Logging in Spring batch

I am new to spring batch. I want to know how we can put logging statement while implementing spring batch readers and writers. For example if I define readers and writers in spring context XML then later on I can't debug where my code failed. How can I achieve logging in Spring batch. Do I need to extend the available reader classes in java for example flatFileReader and put logging statement in java class.

Or can I achieve this while maintaining my code in context file?

And in case I want to throw my user defined exceptions then how can I do this.

There is an advanced listener architecture at Spring Batch API. You can use listener classes/interfaces to manage your logging such as ItemListenerSupport, ItemReadListener, ItemProcessListener or ItemWriteListener. Just implement/extend the class/interfaces that you need and customize the listener methods with overriding according to your needs.

For logging exceptions, please refer to this link.

Use Slf4j for logging, using sl4j you could log anything inside your batch job

 log.info("Converting (" + jobDetails + ") into (" + transformedJobDetails + ")");

Depending on what you want to debug, if you looking for debugging the out-of-the-box readers and writers, set up your log4j level to debug for the spring batch package.

###  debug your specific package or classes with the following example
#log4j.logger.org.springframework.jdbc=debug
#log4j.logger.org.springframework.batch=debug

Most of the out-of-box readers and writers should have sufficient debugging.
