SpringBoot Log4j2 JMS Appender -> “JMS message Producer Not Available”

问题

I have a SpringBoot App I am trying to implement log4j2's JMS Appender. The app seems to find the appender but then I get an error:

JMS message Producer Not Available

I have declared a bean of return type org.apache.activemq.ActiveMQConnectionFactory and defined the appender and logger in my log4j2.xml (the logger works fine to a RollingFile and Console).

I am unsure how to resolve this and can't find much on Google.

log4j2.xml appender entry:

<JMS name="jmsQueue" 
     destinationBindingName="logQueue"
     factoryBindingName="com.mydomain.developer.myappname.ActiveMQ.MyQueueConnectionFactory"
     factoryName="org.apache.activemq.jndi.ActiveMQInitialContextFactory"
     providerURL="tcp://localhost:61616"
     userName="admin"
     password="admin" >
    <JsonLayout properties="true"/>
</JMS>

My Bean:

package com.mydomain.developer.myappname.ActiveMQ

import org.apache.activemq.ActiveMQConnectionFactory;
import org.springframework.context.annotation.Bean;
import org.springframework.stereotype.Component;

@Component
public class MyQueueConnectionFactory{

    @Bean
    public ActiveMQConnectionFactory loggingConnectionFactory(){
        return new ActiveMQConnectionFactory("admin","admin","tcp://localhost:61616");
    }
}

回答1:

As the Log4j documentation makes clear, the factoryBindingName in the JMS appender configuration does not refer to a Spring bean. It refers to a JNDI name where the connection factory is bound.

Try using a configuration like this:

<JMS name="jmsQueue" 
     destinationBindingName="dynamicQueues/logQueue"
     factoryBindingName="ConnectionFactory"
     factoryName="org.apache.activemq.jndi.ActiveMQInitialContextFactory"
     providerURL="tcp://localhost:61616"
     userName="admin"
     password="admin">
    <JsonLayout properties="true"/>
</JMS>

To be clear, the ActiveMQ InitialContextFactory implementation is client-side only meaning it doesn't actually connect across the network to "look up" resources on a remote server. Instead all the resources are typically configured in the "environment" properties of the InitialContext. However, there is a default JMS connection factory bound by default to ConnectionFactory and the dynamicQueues/ prefix can be used on any queue name if you don't want to or can't specifically configure it. I recommend you use these default resources for convenience and simplicity.

Based on ActiveMQ documentation (Visit https://activemq.apache.org/how-do-i-use-log4j-jms-appender-with-activemq) you must create new file: jndi.properties. Then add one line:
