Mybatis、maven項目中整合log4j (17)

Mybatis、maven項目總整合log4j 

java 中Mybatis、maven項目總整合log4j 

1、pom增加log4j包引用

 

 2、添加 log4j.properties文件

# java中在maven項目增加log4j日誌支援
#log4j.rootLogger=CONSOLE,FILE
log4j.rootLogger=DEBUG,CONSOLE,FILE
#應用於控制台
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
#每天新建日誌
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
#應用於文件
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增加日誌支援

 

 4、執行(16)例子應用,在控制台列印日誌通知在本地磁碟建立文件夾同時寫入日誌

4.2 控制台日誌

A、文件目錄

  

 

B、file.log 文件內容(文件內容和控制台列印日誌相同)

  

 

 總結:日誌添加說明

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

2、開啟日誌 (mybatis-03.xml 中開啟日誌)

3、如果不指定,mybatis就會根據以下順序尋找日誌

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

4、編寫日誌輸出文件:log4j.properties 日誌級別:DEBUG<INFO<WARN<ERROR
