log4j2新objectMessageAsJsonObject问题

Question

我遇到了此配置的问题，我正在尝试确定错误是否来自 json 序列化（使用 lombok 和 jackson）、与库的兼容性或别的东西。 我正在尝试在 message 字段中使用 log4j2 将自定义对象编写为 json，我读到 objectMessageAsJsonObject 会帮助我，这是我的 logj2.xml

<Configuration status="INFO">
    <Appenders>
        <Console name="Console" target="SYSTEM_OUT">
            <JSONLayout properties="true" compact="true" eventEol="true" objectMessageAsJsonObject="true">
                <KeyValuePair key="guid" value="${ctx:guid}"/>
                <KeyValuePair key="ip" value="${ctx:x-forwarded-for}"/>
                <KeyValuePair key="user-agent" value="${ctx:user-agent}"/>
                <KeyValuePair key="host" value="${ctx:host}"/>
            </JSONLayout>
        </Console>
    </Appenders>
    <Loggers>
        <Logger name="com" level="debug">
            <AppenderRef ref="Console"/>
        </Logger>
        <Root level="info">
            <AppenderRef ref="Console"/>
        </Root>
    </Loggers>
</Configuration>

这是我的自定义对象

@Builder
@AllArgsConstructor
public class EventLog {

  private String service;
  private String method;
  private String event;
  private String eventType;
  private String level;
  private Object information;
  private Long elapsedTime;
  private String sessionId;
  private String identification;
  private String code;
  private String message;
}

我的 pom 依赖项

我得到的结果

预期结果

我试图写日志的方式是方法的一个方面。

@Around("@annotation(loggable)")
  public Object logMethodEntryExit(ProceedingJoinPoint pjp, Loggable loggable) throws Throwable {
    long start = System.currentTimeMillis();
    String className = pjp.getSignature().getDeclaringTypeName();
    String methodName = pjp.getSignature().getName();
    Object information = pjp.getArgs();
    log.debug(EventLog.builder()
        .method(methodName)
        .service(className)
        .elapsedTime(start)
        .information(information)
        .eventType(REQUEST.name())
        .level(loggable.level().name())
        .build());

    Mono<Object> result = (Mono<Object>) pjp.proceed();
    long elapsedTime = System.currentTimeMillis() - start;
    return result.doOnNext(element -> log.debug(EventLog.builder()
        .method(methodName)
        .service(className)
        .elapsedTime(elapsedTime)
        .information(element)
        .eventType(RESPONSE.name())
        .level(loggable.level().name())
        .build()));
  }

而且 json 从未显示，请对此有所帮助

在类似的设置中遇到了类似的问题 - 将 org.springframework.cloud 降级到 Hoxton.SR6（和 org.springframework.boot 到 2.3.0.RELEASE）解决了它。
