Alla Gofman updated LOG4J2-2873:
--------------------------------
Description:
I create LogEvent where message is of type MapMessage (key-value pairs).
I send this log even to SocketAppender by JsonLayout.
The json created :
{quote}{"instant":\{"epochSecond":1592431380,"nanoOfSecond":11953900},"thread":"MetricsScheduler-1","level":"alert","loggerName":"com.bmc.ctm.saas.alerts.AlertsLogger","message":"alertmsg=\"MFT
Server isn't responding!\" component=\"mft-server\" id=\"DRAFT_101\"
key1=\"value1\"","endOfBatch":false,"loggerFqcn":"com.bmc.ctm.saas.alerts.AlertsLoggerWrapper","contextMap":{},"threadId":18,"threadPriority":5}{quote}
I tried also setObjectMessageAsJsonObject(true) - same result.
On ServerSocket side I want to parse/deserialize this json string to LogEvent
and log it to File Appender:
{quote}{{PatternLayout. JSONObject jobj = new JSONObject(line);}}
{{LogEvent logEvent = new JsonLogEventParser().parseFrom(line);}}
{quote}
Then parseFrom() build the LogEvent, message object create of type
SimpleMessage and not MapMessage. Then it comes to resolving *%map* pattern in
MapPatternConverter.format() - do nothing and return.
{quote}public void format(final LogEvent event, final StringBuilder toAppendTo)
Unknown macro: \{ MapMessage msg; if (event.getMessage() instanceof
MapMessage) Unknown macro}
else
Unknown macro: \{ return; }
{quote}
