Regarding the answer posted for How can @MessagingGateway be configured with Spring Cloud Stream MessageChannels? , what is the correct way to handle errors at the @MessagingGateway that can be returned from Spring Cloud Stream services? To recap, I have a @MessagingGateway that provides synchronous access to asynchronous services built using Spring Cloud Stream. When an error occurs within my Spring Cloud Stream service layer, I create an error response and send it through a SubscribableChannel to other @StreamListener services that process the errors. For example, when an account is created,

I'm using Spring Integration for TCP server which keeps connections to a few thousand clients. I need the server to throttle clients in case of excessive load and not to lose messages. My server configuration: <task:executor id="myTaskExecutor" pool-size="4-8" queue-capacity="0" rejection-policy="CALLER_RUNS" /> <int-ip:tcp-connection-factory id="serverTcpConFact" type="server" port="60000" using-nio="true" single-use="false" so-timeout="300000" task-executor="myTaskExecutor" /> <int-ip:tcp-inbound-channel-adapter id="tcpInboundAdapter" channel="tcpInbound" connection-factory="serverTcpConFact

How to move a file after processing in spring integration after processing file ..? I have followed http://xpadro.blogspot.com/2016/07/spring-integration-polling-file.html to implement the file polling , but I need to add onSuccess and OnError transnational events (with out XML configurations) I am not sure what you mean by "transaction", file systems are generally not transactional, but you can add an advice to the final consumer in the flow... @SpringBootApplication public class So40625031Application { public static void main(String[] args) { SpringApplication.run(So40625031Application.class

Let's consider the following context: 2 spring integration channels, they are each in separate database transactions. At the end of the first transaction, a message is put into the second channel. In the first channel, elements are created in the database that is later consumed by the corresponding message that has been sent from the first channel to the second channel. To make sure that the transaction from channel 1 is fully committed before the second channel is triggered our subclass of the JpaTransactionManager is registering a TransactionSynchronization in the prepareForCommit method it

I want to implement the HTTP endpoint using Spring Integration, which listen to the http requests, sends the request data as messages to the channel and another endpoint should listen messages on this channel and process them. Sounds simple. But what I want to achieve is: Messages should be processed in order. Messages should be processed asap (without delay after http request, if the queue is already empty). The http request should be responded as soon as message is received, not after it is processed, so the sender will know only that message is received for processing. I don't want to use
