amqp appender and log4j2 - amqp

Question

I am trying to use amqpappender from spring amqp project in our project
See here:
http://docs.spring.io/spring-amqp/api/org/springframework/amqp/rabbit/log4j/AmqpAppender.html
But we are currently using log4j2 which I do not think amqp appender supports.
Does anyone know if amqp appender works with log4j2?

Answer 1

You can use Spring AMQP v.1.6.0.M1 (or hight) and log4j2 xml configuration.
Appender example:
<RabbitMQ name="rabbitmq"
host="localhost" port="5672" user="guest" password="guest" virtualHost="/"
exchange="log4j2Test" exchangeType="fanout" declareExchange="true" durable="true" autoDelete="false"
applicationId="testAppId" routingKeyPattern="%X{applicationId}.%c.%p"
contentType="text/plain" contentEncoding="UTF-8" generateId="true" deliveryMode="NON_PERSISTENT"
charset="UTF-8"
senderPoolSize="3" maxSenderRetries="5">
</RabbitMQ>

Answer 2

As #Illiahat pointed out, you have to use the latest (unreleased yet) version, such as 1.6.0.M2. The current version (1.5.5) does not support log4j2, that's why you'd get a RabbitMQ is not recognizable message (it cannot use the AppenderSkeleton class).
Here's a gradle configuration example that will get the logger working:
repositories {
mavenCentral()
maven {
url 'https://repo.spring.io/libs-milestone'
}
}
dependencies {
testCompile group: 'junit', name: 'junit', version: '4.11'
compile group: 'org.apache.logging.log4j', name: 'log4j-api', version: '2.5'
compile group: 'org.apache.logging.log4j', name: 'log4j-core', version: '2.5'
compile 'org.springframework.amqp:spring-rabbit:1.6.0.M2'
}
For the logger, you can use the configuration from #Illiahat.

If you are using Log4j 2, you should be able to go through an AMQP JMS provider.
For example, Apache Qpid JMS is a complete AMQP 1.0 Java Message Service 1.1 client built using Qpid Proton.
Qpid also provides an alternate JMS client supporting earlier AMQP versions.
