Ralph Goers commented on LOG4J2-2341:
-------------------------------------
OK. Based on that I have modified my fix in LOG4J2-913 to wrap the LogEvent in
another LogEvent that only implements the LogEvent interface by calling the
methods on the wrapped event which is the same as what you did. However, I
merged the logic to do that into wrapLogEvent as I don't see the point of
possible having a wrapper around a wrapper.
> JsonLayout not working with AsyncLoggerContextSelector in 2.11.0
> ----------------------------------------------------------------
>
> Key: LOG4J2-2341
> URL: https://issues.apache.org/jira/browse/LOG4J2-2341
> Project: Log4j 2
> Issue Type: Bug
> Affects Versions: 2.11.0
> Reporter: Fedor Morozov
> Assignee: Carter Kozak
> Priority: Major
> Fix For: 3.0.0, 2.11.1
>
>
> In version 2.11.0 appenders with JsonLayout don't output json when
> Log4jContextSelector is set to
> org.apache.logging.log4j.core.async.AsyncLoggerContextSelector.
> Here is a sample:
> {code:java}
> package ru.yandex.zen;
> import org.apache.log4j.Logger;
> public class LoggerSample {
> public static void main(String[] args) {
> Logger logger = Logger.getLogger("LoggerSample");
> logger.info("Message 1");
> logger.info("Message 2");
> }
> }
> {code}
> {code:java}
> <?xml version="1.0" encoding="UTF-8"?>
> <Configuration status="WARN">
> <Appenders>
> <RandomAccessFile name="RandomAccessFile" fileName="async.log"
> immediateFlush="false" append="false">
> <JsonLayout/>
> </RandomAccessFile>
> </Appenders>
> <Loggers>
> <Root level="info">
> <AppenderRef ref="RandomAccessFile"/>
> </Root>
> </Loggers>
> </Configuration>
> {code}
> Without AsyncLoggerContextSelector the log looks like this:
> {code:java}
> ""
> ""
> {code}
> Without AsyncLoggerContextSelector:
> {code:java}
> {
> "thread" : "main",
> "level" : "INFO",
> "loggerName" : "LoggerSample",
> "message" : "Message 1",
> "endOfBatch" : false,
> "loggerFqcn" : "org.apache.log4j.Category",
> "instant" : {
> "epochSecond" : 1527061940,
> "nanoOfSecond" : 637000000
> },
> "threadId" : 1,
> "threadPriority" : 5
> }
> {
> "thread" : "main",
> "level" : "INFO",
> "loggerName" : "LoggerSample",
> "message" : "Message 2",
> "endOfBatch" : false,
> "loggerFqcn" : "org.apache.log4j.Category",
> "instant" : {
> "epochSecond" : 1527061940,
> "nanoOfSecond" : 717000000
> },
> "threadId" : 1,
> "threadPriority" : 5
> }
> {code}
> In our main application Json logger outputs the provided message in quotes,
> not just an empty string. The problem doesn't appear when using asyncRoot or
> asyncLogger.
> My dependencies:
> {code:java}
> compile 'org.apache.logging.log4j:log4j-api:2.11.0'
> compile 'org.apache.logging.log4j:log4j-core:2.11.0'
> compile "org.apache.logging.log4j:log4j-1.2-api:2.11.0"
