如果Spring批处理作业在后台运行，将更新SQL结果状态，那么如何更新JSP状态（从提交到处理然后成功）

Question

I have a jsp that initiates a long running background process. It will update status first submitted when it call the job in between it will update processing and at last it updates as success

I need to send the user some feedback during the processing time and at the same time prevent the session from timing out.

Does anyone have some details (sample code) on how this can be done? currently the user just sits and waits with no status on the screen...which is bad. At the end of processing there is an sql result that needs to be displayed on the screen.

Answer 1

Try doing that using the job's status from the SB tables. I think it is in the BATCH_JOB_EXECUTION table.
