在pax日志记录中，有什么诀窍可以让它起作用吗？如果适用，我可以使用
\$\\{ctx:key\}
从MDC访问值，因此我假设语法类似。我还尝试过在模式中使用查找来查找RoutingAppender、FileAppender等，但没有效果

提前谢谢

编辑：我使用的是最新版本的pax logging api和pax-logging-log4j2（1.11.3）

好的，这还不是一个确定的答案-简单的注释太短，无法描述发生了什么

org.ops4j.pax.logging.log4jv2.Log4jv2Logger.logMessage（）
是日志外观和日志后端之间的桥梁

请记住，使用pax日志，您可以（比如）将Commons日志facade与Log4J1后端一起使用，或将Log4j2 facade（这就是您正在做的）与Logback后端一起使用

这就是为什么
org.ops4j.pax.logging.log4jv2.Log4jv2Logger.logMessage（）
执行以下操作：

} else if (level.intLevel() >= Level.INFO.intLevel()) {
    m_delegate.inform(paxMarker, message.getFormattedMessage(), t, fqcn);
您的结构化消息将更改为字符串
事件[1 testKey=“testValue”]消息

只有配置好的appender才会被调用，而具有提取结构化数据布局的appender无法找到它，因为结构化消息已经转换为普通字符串

这三条线：

  at org.ops4j.pax.logging.log4j2.internal.PaxLoggerImpl.inform(PaxLoggerImpl.java:233)
  at org.ops4j.pax.logging.internal.TrackingLogger.inform(TrackingLogger.java:209)
  at org.ops4j.pax.logging.log4jv2.Log4jv2Logger.logMessage(Log4jv2Logger.java:162)
从pax logging api（facade）通过
TrackingLogger
（bridge）到pax-logging-log4j2（后端）进行交叉，在这两者之间丢失结构化信息

我已经创造了，希望很快能做点什么

编辑1

关键是在
org.apache.logging.log4j.core.lookup.structuredatalookup（）
中，此条件为真：

if (event == null || !(event.getMessage() instanceof StructuredDataMessage)) {
    return null;
}
编辑2

我刚刚修复了，此测试证明它是有效的：

Logger logger = LogManager.getLogger("my.logger");

logger.info(new StructuredDataMessage("1", "hello!", "typeX").with("key1", "sd1"));
logger.info(new StringMapMessage().with("key1", "map1"));

List<String> lines = readLines();
assertTrue(lines.contains("my.logger/org.ops4j.pax.logging.it.Log4J2MessagesIntegrationTest typeX/sd1 [INFO] typeX [1 key1=\"sd1\"] hello!"));
assertTrue(lines.contains("my.logger/org.ops4j.pax.logging.it.Log4J2MessagesIntegrationTest ${sd:type}/map1 [INFO] key1=\"map1\""));
（如果通过Karaf中的
etc/org.ops4j.pax.logging.cfg
进行配置，则必须使用您使用的转义序列）。

请写下您使用的pax日志版本，我将尝试复制。@GrzegorzGrzybek谢谢！我使用的是1.11.3版。
