log4j:WARN No appenders could be found for logger (org.springframework.core.env.StandardEnvironment)

今天学习spring，运行后出现这么一段：

网上查了一下：这个并不是运行错误,而是log4j没有输出日志产生的警告

解决办法：在src文件夹下建立一个名为log4.properties的文件即可；

文件内容如下：

log4j.rootLogger=DEBUG , stdout
log4j.logger.org.mybatis=DEBUG
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout

log4j.appender.stdout.layout.ConversionPattern=%5p %d %C: %m%n

再次运行程序，输出log4j日志，无警告信息。
