如何将springboot应用中的日志加上skywalking的traceid

为了能够根据skywalking中的traceId，在kibana中查询到相关日志，需要修改springboot应用中的logback配置文件

由于我们是利用logstash直接打到logstash服务器上的，所以根据官方文档

（https://github.com/apache/skywalking/blob/v8.0.0/docs/en/setup/service-agent/java-agent/Application-toolkit-logback-1.x.md）

这样操作

• Dependency the toolkit, such as using maven or gradle

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

• set LogstashEncoder of logback.xml

  <encoder charset="UTF-8" class="net.logstash.logback.encoder.LogstashEncoder">
  
    <provider class="org.apache.skywalking.apm.toolkit.log.logback.v1.x.logstash.TraceIdJsonProvider">
  
    </provider>
  
  </encoder>

如果你的appender是 ConsoleAppender，则可以这样

• Dependency the toolkit, such as using maven or gradle

  <dependency>
  
    <groupId>org.apache.skywalking</groupId>
    
    <artifactId>apm-toolkit-logback-1.x</artifactId>
    
    <version>{project.release.version}</version>
  
  </dependency>

• set %tid in Pattern section of logback.xml

  <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
  
    <encoder class="ch.qos.logback.core.encoder.LayoutWrappingEncoder">
    
    <layout class="org.apache.skywalking.apm.toolkit.log.logback.v1.x.TraceIdPatternLogbackLayout">
    
    <Pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%tid] [%thread] %-5level %logger{36} -%msg%n</Pattern>
    
    </layout>
    
    </encoder>
  
  </appender>

• with the MDC, set %X{tid} in Pattern section of logback.xml

  <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
  
    <encoder class="ch.qos.logback.core.encoder.LayoutWrappingEncoder">
    
    <layout class="org.apache.skywalking.apm.toolkit.log.logback.v1.x.mdc.TraceIdMDCPatternLogbackLayout">
    
    <Pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%X{tid}] [%thread] %-5level %logger{36} -%msg%n</Pattern>
    
    </layout>
    
    </encoder>
  
  </appender>

这样配置以后我们就可以根据skywalking中的traceId找到相关的请求调用链日志了。
