springboot+druid报错log4j:WARN No appenders could be found for logger (druid.sql.Connection). log4j:WARN Please initialize the log4j system properly.

 

 解决方案：新建文件log4j.properties

log4j.rootLogger=DEBUG, stdout
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%5p [%t] - %m%n 

 效果图:
