变更的目的是什么
支持MDC，方便用户接入链路追踪系统也可以在logback.xml中json格式化日志。
简短的更新日志
pom.xml文件中引入logstash-logback-encoder.jar包
验证这一变化
<encoder charset="utf-8" class="net.logstash.logback.encoder.LogstashEncoder"> <includeCallerData>true</includeCallerData> <includeMdcKeyName>springAppName</includeMdcKeyName> <includeMdcKeyName>traceId</includeMdcKeyName> <includeMdcKeyName>spanId</includeMdcKeyName> <includeMdcKeyName>parentSpanId</includeMdcKeyName> <customFields>{"system": "know-streaming"} </customFields> </encoder>在logback-spring.xml中加入以上encoder后即可支持链路追踪功能。
jar包兼容性及功能已测试通过。
