Java reactor.netty.http.server.AccessLog生成LoggingEvent而不是AccessEvent

我一直在尝试用webflux配置SpringBoot2.1，以便将访问日志存储在JSON中。此外，我需要将协议、状态代码等信息作为单独的JSON字段（不是消息的一部分）。看看我在网上找到的。它似乎有我需要的一切。但在运行时，我得到以下错误：

我的配置相当简单：

<appender name="accessLog" class="ch.qos.logback.core.FileAppender">
    <file>${LOGS}/access_log.log</file>
    <encoder class="net.logstash.logback.encoder.LogstashAccessEncoder"/>
</appender>

<logger name="reactor.netty.http.server.AccessLog" level="DEBUG" additivity="false">
    <appender-ref ref="accessLog"/>
</logger>

${LOGS}/access_log.log

---

在这一点上，我被卡住了。我一直在互联网上搜索并查看logback代码，但我仍然不知道如何让AccessEvent包含更多信息，而不是LoggingEvent，logstash logback encoder中的

LogstashAccessEncoder

提供AccessEvents。只有jetty和tomcat可以使用logback访问。它不适用于反应堆netty

Reactor netty的

Reactor.netty.http.server.AccessLog

只使用标准日志事件（而不是AccessEvent）。因此，如果您想使用logstash logback编码器，您将使用

LogstasEncoder

而不是

LogstasAccessEncoder

，如下所示：

解析reactor.netty.http.server.AccessLog中的日志消息，并将其拆分为单独的JSON字段
