Package org.springframework.batch.integration.async

Class StepExecutionInterceptor

java.lang.Object
org.springframework.batch.integration.async.StepExecutionInterceptor
All Implemented Interfaces:
org.springframework.messaging.support.ChannelInterceptor
public class StepExecutionInterceptor extends Object implements org.springframework.messaging.support.ChannelInterceptor
A ChannelInterceptor that adds the current StepExecution (if there is one) as a header to the message. Downstream asynchronous handlers can then take advantage of the step context without needing to be step scoped, which is a problem for handlers executing in another thread because the scope context is not available.
