Spring boot 日志记录-如何删除跟踪日志前缀

1.Message LOG

2.TRACE LOG - message field contains trace information without any actual message.

这些是我的 springboot 应用程序中的应用程序日志。在第一个日志中，有实际的消息，第二个日志只是一个跟踪日志，其中消息内部有跟踪信息。

只要有消息，第一行就可以。但第二行我只想打印消息内的跟踪日志（以 { taceId 开头）。我将在下面发布我的 logback 配置

这是我的logback-spring xml，我想在其中自定义STDOUT模式。在 %message 中，我已经获取了 JSON 格式的跟踪信息，并且“net.logstash.logback.encoder.LoggingEventCompositeJsonEncoder”类正在将 json 转换为 json，此时反斜杠进入消息的每个子字段。
所以这里的要求是删除跟踪消息的前缀，以便它只打印 %message，它是 JSON。
并且还删除 JSON 编码器，这样我就不会在每个子字段中插入这些反斜杠。

我厌倦了删除在编译时给我错误的类，并且还尝试提供核心编码器，这在编译时也给出了 logback 配置错误。

我没有找到一种方法来删除 c.c.s.config.sleuth.LoggingSpanReporter 类生成的日志的所有前缀。

请建议一种方法，以便在 LoggingSpanReporter 有日志行时仅打印跟踪并删除 JSON Encoder 类。我想要的只是 JSON 格式，以便 Kibana 解析为子字段。

    <appender name="TRACE" class="ch.qos.logback.core.ConsoleAppender">
<encoder>
<pattern>%message%n</pattern>
<charset>utf8</charset>
<immediateFlush>true</immediateFlush>
</encoder>
</appender>
<appender name="ASYNC-TRACE" class="ch.qos.logback.classic.AsyncAppender">
<appender-ref ref="TRACE"/>
<!-- do not discard any messages -->
<discardingThreshold>0</discardingThreshold>
<!-- size of the blocking queue -->
<queueSize>500</queueSize>
</appender>
<!--Appends Custom pattern for Trace Logs-->
<logger name="com.cpg.springboot.config.sleuth.LoggingSpanReporter" level="INFO" additivity="false">
<appender-ref ref="ASYNC-TRACE"/>
</logger>

这解决了我的模式问题，Kibana 能够解析 JSON 并映射到字段中。此附加程序的目标是 Sleuth.LoggingSpanReporter 类生成的日志 并应用该模式并仅打印 %message 内的跟踪。
