This is the output of TcpSocketServer :

> Key: LOG4J2-1969
> URL: https://issues.apache.org/jira/browse/LOG4J2-1969
> Project: Log4j 2
> Issue Type: Bug
> Components: Appenders
> Affects Versions: 2.6.2, 2.7
> Environment: Spring boot 1.5.4
> java 8
> Reporter: YU Chang
>
> I have a spring boot(v1.5.4) web application which use log4j-2.7 for logging.
> It works well when write log message to file or console, but when send
> message to `TcpSocketServer`, the log server just output the message without
> the "{}" formatting. for example, for this code:
> {code:java}
> logger.info("Request from [{}] to [{}]", ipInfo, reqPath);
> {code}
> The `RollingfileAppender` and `ConsoleAppender` will output:
> {code:none}
> INFO 2017-07-06 16:46:07,929 [127.0.0.1][/senten/align] AuthFilter
> (http-nio-8180-exec-2) Request from [127.0.0.1] to [/senten/align]
> {code}
> But the `SocketAppender` just ouput:
> {code:none}
> INFO 2017-07-06 16:46:07,929 [127.0.0.1][/senten/align] AuthFilter
> (http-nio-8180-exec-2) Request from [{}] to [{}]
> {code}
> This is my config with `SocketAppenders` in log4j.xml
> {code:xml}
> <Appenders>
> <Socket name="socket" host="127.0.0.1" port="9898">
> <SerializedLayout />
> </Socket>
> ........
> </Appenders>
> {code}
> This is my config file `log4j2-socket.xml` for `TcpSocketServer`:
> {code:xml}
> <Configuration status="WARN">
> <Appenders>
> <RollingFile name="default" fileName="Logs/app.log"
>
> filePattern="Logs/${date:yyyy-MM}/app-%d{yyyy-MM-dd}-%i.log.gz">
> <PatternLayout>
> <Pattern>%-5p %d [%X{ip}][%X{reqPath}] %c{1}
> (%t) %m %ex%n</Pattern>
> </PatternLayout>
> <Policies>
> <TimeBasedTriggeringPolicy interval = "30"
> modulate="true"/>
> <SizeBasedTriggeringPolicy size="200 MB" />
> </Policies>
> </RollingFile>
> </Appenders>
> <Loggers>
> <Root level="DEBUG">
> <AppenderRef ref="default" level="DEBUG" />
> </Root>
> </Loggers>
> </Configuration>
> {code}
> And, I use this command for start `TcpSocketServer`:
> {code:none}
> java -classpath log4j-core-2.7.jar:log4j-api-2.7.jar:jcommander-1.48.jar
> org.apache.logging.log4j.core.net.server.TcpSocketServer -p 9898 -c
> log4j2-socket.xml
> {code}
> What am I doing wrong? How to fix it? Thanks!
