How to get job id using spring expression language?

Question

I want to get job id using spring expression language. I tried #{jobExecutionContext[jobId]} but it does not work.

Answer 1

Using SpEL alone, there is no way to access the job id. You could use a JobExecutionListener to add it to the executionContext and then it would be available via what you are trying.

Answer 2

A worked example would look like this. Your JobExecutionListener class has access to the JobExecution and it copies the jobId to the executionContext.

public class JobIdToContextExecutionListener implements JobExecutionListener {

    public void beforeJob(JobExecution jobExecution) {
        long jobId = jobExecution.getJobId();
        jobExecution.getExecutionContext().put("jobId",jobId);
    }

    ..
}

In your spring context, you can then reference the jobId via SpEL like

#{stepExecution.jobExecution.jobId}

or

#{jobExecutionContext.jobId}

See Luca's answer on referencing late-binding parameters here.

Answer 3

#{stepExecution.jobExecution.id} or #{stepExecution.jobExecutionId} should work though.

The StepContext does provide access to the StepExecution for late binding via SpEL expressions.

Answer 4

Use scope="step" and then an expression in your query (or its parameters): #{stepExecution.jobExecution.id} (the root of the expression is a StepContext).
