--------------------------------

             Summary: TcpSocketServer does not replace any “{}” in message
                 Key: LOG4J2-1969
                 URL: https://issues.apache.org/jira/browse/LOG4J2-1969
             Project: Log4j 2
          Issue Type: Bug
          Components: Appenders
    Affects Versions: 2.7, 2.6.2
         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:

    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] 

But the `SocketAppender` just ouput:

    INFO  2017-07-06 16:46:07,929 [127.0.0.1][/senten/align] AuthFilter 
(http-nio-8180-exec-2) Request from [{}] to [{}] 

This is my config with `SocketAppenders` in log4j.xml


    <Appenders>
                <Socket name="socket" host="127.0.0.1" port="9898">
                        <SerializedLayout />
                </Socket>
        ........
        </Appenders>


This is my config file `log4j2-socket.xml` for `TcpSocketServer`:

    <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>

And, I use this command for start `TcpSocketServer`:

    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

Does anybody know what's going wrong here, and how to fix it? Thanks!
