Example 1 with ErrorMessageStrategy

use of org.springframework.integration.support.ErrorMessageStrategy in project spring-cloud-stream by spring-cloud.

the class AbstractMessageChannelBinder method registerErrorInfrastructure.

 * when an exception is thrown to a consumer.
 * @param destination the destination.
 * @param group the group.
 * @param consumerProperties the properties.
 * @param polled true if this is for a polled consumer.
 * @return the ErrorInfrastructure which is a holder for the error channel, the recoverer and the
 * message handler that is subscribed to the channel.
