SpringBoot学习笔记(2)-配置log4j日志

目录

一、修改build.gradle

首先排除默认日志

然后添加log4j依赖

二、添加log4j.properties

由于SpringBoot的默认日志是Logback，但是许多学过SSM框架的朋友都习惯用log4j，因为这是MyBatis的默认日志，所以这一篇讲解在gradle下如何为SpringBoot配置log4j日志

一、修改build.gradle

首先排除默认日志

configurations {
	//remove default logger
	all*.exclude group: 'org.springframework.boot', module: 'spring-boot-starter-logging'
}

然后添加log4j依赖

// log4j2
	compile ("org.springframework.boot:spring-boot-starter-web") {
		exclude module: 'org.springframework.boot:spring-boot-starter-logging'
	}
	compile ('org.springframework.boot:spring-boot-starter-log4j2')

二、添加log4j2.properties

# Configure logging for testing: optionally with log file
log4j.rootLogger=debug, stdout,D,E
# log4j.rootLogger=WARN, stdout, logfile

log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d %p [%c] - %m%n

log4j.appender.D = org.apache.log4j.DailyRollingFileAppender  
log4j.appender.D.File = C://logs/e3-manager-service-debug.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  

log4j.appender.E = org.apache.log4j.DailyRollingFileAppender  
log4j.appender.E.File =C://logs/e3-manager-service-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

log4j配置细节可以参考其他博客

配置完成后，运行SpringBoot出现以下熟悉的信息，表明项目已经换成了log4j日志了
