
			e.printStackTrace();
		}
	}

}

I attached the maven project too. Please help

Thanks,

When you call start() on the context, that will start any Lifecycle bean. What "auto" startup means is that the bean will start itself even without the call being made. So, can you try just removing your call to start()?

Mark,

It works. I misunderstood the auto startup feature. Thank you for the prompt response.
