How to get access to job parameters from ItemReader, in Spring Batch?

Question

This is part of my job.xml:

Answer 1

While executing the job we need to pass Job parameters as follows:

JobParameters jobParameters= new JobParametersBuilder().addString("file.name", "filename.txt").toJobParameters();   
JobExecution execution = jobLauncher.run(job, jobParameters);  

by using the expression language we can import the value as follows:

 #{jobParameters['file.name']}
