使用Log4j扩展发送消息报错。

log4j.properties

Logtest.java

public class Logtest {
     static final Log log = LogFactory.getLog("testLog");

     public void printLog(){
        log.info("just a test");
     }

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

因为看了这里的配置有误：
https://github.com/killme2008/Metamorphosis/wiki/%E4%BD%BF%E7%94%A8Log4j%E6%89%A9%E5%B1%95%E5%8F%91%E9%80%81%E6%B6%88%E6%81%AF

找到原因了，改成下边的配置就好了

log4j.properties

log4j.logger.testLog=info, testMessage
log4j.additivity.testMessage=false
log4j.appender.testMessage=com.taobao.metamorphosis.client.extension.log4j.DailyRollingFileStreamAppender
log4j.appender.testMessage.topic=msg
log4j.appender.testMessage.zkConnect=192.168.111.140:2181
log4j.appender.testMessage.BufferedIO=true
log4j.appender.testMessage.DatePattern='.'yyyy-MM-dd_HH
log4j.appender.testMessage.File=../../logs/test.log
log4j.appender.testMessage.layout=org.apache.log4j.PatternLayout
log4j.appender.testMessage.layout.ConversionPattern=%d{MM-dd HH:mm:ss} - %m%n
log4j.appender.testMessage.Append=true
