1. 添加maven依赖

注意scala版本

<!-- log4j-api-scala -->
<dependency>
	<groupId>org.apache.logging.log4j</groupId>
	<artifactId>log4j-api-scala_2.11</artifactId>
	<version>11.0</version>
</dependency>
<!-- log4j-core -->
<dependency>
    <groupId>org.apache.logging.log4j</groupId>
	<artifactId>log4j-core</artifactId>
	<version>2.8.2</version>
</dependency>
<!-- log4j-api -->
<dependency>
	<groupId>org.apache.logging.log4j</groupId>
	<artifactId>log4j-api</artifactId>
	<version>2.8.2</version>
</dependency>

2. 在src目录下添加log4j.properties文件

log4j.rootLogger=INFO,stdout
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.logfile=org.apache.log4j.FileAppender
log4j.appender.logfile.File=target/spring.log
log4j.appender.logfile.layout=org.apache.log4j.PatternLayout
log4j.appender.logfile.layout.ConversionPattern=%d %p [%c] - %m%n

3.代码中使用

@transient lazy val log = Logger.getLogger(this.getClass)
log.info("hello scala log4j")
