1：添加依赖

<dependency>
 <groupId>org.slf4j</groupId>
 <artifactId>slf4j-log4j12</artifactId>
 <version>1.7.25</version>
</dependency>

<dependency>
 <groupId>org.apache.flume.flume-ng-clients</groupId>
 <artifactId>flume-ng-log4jappender</artifactId>
 <version>1.7.0</version>
</dependency>

2：排除spring自带logging

<!-- 不引入默认的日志 -->
<exclusions>
   <exclusion>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-starter-logging</artifactId>
   </exclusion>
</exclusions>

3：配置log4j.properties

log4j.rootLogger=INFO,GetLogger,stdout

log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.target=System.out
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %p [%c:%L] - %m%n

log4j.logger.GetLogger=INFO,GetLogger
log4j.appender.GetLogger=org.apache.log4j.DailyRollingFileAppender
log4j.appender.GetLogger.layout=org.apache.log4j.PatternLayout
log4j.appender.GetLogger.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %p [%c:%L] - %m%n
log4j.appender.GetLogger.Append=true

log4j.logger.flume = INFO,flume
log4j.appender.flume = org.apache.flume.clients.log4jappender.Log4jAppender
log4j.appender.flume.Threshold=INFO
log4j.appender.flume.Hostname = xxxxxxxx
log4j.appender.flume.Port = 44444
log4j.appender.flume.UnsafeMode = true
