在学习zookeeper时候遇见了log4j错误No appenders could be found for logger

log4j:WARN No appenders could be found for logger (org.apache.zookeeper.ZooKeeper). log4j:WARN Please initialize the log4j system properly. log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info. WatchedEvent state:SyncConnected type:None path:null

BUILD SUCCESSFUL (total time: 1 minute 0 seconds)

解决方法是把log3j.properties文件粘贴在项目src目录下,一定要在src目录下,否则会出现同样的错误,下面是配置好后的控制台日志信息
