Method Details

beforeStep

default void beforeStep(StepExecution stepExecution)

Initialize the state of the listener with the StepExecution from the current scope.

Parameters:

stepExecution - instance of StepExecution.

afterStep

@Nullable
default ExitStatus afterStep(StepExecution stepExecution)

Give a listener a chance to modify the exit status from a step. The value returned is combined with the normal exit status by using ExitStatus.and(ExitStatus).

Called after execution of the step's processing logic (whether successful or failed). Throwing an exception in this method has no effect, as it is only logged.

Parameters:

stepExecution - a StepExecution instance.

Returns:

an ExitStatus to combine with the normal value. Return null (the default) to leave the old value unchanged.
