在我对 JMS Appenders 的研究中,我发现了 turorial1和tutorial2。我试图关注他们,但我无法运行示例程序。
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();
}
}
}
我需要让 Receiver 从项目中收集所有日志,但我什至无法运行这个简单的示例。可能我不知道如何正确配置它,因为我得到了这个输出:
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.
我是否错过了在类路径中添加一些代码行或一些文件?我是 log4j 的新手。
AspectJ
编辑:我在课堂上设置了 Logger 。但我认为也在Receiver
Logger 中创建并发送日志,所以可能应该在 中完成Receiver
,而不是在我的项目中的其他类中。
static final Logger logger = Logger.getLogger(ReportingAspect.class);
@Before("setLoggingFile()")
public void setProperties() {
PropertyConfigurator.configure("log4j.properties");
}
