解决

    1.pom文件添加
    
    <dependency>
        <groupId>log4j</groupId>
        <artifactId>log4j</artifactId>
        <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
    log4j.appender.file.layout.ConversionPattern=[%p][%d{yy-MM-dd}][%c]%m%n
    
    #日志输出级别
    log4j.logger.org.mybatis=DEBUG
    log4j.logger.java.sql=DEBUG
    log4j.logger.java.sql.Statement=DEBUG
    log4j.logger.java.sql.ResultSet=DEBUG
