Question

我有一个SpringBoot应用程序，我正在尝试实现log4j2的JMS Appender。该应用程序似乎找到了附加程序，但随后出现错误：

"JMS message Producer Not Available"

我已经声明了返回类型为org.apache.activemq.ActiveMQConnectionFactory的bean，并在log4j2.xml中定义了附加程序和记录器（记录器在RollingFile和Console上工作正常）。

我不确定如何解决此问题，在Google上找不到很多。

感谢任何指针。

log4j2.xml附加程序条目

   <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>

我的豆子：

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");
  }

}

Answer 1

正如Log4j documentation所阐明的那样，JMS附加程序配置中的factoryBindingName确实不是指的是Spring bean。它是指连接工厂绑定所在的JNDI名称。

尝试使用如下配置：

<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>

要清楚，ActiveMQ InitialContextFactory实现仅在客户端，这意味着它实际上并没有通过网络连接来“查找”远程服务器上的资源。相反，通常在InitialContext的“环境”属性中配置所有资源。但是，有一个默认的JMS连接工厂，默认情况下绑定到ConnectionFactory，如果您不想或不能专门配置它，可以在任何队列名称上使用dynamicQueues/前缀。为了方便和简单起见，我建议您使用这些默认资源。

Answer 2

基于ActiveMQ文档（访问https://activemq.apache.org/how-do-i-use-log4j-jms-appender-with-activemq），您必须创建新文件： jndi.properties 。然后添加一行：

queue.logQueue=myQueueToLogEvents

注意，

logQueue

是您的 log4j2.xml 文件中的名称，并且

myQueueToLogEvents

是目标队列的名称。最后，消息将发送到 myQueueToLogEvents 队列。希望对您有所帮助。
