添加log4j日志系统->resources->log4j.properties
##设置日志记录到控制台的方式
log4j.appender.std=org.apache.log4j.ConsoleAppender
log4j.appender.std.Target=System.err
log4j.appender.std.layout=org.apache.log4j.PatternLayout
log4j.appender.std.layout.ConversionPattern=%d{yyyy-MM-ddHH:mm:ss}%5p%c{1}:%L-%m%n
##设置日志记录到文件的方式
log4j.appender.file=org.apache.log4j.FileAppender
log4j.appender.file.File=mylog.txt
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern=%d{ABSOLUTE}%5p%c{1}:%L-%m%n
##日志输出的级别，以及配置记录方案 debug级别 std控制台输出 file文件输出
log4j.rootLogger=debug,std,file
##级别:error > warn > info>debug>trace
##如果设置了某个级别, 只会打印比这个级别高的或者等于这个级别的日志配置文件->resources->springmvc.xml
