What dependency do I need to use AmqpAppender for log4j?

Question

In my log4j.properties I have the following line:

log4j.appender.queue=org.springframework.amqp.log4j.AmqpAppender

In my pom.xml I have the following spring related inclusions:

<!-- Spring dependencies -->
<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-core</artifactId>
    <version>${spring.version}</version>
    <exclusions>
        <exclusion>
            <groupId>commons-logging</groupId>
            <artifactId>commons-logging</artifactId>

</dependency>
<dependency>
    <groupId>org.springframework.amqp</groupId>
    <artifactId>spring-rabbit</artifactId>
    <version>1.2.0.RELEASE</version>
</dependency>

When I startup the application, I see the following exception:

log4j:ERROR Could not instantiate class [org.springframework.amqp.log4j.AmqpAppender].
java.lang.ClassNotFoundException: org.springframework.amqp.log4j.AmqpAppender  
...

What dependency do I require to make use of org.springframework.amqp.log4j.AmqpAppender ?

Answer 1

You have correct dependency, but class is different a bit:

org.springframework.amqp.rabbit.log4j.AmqpAppender

Pay attention to the package, please.

Answer 2

Not sure I think the appender you found is a different one. There is one appender in:

<dependency>
    <groupId>org.springframework.amqp</groupId>
    <artifactId>spring-amqp</artifactId>
    <version>1.3.6.RELEASE</version>
</dependency>

from spring-ampq .

The spring version maybe different too.
