[jira] [Updated] (LOG4J2-2873) Failed to parse json string to
LogEvent when massage type is MapMessage
[ https://issues.apache.org/jira/browse/LOG4J2-2873?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Alla Gofman updated LOG4J2-2873:
--------------------------------
Component/s: Core
Affects Version/s: 2.13.2
2.13.3
Description:
I create LogEvent where message is of MapMessage type (key-value pairs).
I send this log even to SocketAppender by JsonLayout. (I tried 2 options with setObjectMessageAsJsonObject true and false)
The Json created:
{quote}Unknown macro: \{"instant"}
,"thread":"MetricsScheduler-7","level":"alert","loggerName":"AlertsLogger","message":"\{key1=value1, component=mft-server, id=DRAFT_101, alertmsg=MFT Server isn't responding!}","endOfBatch":false,"loggerFqcn":"com.*.*.saas.alerts.AlertsLoggerWrapper","contextMap":{},"threadId":26,"threadPriority":5}
{quote}
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) {
MapMessage msg;
if (event.getMessage() instanceof MapMessage)
Unknown macro: \{ msg = (MapMessage) event.getMessage(); }
else
Unknown macro: \{ return; }{quote}
