Is there a way to set JSON object to elasticsearch index as key-value pairs via AsyncLogger using log4j2-elasticsearch-hc appender
问题
我正在使用log4j2-elasticsearch-hc appender（asyncLogger）将日志直接写入ElasticSearch。我的日志基本上是Log POJO（即JSON）。然而，当我使用Logger.info(logPojoInstance)时，整个实例会被字符串化为一个名为"message"的属性，而不是键值对。请查看下面的屏幕截图中的ElasticSearch输出：
如何才能以键值对的形式显示LogDTO，而不是以字符串化/序列化的JSON形式显示在message旁边...在这种情况下，我希望能够查询这些日志，但目前不可能。
我尝试了VirtualProperty的方法，但由于我正在使用AsyncLogger，似乎无法设置值。
如果有任何线索，请告诉我！
同时，附上log4j2.xml供参考：

I am using the Using log4j2-elasticsearch-hc appender (asyncLogger) to directly write my logs to ElasticSearch. My log is basically Log POJO (i.e. JSON). However; when I say; Logger.info(logPojoInstance); the entire instance gets stringified against a property named "message" as opposed to being key-value pairs. Please look at the ElasticSearch output in the screenshot below :
What can be done so that the LogDTO is displayed in key-value as opposed to a stringified / serialized json adjacent to message....I want to be able to query these logs which wont be possible in this scenario.
I tried the VirtualProperty approach but as I am using AsyncLogger the value does not seem to set.
<VirtualProperty name="ctxVariable" value="$${ctx:myFavouriteVariable:-notSupportedWithAsyncLogger}" dynamic="true" />
Any leads please let me know !

你可以使用官方的JSON模板布局与log4j2-elasticsearch-hc结合使用。JTL是最丰富和可定制的基于JSON的布局，可以呈现非String类型的消息。有关详细信息，请参阅消息事件模板解析器文档。
英文:
You can use the official JSON Template Layout in combination with log4j2-elasticsearch-hc. JTL is the most feature-rich and customizable JSON-based layout in the wild and can render non-String messages. See the message event template resolver docs for details.
