Spring Batch + Spring API REST

I have set up a java batch project with spring batch that allows to persist the rows of a CSV in a table of a database. I would have liked to know if it was possible with Spring API REST to trigger the Batch with a POST method that would join the necessary CSV.

thank you in advance

You can do that using a Controller with a JobLauncher and Job. The barebones of the controller would be like this

@RestController
public class MyController{
    // Usually given by Spring Batch
    private JobLauncher jobLauncher;
    // Your Job
    private Job job;
    // Ctor
    public MyController(JobLauncher jobLauncher, Job job, ...){}

    @PostMapping("/")
    public String launchJob(...){
        ...
        // Create JobParameters and launch
        JobParameters jobparameters = new Job Parameters();
        jobLauncher.run(job, jobParameters);
        ...
    }
}

SimpleJobLauncher, the implementation of JobLauncher, uses a synchronous executor by default, you'll probably want to change it to an Async one depending of your requirements
