Question

我正在使用log4j将日志生成为活动的mq。

当我将日志级别设置为DEBUG，INFO，WARN，ERROR和FATAL时，日志消息将存储到队列中。

但是当设置为TRACE和所有情况时。我正在低于例外。

线程中的异常＆＃34; ActiveMQ InactivityMonitor WriteCheckTimer＆＃34; java.lang.StackOverflowError。 at java.util.GregorianCalendar.computeFields（GregorianCalendar.java:2333）在java.util.GregorianCalendar.computeFields（GregorianCalendar.java:2312） at java.util.Calendar.setTimeInMillis（Calendar.java:1804） at java.util.Calendar.setTime（Calendar.java:1770） at java.text.SimpleDateFormat.format（SimpleDateFormat.java:943） at java.text.SimpleDateFormat.format（SimpleDateFormat.java:936） at java.text.DateFormat.format（DateFormat.java:345）在org.apache.log4j.helpers.PatternParser $ DatePatternConverter.convert（PatternParser.java:443）在org.apache.log4j.helpers.PatternConverter.format（PatternConverter.java:65）在org.apache.log4j.PatternLayout.format（PatternLayout.java:506）在org.apache.log4j.WriterAppender.subAppend（WriterAppender.java:310）在org.apache.log4j.RollingFileAppender.subAppend（RollingFileAppender.java:276）在org.apache.log4j.WriterAppender.append（WriterAppender.java:162）在org.apache.log4j.AppenderSkeleton.doAppend（AppenderSkeleton.java:251）在org.apache.log4j.helpers.AppenderAttachableImpl.appendLoopOnAppenders（AppenderAttachableImpl.java:66）在org.apache.log4j.Category.callAppenders（Category.java:206）在org.apache.log4j.Category.forcedLog（Category.java:391）在org.apache.log4j.Category.log（Category.java:856） at org.slf4j.impl.Log4jLoggerAdapter.trace（Log4jLoggerAdapter.java:154） at org.apache.activemq.util.ClassLoadingAwareObjectInputStream.load（ClassLoadingAwareObjectInputStream.java:128） atorg.apache.activemq.util.ClassLoadingAwareObjectInputStream.resolveClass（ClassLoadingAwareObjectInputStream.java:56） at java.io.ObjectInputStream.readNonProxyDesc（ObjectInputStream.java:1620） at java.io.ObjectInputStream.readClassDesc（ObjectInputStream.java:1521） at java.io.ObjectInputStream.readOrdinaryObject（ObjectInputStream.java:1781） at java.io.ObjectInputStream.readObject0（ObjectInputStream.java:1353） at java.io.ObjectInputStream.readObject（ObjectInputStream.java:373）在org.apache.activemq.command.ActiveMQObjectMessage.getObject（ActiveMQObjectMessage.java:206） at org.apache.activemq.command.ActiveMQObjectMessage.toString（ActiveMQObjectMessage.java:250） at java.lang.String.valueOf（String.java:2994）在java.lang.StringBuilder.append（StringBuilder.java:131）在org.apache.activemq.ActiveMQSession.send（ActiveMQSession.java:1952）在org.apache.activemq.ActiveMQMessageProducer.send（ActiveMQMessageProducer.java:288）在org.apache.activemq.ActiveMQMessageProducer.send（ActiveMQMessageProducer.java:223）在org.apache.activemq.ActiveMQMessageProducerSupport.send（ActiveMQMessageProducerSupport.java:241）在org.apache.activemq.ActiveMQTopicPublisher.publish（ActiveMQTopicPublisher.java:123）。

请帮我理解这个问题，我的代码是：

import java.io.File;
import java.io.IOException;

import org.apache.log4j.ConsoleAppender;
import org.apache.log4j.FileAppender;
import org.apache.log4j.Level;
import org.apache.log4j.Logger;
import org.apache.log4j.PatternLayout;
import org.apache.log4j.RollingFileAppender;
import org.apache.log4j.net.JMSAppender;

public class Example {
    private static Logger log = Logger.getLogger(Example.class);
    public void publishLogs() throws IOException
    {
        log.info("set the level to root logger");
        Logger logger = Logger.getRootLogger();

        logger.setLevel(Level.TRACE);
        PatternLayout layout = new PatternLayout("%d{ISO8601} [%t] %-5p %c %x - %m%n");
        logger.addAppender(new ConsoleAppender(layout));
        logger.setAdditivity(false);
        JMSAppender jmsappender = new JMSAppender();
        jmsappender.setInitialContextFactoryName("org.apache.activemq.jndi.ActiveMQInitialContextFactory");
        jmsappender.setProviderURL("tcp://localhost:61616");
        jmsappender.setTopicConnectionFactoryBindingName("ConnectionFactory");
        jmsappender.setTopicBindingName("dynamicTopics/logtopic1");
        jmsappender.activateOptions();
        logger.addAppender(jmsappender);
    }
    public static void main(String[] args) throws IOException {

        log.info("main method");

        Example ex = new Example();

        log.info("call the publish logs method");
        ex.publishLogs();

    }

}

的log4j.xml：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE log4j:configuration SYSTEM "log4j.dtd">
<log4j:configuration debug="true"
    xmlns:log4j='http://jakarta.apache.org/log4j/'>

    <appender name="file" class="org.apache.log4j.RollingFileAppender">
       <param name="append" value="false" />
       <param name="maxFileSize" value="5MB" />
       <param name="maxBackupIndex" value="5" />
       <!-- For Tomcat -->
       <param name="file" value="D:/logs/myStruts1App.log" />
       <layout class="org.apache.log4j.PatternLayout">
        <param name="ConversionPattern"
            value="%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n" />
       </layout>
    </appender>

    <root>
        <level value="ERROR" />
        <appender-ref ref="file" />
    </root>

</log4j:configuration>
