Output time stamp for humans with JSON Layout of log4j2

If you use JSONLayout of log4j2, the output date and time will be output in epoch seconds.

log.json


{
	"instant": {
		"epochSecond": 1563403242,
		"nanoOfSecond": 895000000
	}
}

Since it is difficult to read the epoch seconds directly like a human being, I would like to output the date normally.

So do this.

log4j2.xml


<JsonLayout>
	<!--Abbreviation-->
	<KeyValuePair key="timestamp" value="$${date:yyyy-MM-dd'T'HH:mm:ss,SSSXXX}"/>
</JsonLayout>

result

log.json


{
	"timestamp": "2019-07-18T07:40:42,895+09:00"
}
