        <version>1.2.17</version>
    </dependency>
    
    
    2.添加文件:再resources/log4j.properties
    
    log4j.rootLogger=DEBUG,console,file

    #控制台输出的相关设置
    log4j.appender.console = org.apache.log4j.ConsoleAppender
    log4j.appender.console.Target = System.out
    log4j.appender.console.Threshold=DEBUG
    log4j.appender.console.layout = org.apache.log4j.PatternLayout
    #log4j.appender.console.layout.ConversionPattern=[%c]-%m%n
    log4j.appender.console.layout.ConversionPattern=%5p [%t] - %m%n
    
    #文件输出的相关设置
    log4j.appender.file = org.apache.log4j.RollingFileAppender
    log4j.appender.file.File=./log/rzk.log
    log4j.appender.file.MaxFileSize=10mb
    log4j.appender.file.Threshold=DEBUG
    log4j.appender.file.layout=org.apache.log4j.PatternLayout
