Spring Boot 日志配置

1.移除默认日志

<exclusions>
	<exclusion>
		<groupId>org.springframework.boot</groupId>
		<artifactId>spring-boot-starter-logging</artifactId>
	</exclusion>
</exclusions> 

2.添加日志框架依赖

<!--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.创建 log4j.properties 并且放到资源文件目录 src/main/resources

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=%-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=/workspaces/logs/mylog.log
