public ExitStatus afterStep(StepExecution stepExecution)

    从接口复制的说明: StepExecutionListener
    Give a listener a chance to modify the exit status from a step. The value returned will be combined with the normal exit status using ExitStatus.and(ExitStatus). Called after execution of step's processing logic (both successful or failed). Throwing exception in this method has no effect, it will only be logged.
    指定者:
    afterStep 在接口中 StepExecutionListener
    参数:
    stepExecution - StepExecution instance.
    返回:
    an ExitStatus to combine with the normal value. Return null to leave the old value unchanged.
  - beforeStep
```
public void beforeStep(StepExecution stepExecution)
```
    从接口复制的说明: StepExecutionListener
    Initialize the state of the listener with the StepExecution from the current scope.
    指定者:
    beforeStep 在接口中 StepExecutionListener
    参数:
    stepExecution - instance of StepExecution.
