Parse in job parameters from the command line and then create and populate JobParameters.
public JobParameters getJobParameters() {
JobParametersBuilder jobParametersBuilder = new JobParametersBuilder();
jobParametersBuilder.addString("dest", <dest_from_cmd_line);
jobParametersBuilder.addDate("date", <date_from_cmd_line>);
return jobParametersBuilder.toJobParameters();
}
Pass them to your job via JobLauncher -
JobLauncher jobLauncher = context.getBean(JobLauncher.class);
JobExecution jobExecution = jobLauncher.run(job, jobParameters);
Now you can access them using code like -
@Bean
@StepScope
public Resource destFile(@Value("#{jobParameters[dest]}") String dest) {
return new FileSystemResource(dest);
}
Or in a @Configuration class that is configuring Spring Batch Job artifacts like - ItemReader, ItemWriter, etc...
@Bean
@StepScope
public JdbcCursorItemReader<MyPojo> reader(@Value("#{jobParameters}") Map jobParameters) {
return new MyReaderHelper.getReader(jobParameters);
}

Access Job Parameters From ItemReader in Spring Batch | Baeldung
July 6, 2024 - As we’ll configure only one job, spring.batch.job.enabled should be set to false to disable the initial job execution. By default, Spring runs the job after the context startup with empty parameters:

I managed to get this working by simply annotating my bean as follows :
@Bean
@StepScope
public Resource destFile(@Value("#{jobParameters[dest]}") String dest) {
return new FileSystemResource(dest);
}

November 23, 2022 - This is useful when, for instance, ... that a job is started with all its mandatory parameters. There is a DefaultJobParametersValidator that you can use to constrain combinations of simple mandatory and optional parameters. For more complex constraints, you can implement the interface yourself. Spring 3 brought the ability to configure applications with Java instead of XML. As of Spring Batch 2.2.0, you ...

JobParameters can be used for identification during the job run. They have reserved names, so to access them we can use Spring Expression Language For example we can provide the following as job parameters- File path of the source location containing the files to be processed by String Batch

Job parameters
It assigns ID (RUN_ID) that identifies job execution to parameter with the name jsr_batch_run_id automatically. It increments the RUN_ID each time the job is executed. Since it uses SEQUENCE (name is JOB_SEQ) of the database for incrementing, the name does not overlap. In Spring Batch, runnaing the job by the same parameters is identified as the same job and the same job can be executed only once.

JobParameters (Spring Batch 5.2.5 API)
Value object representing runtime parameters to a batch job. Because the parameters have no individual meaning outside of the JobParameters object they are contained within, it is a value object rather than an entity. It is also extremely important that a parameters object can be reliably compared to another for equality, in order to determine if one JobParameters object equals another.
