How to log to different files using spring batch

[Kmisaal]

I am using log4j.properties files for logging.

log4j.appender.chainsaw=org.apache.log4j.RollingFileAppender
log4j.appender.chainsaw.File=import_log.xml
log4j.appender.chainsaw.Append=false
log4j.appender.chainsaw.Threshold=debug
log4j.appender.chainsaw.MaxFileSize=10MB
log4j.appender.chainsaw.MaxBackupIndex=2
log4j.appender.chainsaw.layout=org.apache.log4j.xml.XMLLayout 

log4j.rootCategory=info, format077Job
log4j.appender.format077Job.File=format077Job.xml
log4j.appender.format007Job=org.apache.log4j.RollingFileAppender
log4j.appender.format077Job.layout=org.apache.log4j.PatternLayout
log4j.appender.format077Job.layout.ConversionPattern=%d [%5p] %m%n


log4j.rootCategory=info, format529Job
log4j.appender.format529Job.File=format529Job.xml
log4j.appender.format529Job=org.apache.log4j.RollingFileAppender
log4j.appender.format529Job.layout=org.apache.log4j.PatternLayout
log4j.appender.format529Job.layout.ConversionPattern=%d [%5p] %m%n

However my both jobs format077job and format529job runs at the same time and log into same log file.

I want to have seperate log file for each job instance. So even if they run in parallel they will log to different log files. How I can achieve this please help.

Have you tried having a job listener (or step listener, depending upon how you are executing the job) and dynamically setting the log4j log file name in beforeJob (or beforeStep)?? Just a thought. let us know if that works.

Hi I tried some configuration in log4j.properties to log to different files.

I am using 2 different RollingFileAppender which are logging to different files.
And using them for different jobs.

log4j.appender.chainsaw=org.apache.log4j.RollingFileAppender
log4j.appender.chainsaw.File=/opt/oasis/bulk/log/import077.log
log4j.appender.chainsaw.Append=false
log4j.appender.chainsaw.Threshold=error
log4j.appender.chainsaw.MaxFileSize=10MB
log4j.appender.chainsaw.MaxBackupIndex=2
log4j.appender.chainsaw.layout=org.apache.log4j.xml.XMLLayout

log4j.appender.append529=org.apache.log4j.RollingFileAppender
log4j.appender.append529.File=/opt/oasis/bulk/log/import529.log
log4j.appender.append529.Append=false
log4j.appender.append529.Threshold=debug
log4j.appender.append529.MaxFileSize=10MB
log4j.appender.append529.MaxBackupIndex=2
log4j.appender.append529.layout=org.apache.log4j.xml.XMLLayout

log4j.rootCategory=error, format077Job
log4j.appender.format007Job=chainsaw
log4j.appender.format077Job.File=format077Job.xml
log4j.appender.format077Job.layout=org.apache.log4j.PatternLayout
log4j.appender.format077Job.layout.ConversionPattern=%d [%5p] %m%n


log4j.rootCategory=info, format529Job
log4j.appender.format529Job.File=format529Job.xml
log4j.appender.format529Job=append529
log4j.appender.format529Job.layout=org.apache.log4j.PatternLayout
log4j.appender.format529Job.layout.ConversionPattern=%d [%5p] %m%n

This way it is working however I don't know if this is the right way to do this.

In this case I have to configure different appender for all the jobs.

No of jobs = No of appender .....doesn't sound good ;-)
