springboot logback: java.lang.ClassNotFoundException: org.apache.skywalking.apm.toolkit.log.logback.v1.x.TraceIdPatternLogbackLayout

Question

我用的是springboot（版本：2.1.5.RELEASE）创建项目，然后用logback-spring.xml记录日志。

这样的配置：

    <appender name="FILE_ERROR" class="ch.qos.logback.core.rolling.RollingFileAppender">
        <file>${LOG_PATH}/${appName}/${appName}-error.log</file>
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
            <fileNamePattern>${LOG_PATH}/${appName}/${appName}-error-%d{yyyy-MM-dd}.%i.log</fileNamePattern>
            <timeBasedFileNamingAndTriggeringPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP">
                <maxFileSize>200MB</maxFileSize>
            </timeBasedFileNamingAndTriggeringPolicy>
        </rollingPolicy>
        <append>true</append>
        <encoder class="ch.qos.logback.core.encoder.LayoutWrappingEncoder">
            <layout class="org.apache.skywalking.apm.toolkit.log.logback.v1.x.TraceIdPatternLogbackLayout">
                <pattern>${CONSOLE_LOG_PATTERN}</pattern>
            </layout>
        </encoder>
        <filter class="ch.qos.logback.classic.filter.LevelFilter">
            <level>error</level>
            <onMatch>ACCEPT</onMatch>
            <onMismatch>DENY</onMismatch>
        </filter>
    </appender>

但是当我启动我的应用程序时，logback 显示以下错误：

Exception in thread "main" java.lang.IllegalStateException: Logback configuration error detected: 
ERROR in ch.qos.logback.core.joran.action.NestedComplexPropertyIA - Could not create component [layout] of type [org.apache.skywalking.apm.toolkit.log.logback.v1.x.TraceIdPatternLogbackLayout] java.lang.ClassNotFoundException: org.apache.skywalking.apm.toolkit.log.logback.v1.x.TraceIdPatternLogbackLayout
ERROR in ch.qos.logback.core.joran.spi.Interpreter@20:26 - no applicable action for [pattern], current ElementPath  is [[configuration][appender][encoder][layout][pattern]]

丢失了一些用于 logback 的操作（或如何添加它们）？

要使用 apm-toolkit-logback-1.x 中的 TraceIdPatternLogbackLayout，您必须依赖工具包

行家：

<dependency>
    <groupId>org.apache.skywalking</groupId>
    <artifactId>apm-toolkit-logback-1.x</artifactId>
    <version>8.1.0</version>
</dependency>

gradle

compile group: 'org.apache.skywalking', name: 'apm-toolkit-logback-1.x', version: '8.1.0'

springboot logback: java.lang.ClassNotFoundException: org.apache.skywalking.apm.toolkit.log.logback.v1.x.TraceIdPatternLogbackLayout

springboot logback: java.lang.ClassNotFoundException: org.apache.skywalking.apm.toolkit.log.logback.v1.x.TraceIdPatternLogbackLayout
