MethodInvokingTaskletAdapter should store exception string in ExitStatus description [BATCH-1901]

Eric Quilantang opened BATCH-1901 and commented

I don't see exceptions details when the tasklet fails.
I extended MethodInvokingTaskletAdapter to make them show up in spring batch admin.

/**

• MyMethodInvokingTaskletAdapter
• on exception, this stores exception string in {@link ExitStatus}.
• {@link MethodInvokingTaskletAdapter} does not do this.
• @author eric.quilantang

*/
public class JqingMethodInvokingTaskletAdapter extends MethodInvokingTaskletAdapter {

@Override
public RepeatStatus execute(StepContribution contribution, ChunkContext chunkContext) throws Exception {
    try {
        return super.execute(contribution, chunkContext);
    } catch (Exception e) {
        ExitStatus status = new ExitStatus(ExitStatus.FAILED.getExitCode(), e.toString());
        contribution.setExitStatus(status);
    }
    return RepeatStatus.FINISHED;
}

}

Affects: 2.1.9

Start at MethodInvokingTaskletAdapter and inspect its execute path, especially how a tasklet failure sets ExitStatus. Confirm that the failure status exposes the exception string in its description, and verify the behavior with the relevant existing tests or a focused test if available.
