Create a file named log4j.properties on the directory target/classes/, then copy following content into this file:

log4j.appender.Cons=org.apache.log4j.ConsoleAppender
log4j.appender.Cons.layout=org.apache.log4j.PatternLayout
log4j.appender.Cons.layout.ConversionPattern=%-4r [%t] %-5p %c %x - %m%n

# Root logger set to DEBUG using the A2 appender defined above.
log4j.rootLogger=info, Cons
log4j.additivity=false

#Application Logger+
log4j.logger.com.imooc.mvcdemo=debug, Cons
log4j.logger.org.springframework=debug, Cons
log4j.additivity.com=false
