log4j:WARN No appenders could be found for logger (org.apache.zookeeper.ZooKeeper). log4j:WARN Please initialize the log4j system properly.解决办法

拷贝log4j.properties文件到项目根目录

需要在项目的 src/main/resources 目录下，新建一个文件，命名为“log4j.properties”，在
文件中填入。

log4j.rootLogger=INFO, stdout 
log4j.appender.stdout=org.apache.log4j.ConsoleAppender 
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout 
log4j.appender.stdout.layout.ConversionPattern=%d %p [%c] 
- %m%n 
log4j.appender.logfile=org.apache.log4j.FileAppender 
log4j.appender.logfile.File=target/spring.log 
log4j.appender.logfile.layout=org.apache.log4j.PatternLayout 
log4j.appender.logfile.layout.ConversionPattern=%d %p [%c] 
- %m%n 

在使用log4j的时候，总是会出现如下提示：

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

在网上找了很长时间的答案，最后才发现，是文件的名称写错了；文件名称应该是log4j.properties，然后是写成了log4j.properties.properties，就出现了哪个报错问题，该了名称之后，就好了
