1.除去springboot自带的日志
1.12 springboot 整合log4j打印日志,java架构笔记,spring boot,log4j,后端

<dependency>
	<groupId>org.springframework.boot</groupId>
	<artifactId>spring-boot-starter</artifactId>
	<exclusions>
		<!-- 除去springboot自带的日志 -->
		<exclusion>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter-logging</artifactId>
		</exclusion>
	</exclusions>
</dependency>

2.添加log4j依赖

<!--引入日志依赖 抽象层 与 实现层-->
<dependency>
	<groupId>org.slf4j</groupId>
	<artifactId>slf4j-api</artifactId>
	<version>1.7.21</version>
</dependency>
<dependency>
	<groupId>org.slf4j</groupId>
	<artifactId>slf4j-log4j12</artifactId>
	<version>1.7.21</version>
</dependency>

3. 添加log4j依赖对应的配置文件log4j.properties[api模块下的resources文件夹下创建]

log4j.rootLogger=DEBUG,stdout,file
log4j.additivity.org.apache=true

log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.threshold=INFO
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n

log4j.appender.file=org.apache.log4j.DailyRollingFileAppender
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.DatePattern='.'yyyy-MM-dd-HH-mm
log4j.appender.file.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n
log4j.appender.file.Threshold=INFO
log4j.appender.file.append=true
log4j.appender.file.File=E:\\logs\\one-pro\\one-pro.log
