Spring aws-cloud SNS http end point confirm subscription not working

Question

In my spring boot aws-cloud SNS http end point confirm subscription is not working. When SNS confirmation comes following error coming in my application. Error :

[Request processing failed; nested exception is java.lang.IllegalArgumentException: Invoked method public abstract void org.springframework.cloud.aws.messaging.endpoint.NotificationStatus.confirmSubscription() is no accessor method!] with root cause
    java.lang.IllegalArgumentException: Invoked method public abstract void org.springframework.cloud.aws.messaging.endpoint.NotificationStatus.confirmSubscription() is no accessor method!
        at org.springframework.util.Assert.notNull(Assert.java:115) ~[spring-core-4.2.4.RELEASE.jar!/:4.2.4.RELEASE]
        at org.spring

My controller handler is :

     @NotificationSubscriptionMapping
        public void handleSubscriptionMessage( NotificationStatus status)   throws IOException {
            //Confirming SNS subscription
            status.confirmSubscription();
        }

My Pom contains following :

     <dependency>
          <groupId>org.springframework.cloud</groupId>
          <artifactId>spring-cloud-aws-messaging</artifactId>
          <version>1.0.4.RELEASE</version>
        </dependency>

        <!-- For Spring AWS autoconfiguration-->
        <dependency>
          <groupId>org.springframework.cloud</groupId>
          <artifactId>spring-cloud-aws-autoconfigure</artifactId>
          <version>1.0.4.RELEASE</version>
        </dependency>

I followed the explanation in this link

Answer 1

Did you specify the custom resolver:

<mvc:annotation-driven>
    <mvc:argument-resolvers>
        <ref bean="notificationResolver" />
    </mvc:argument-resolvers>
</mvc:annotation-driven>

<aws-messaging:notification-argument-resolver id="notificationResolver" />

Also, I cannot see the controller mapping, but in tutorial there is a statement:

Currently it is not possible to define the mapping URL on the method level therefore the RequestMapping must be done at type level and must contain the full path of the endpoint.
