春季批处理中有最后一个tasklet吗？

Question

Is there a finally tasklet in spring batch? This task always gets executed regardless of if execution was cancelled, or if a task exceptions out. This is used to do any sort of cleanup.

I am not finding any useful listeners in documentation. Any help will be appreciated.

JobExecutionListener#afterJob is what you are looking for. It is always called, regardless of the job exit status. It is the right place to implement any clean-up code.

Hope this helps.
