skywalking项目打印traceId

# 1、背景 #

在我们系统或者应用中集成了skywalking后，我就可以进行链路的跟踪了。我们在使用ELK或者其他的一些日志分析工具查找日志。如果要跟踪系统调用链，我们需要在日志中打印出traceId。

# 2、引入依赖 #

<dependency>
        <groupId>org.apache.skywalking</groupId>
        <artifactId>apm-toolkit-logback-1.x</artifactId>
        <version>8.4.0</version>
    </dependency>

# 3、修改logback.xml #

在对应的appender中添加

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

*  Logback中的encoder本身是包含一个layout的，在有此Appender中是可以直接用encoder中的layout部分的。
 *  encoder的class是LayoutWrappingEncoder，不是PatternLayoutEncoder。
 *  使用%tid 来占trace-id的位置，默认TID:N/A，当有请求调用时，会显示trace-id。

修改

*  layout的class采用skywalking中才改的org.apache.skywalking.apm.toolkit.log.logback.v1.x.TraceIdPatternLogbackLayout。
 *  在pattern中添加\[%tid\] tid参数是用来打印traceId的值。

全部logback.xml
