MDC to log entire dynamic message, irrespective of no of entries in MDC

问题

I want to use MDC for logging for that I'm doing

 MDC.put("ReportName", "IOR_Report");
 MDC.put("ReportJNDI", JNDI_NAME.getValue());
 log.info("Report logger working");

And added below entry in log4j.properties and it's printing correct ReportName="My ReportName" JNDI=MYJNDI

log4j.appender.REPORTSLOG = org.apache.log4j.RollingFileAppender
log4j.appender.REPORTSLOG.layout = org.apache.log4j.PatternLayout
log4j.appender.REPORTSLOG.File = ../logs/ReportLog.log
log4j.appender.REPORTSLOG.Threshold=INFO
log4j.appender.REPORTSLOG.layout.ConversionPattern=%m - ReportName=%X{ReportName} JNDI=%X{ReportJNDI}%n

But I want to add these parameters to MDC dynamically,and so don't want to hardcode like below

ReportName=%X{ReportName} JNDI=%X{ReportJNDI}%n

It should show all MDC parameters which are added in MDC, something like below I'm expecting but it's not working, what m I missing here?

 log4j.appender.REPORTSLOG.layout.ConversionPattern=%m - %X - %n
