在有关JMS Appender的调查中，我找到了turorial1和tutorial2。我尝试遵循它们，但是无法运行示例程序。

我首先创建了文件log4j.properties

log4j.rootLogger=INFO, stdout, jms

#
log4j.logger.org.apache.activemq=INFO, stdout

log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d %-5p %c - %m%n

#
log4j.appender.jms=org.apache.log4j.net.JMSAppender
log4j.appender.jms.InitialContextFactoryName=org.apache.activemq.jndi.ActiveMQInitialContextFactory
log4j.appender.jms.ProviderURL=tcp://localhost:61616
log4j.appender.jms.TopicBindingName=logTopic
log4j.appender.jms.TopicConnectionFactoryBindingName=ConnectionFactory

和jndi.properties

topic.logTopic=logTopic

然后我将Receiver.java添加到我的项目中

public class Receiver implements MessageListener {

    public Receiver() throws Exception {
        ActiveMQConnectionFactory factory = new ActiveMQConnectionFactory("tcp://localhost:61616");
        Connection conn = factory.createConnection();
        Session sess = conn.createSession(false, Session.AUTO_ACKNOWLEDGE);
        conn.start();
        MessageConsumer consumer = sess.createConsumer(sess.createTopic("logTopic"));
        consumer.setMessageListener(this);
        Logger log = Logger.getLogger(Receiver.class);

        log.info("Test log");

        Thread.sleep(1000);
        consumer.close();
        sess.close();
        conn.close();
        System.exit(1);
    }

    public static void main(String[] args) throws Exception {
        new Receiver();
    }

    @Override
    public void onMessage(Message message) {
        try {
            // receive log event in your consumer
            LoggingEvent event = (LoggingEvent)((ActiveMQObjectMessage)message).getObject();
            System.out.println("Received log [" + event.getLevel() + "]: "+ event.getMessage());
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

我需要使Receiver收集项目中的所有日志，但是我什至无法运行此简单示例。可能我不知道如何正确配置它，因为我得到了以下输出：

log4j:WARN No appenders could be found for logger (org.apache.activemq.transport.WireFormatNegotiator).
log4j:WARN Please initialize the log4j system properly.
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.

我是否错过了在代码或类文件中添加一些行到类路径？我是log4j的新手。

编辑：我在AspectJ类中设置Logger
。但是我认为在ReceiverLogger中也会创建日志并发送日志，因此可能应该在Receiver而不是在项目的其他类中完成。

static final Logger logger = Logger.getLogger(ReportingAspect.class);

@Before("setLoggingFile()")
public void setProperties() {
    PropertyConfigurator.configure("log4j.properties");
}
