 2、添加 log4j.PRoPErties文件

# java中在maven项目增加log4j日志支持
#log4j.rootLogger=CONSOLE,FILE
log4j.rootLogger=DEBUG,CONSOLE,FILE
#应用于控制台
log4j.appender.CONSOLE=org.apache.log4j.ConsoleAppender
log4j.appender.CONSOLE.Threshold=DEBUG
#log4j.appender.CONSOLE.Threshold=INFO
log4j.appender.CONSOLE.Target=System.out
log4j.appender.CONSOLE.Encoding=GBK
log4j.appender.CONSOLE.layout=org.apache.log4j.PatternLayout
log4j.appender.CONSOLE.layout.ConversionPattern=[lsjSso]%d-%c-%-4r[%t]%-5p%c%x-%m%n
#每天新建日志
log4j.appender.A1=org.apache.log4j.DailyRollingFileAppender
log4j.appender.A1.File=D:/logs/jackLog
log4j.appender.A1.Encoding=GBK
log4j.appender.A1.Threshold=DEBUG
log4j.appender.A1.DatePattern='.'yyyy-MM-dd
log4j.appender.A1.layout=org.apache.log4j.PatternLayout
log4j.appender.A1.layout.ConversionPattern=%d{ABSOLUTE}%5p%c{1}:%L:%m%n
#应用于文件
log4j.appender.FILE=org.apache.log4j.FileAppender
log4j.appender.FILE.File=D:/logs/jackLog/file.log
log4j.appender.FILE.Append=false
log4j.appender.FILE.Encoding=GBK
log4j.appender.FILE.layout=org.apache.log4j.PatternLayout
log4j.appender.FILE.layout.ConversionPattern=[lsjSso]%d-%c-%-4r[%t]%-5p%c%x-%m%n

 3、pom增加日志支持

4.2 控制台日志

A、文件目录

  

Mybatis、maven项目中整合log4j （17）

 

B、file.log 文件内容(文件内容和控制台打印日志相同)

  

Mybatis、maven项目中整合log4j （17）

 

 总结：日志添加说明

1、log4j，添加log4j的jar包（既：在mybatis-03.xml中引用了jar包）

2、开启日志 （mybatis-03.xml 中开启日志）

3、如果不指定，mybatis就会根据以下顺序寻找日志

      SLF4J-> Apache Commons Logging ---> Log4j 2 ----->Log4j---->JDK logging 

4、编写日志输出文件:log4j.properties 日志级别：DEBUG<INFO<WARN<ERROR
