## 1、导入下面的jar ##

## 2、在resource目录下新建log4j.properties文件，文件中的配置表示日志的打印方式和存储方式 ##

### 输出信息到控制抬 ###
    log4j.appender.stdout = org.apache.log4j.ConsoleAppender
    log4j.appender.stdout.Target = System.out
    log4j.appender.stdout.layout = org.apache.log4j.PatternLayout
    log4j.appender.stdout.layout.ConversionPattern = [%-5p] %d{ yyyy-MM-dd HH:mm:ss,SSS} method:%l%n%m%n
    
    ### 输出DEBUG 级别以上的日志到=E://logs/error.log ###
    log4j.appender.D = org.apache.log4j.DailyRollingFileAppender
    log4j.appender.D.File = E://shiro_logs/log.log
    log4j.appender.D.Append = true
    log4j.appender.D.Threshold = DEBUG 
    log4j.appender.D.layout = org.apache.log4j.PatternLayout
    log4j.appender.D.layout.ConversionPattern = %-d{ yyyy-MM-dd HH:mm:ss}  [ %t:%r ] - [ %p ]  %m%n
    
    ### 输出ERROR 级别以上的日志到=E://logs/error.log ###
    log4j.appender.E = org.apache.log4j.DailyRollingFileAppender
    log4j.appender.E.File =E://shiro_logs/error.log 
    log4j.appender.E.Append = true
    log4j.appender.E.Threshold = ERROR 
    log4j.appender.E.layout = org.apache.log4j.PatternLayout
    log4j.appender.E.layout.ConversionPattern = %-d{ yyyy-MM-dd HH:mm:ss}  [ %t:%r ] - [ %p ]  %m%n

## 3、测试 ##

private  static final Logger logger =  LoggerFactory.getLogger(Test.class);
    logger.info("My First Application,{},{}","参数1","参数2");
    。。。
    
    控制台打印结果：
    [INFO ] 2020-06-28 15:47:58,667 method:com.adutec.shiro.Test.main(Test.java:22)
    My First Application,参数1,参数2
    
    生成的文件中显示效果：
    2020-06-28 15:47:58  [ main:0 ] - [ INFO ]  My First Application,参数1,参数2
