I want to consume internal events that are published to the amq.rabbitmq.event such as client.connected, client.disconnected.
Below is my Spring Configuration:
<?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
http://www.springframework.org/schema/rabbit
http://www.springframework.org/schema/rabbit/spring-rabbit-1.0.xsd">
<rabbit:connection-factory id="connectionFactory" host="localhost"
username="guest" password="guest"/>
<rabbit:queue name="amqp.rabbitmq.events.client.connections.created"
id="amqp.rabbitmq.events.client.connections.created"
auto-delete="true" durable="false"/>
<rabbit:admin connection-factory="connectionFactory" auto-startup="true"/>
<rabbit:topic-exchange id="amq.rabbitmq.event" name="amq.rabbitmq.event" durable="true">
<rabbit:bindings>
<rabbit:binding queue="amqp.rabbitmq.events.client.connections.created" pattern="connection.created">
</rabbit:binding>
</rabbit:bindings>
</rabbit:topic-exchange>
<bean id="asyncListener" class="com.example.rabbitmq.com.tp.spring.amqp.rabbit.SpringAMQPRabbitAyncListener"/>
<rabbit:listener-container id="myListenerContainer" connection-factory="connectionFactory">
<rabbit:listener ref="asyncListener" queue-names="amqp.rabbitmq.events.client.connections.created"/>
</rabbit:listener-container>
With the above configuration i am getting exception: Channel shutdown: channel error; protocol method: #method(reply-code=406, reply-text=PRECONDITION_FAILED - inequivalent arg 'internal' for exchange 'amq.rabbitmq.log' in vhost '/': received 'false' but current is 'true', class-id=40, method-id=10)
Not only the amq.rabbitmq.events topic, but pointing other internal topic also yields same exception.
Exception:

There is an internal attribute for you on the :topic-exchange which is false by default.
On the other hand there is auto-declare to try do not declare it at all. Just because that exchange is there on Broker anyway.
