程序包 org.springframework.batch.integration.async

类 StepExecutionInterceptor

  • 所有已实现的接口:
    org.springframework.messaging.support.ChannelInterceptor
    public class StepExecutionInterceptor
extends org.springframework.messaging.support.ChannelInterceptorAdapter
    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.
