The best choice to solve your problem is to use a JobExecutionDecider where you perform filename validation and stop job or move to next step

Hansjoerg's answer is a valid point. Still as for how to achieve what you're trying to do, here's an example :

@Override
public ExitStatus afterStep(StepExecution stepExecution) {
    return ExitStatus.FAILED;
}

This will return an ExitStatus FAILED that you can use on your <next on="" /> tag to prevent from going into the reader.

The listener is the wrong place to do data validation. use a processor and throw an appropriate exception if you have to validate single data items.

Use a tasklet step prior to a processing step if you want to validate more "general" aspects like the filename or the presence of a file or any other condition that is not part of single item.
