pom.xml 文件添加相关依赖

<dependency>
	<groupId>org.apache.skywalking</groupId>
	<artifactId>apm-toolkit-logback-1.x</artifactId>
	<version>6.6.0</version>
</dependency>

src/main/resources/logback-spring.xml 中添加对应节点

${LOGGING_PATH}，日志路径在系统环境变量设置，Linux 系统在 /etc/profile文件新增用source刷新，统一规划日志输出目录，方便filebeat发送日志给ELK系统。此处不输出console日志，减少服务器不必要性能负担，直接查看文件日志，不用看console日志。

在 appender-->encoder-->pattern 节点添加 tid 输出标识。

启动程序，skywalking-agent 探针，进行数据采集上报

mvn spring-boot:run -Dspring-boot.run.jvmArguments="-javaagent:D:\SkyWalkingAgent\skywalking-agent.jar -Dskywalking.agent.service_name=book-server1" 
mvn spring-boot:run -Dspring-boot.run.jvmArguments="-javaagent:D:\SkyWalkingAgent\skywalking-agent.jar -Dskywalking.agent.service_name=book-server2" 
mvn spring-boot:run -Dspring-boot.run.jvmArguments="-javaagent:D:\SkyWalkingAgent\skywalking-agent.jar -Dskywalking.agent.service_name=book-service1" 
mvn spring-boot:run -Dspring-boot.run.jvmArguments="-javaagent:D:\SkyWalkingAgent\skywalking-agent.jar -Dskywalking.agent.service_name=book-service2" 
mvn spring-boot:run -Dspring-boot.run.jvmArguments="-javaagent:D:\SkyWalkingAgent\skywalking-agent.jar -Dskywalking.agent.service_name=book-gateway1"

也可以打包成jar文件，java -jar方式启动。如图，
