Double connections for one consumer - rabbitmq

Question

I am a new user of RabbitMQ and I really enjoy it but I have an issue (well it doesn't throw any error and it doesn't affect anything except my mind ...).
Each time I run a consumer, it creates 2 connections. I can't find why so I am asking for your help.
I am using Spring-Boot and Spring AMQP (maybe it because of Spring ...)
Here is the code :
receiver-context.xml
<?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:rabbit="http://www.springframework.org/schema/rabbit"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd

<rabbit:connection-factory id="connectionFactory" host="localhost" username="admin" password="admin" />
<bean id="receiver" class="com.test.Receiver" />

<constructor-arg name="delegate" ref="receiver"/>

</bean>
<bean id="container" class="org.springframework.amqp.rabbit.listener.SimpleMessageListenerContainer" >

<property name="defaultRequeueRejected" value="false" />
</bean>
AMQPPoCReceiverApplication.java
#SpringBootApplication
#ImportResource("classpath:com.test/rabbit-receiver-context.xml")
public class AMQPPoCReceiverApplication implements CommandLineRunner {
private AnnotationConfigApplicationContext context;
#Override
public void run(String... strings) throws Exception {
context = new AnnotationConfigApplicationContext(AMQPPoCReceiverApplication.class);
System.out.println("Waiting for message");
}
#Override
protected void finalize() throws Throwable {
super.finalize();
this.context.close();
}
public static void main(String[] args) {
SpringApplication.run(AMQPPoCReceiverApplication.class, args);
}
}
Receiver.java
public class Receiver {
public void receiveMessage(String message) {
System.out.println("Message received : " + message);
}
}
Here the logs at the start (notice the lines with the double '*'):

And here the double connections:
If I stop the client, it closes both (that is why I am sure it's a double connections for the same consumer).
If you need more information, ask here and I will reply as soon as possible.
Thank you all for any kind of help.

Answer 1

The answer is simple : I created 2 contexts in the same application.
new AnnotationConfigApplicationContext(AMQPPoCReceiverApplication.class);
and
SpringApplication.run(AMQPPoCReceiverApplication.class, args);
Only create one and it's done !
