Class ExecutionContextPromotionListener

All Implemented Interfaces:
StepExecutionListener, StepListener, org.springframework.beans.factory.InitializingBean

public class ExecutionContextPromotionListener extends Object implements StepExecutionListener, org.springframework.beans.factory.InitializingBean
This class can be used to automatically promote items from the Step ExecutionContext to the Job ExecutionContext at the end of a step. A list of keys should be provided that correspond to the items in the Step ExecutionContext that should be promoted.

Additionally, an optional list of statuses can be set to indicate for which exit status codes the promotion should occur. These statuses will be checked using the PatternMatcher, so wildcards are allowed. By default, promotion will only occur for steps with an exit code of "COMPLETED".

      @Nullable public ExitStatus afterStep(StepExecution stepExecution)
      Description copied from interface: StepExecutionListener
      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.

      Specified by:
      afterStep in interface StepExecutionListener
      stepExecution - a StepExecution instance.
      an ExitStatus to combine with the normal value. Return null (the default) to leave the old value unchanged.

    • setKeys

      public void setKeys(String[] keys)
      keys - A list of keys corresponding to items in the Step ExecutionContext that must be promoted.
    • setStatuses

      public void setStatuses(String[] statuses)
      statuses - A list of statuses for which the promotion should occur. Statuses can may contain wildcards recognizable by a PatternMatcher.
    • setStrict

      public void setStrict(boolean strict)
      If set to TRUE, the listener will throw an exception if any 'key' is not found in the Step ExecutionContext. FALSE by default.
      strict - boolean the value of the flag.
