Package org.springframework.batch.core.listener

Class ExecutionContextPromotionListener

java.lang.Object
org.springframework.batch.core.listener.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".

      Parameters:
      stepExecution - StepExecution instance.
