I am getting exception while consuming the messages from kafka. org.springframework.messaging.MessagingException: Consuming from Kafka failed; nested exception is java.util.concurrent.ExecutionException: java.lang.IllegalStateException: Iterator is in failed state I have one consumer in the application context with one outbound adapter.

I have a requirement to read and write compressed (GZIP) streams without intermediate storage. Currently, I'm using Spring RestTemplate to do the writing, and Apache HTTP client to do the reading (see my answer here for an explanation of why RestTemplate can't be used for reading large streams). The implementation is fairly straightforward, where I slap a GZIPInputStream on the response InputStream and move on. Now, I'd like to switch to using Spring 5 WebClient (just because I'm not a fan of status quo). However, WebClient is reactive in nature and deals with Flux<Stuff> ; I believe it's

I am experimenting with the Spring Reactor 3 components and Spring Integration to create a reactive stream (Flux) from a JMS queue. I am attempting to create a reactive stream (Spring Reactor 3 Flux) from a JMS queue (ActiveMQ using Spring Integration) for clients to get the JMS messages asynchronously. I believe that I have everything hooked up correctly but the client does not receive any of the JMS messages until the server is stopped. Then all of the messages get "pushed" to the client a once. Any help would be appreciated. Here is the configuration file that I am using to configure the

How can I move file from local system to remote FTP using SFTP adapter. I am going through the examples and all are mentioning to copy files from remote FTP to local machine. I need to move files from local machine to remote system folder. <?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:int="http://www.springframework.org/schema/integration" xmlns:int-sftp="http://www.springframework.org/schema/integration/sftp" xmlns:file="http://www.springframework.org/schema/integration/file" xsi

Is it possible to programmatically create / teardown Spring Integration channels, as opposed to declaring them statically in Spring config? My situation is this: I have a webapp that requires push notifications, so I'm using long polling. Those long polling calls need to block on the server until they get an event. What I'm envisioning (open to alternatives, of course), is a Spring Integration queue channel for each session , each listening to a single pubsub channel. So, when a server event happens it will be published to the pubsub, which will then pipe down to the individual session queues

I'm trying to move files on remote SFTP once the batch has successfully processed the files using Spring integration and Java DSL. What would be the best way to achieve that? Adding a step in batch to move remote files ? Or using FTP Outbound Gateway and provide the MV command ? I tend to prefer the second solution and let the batch focus on the logic only, but I've hard times trying to implement it with java dsl. I've read http://docs.spring.io/spring-integration/reference/html/ftp.html#ftp-outbound-gateway and tried to implement like that : @Bean public MessageHandler ftpOutboundGateway() {

Just a simple question: Is there any way to configure Spring Integration Control Bus via annotations (without any xml) <control-bus input-channel="operationChannel"/> ? @Bean @ServiceActivator(inputChannel = "controlBusChannel") public ExpressionControlBusFactoryBean controlBus() throws Exception { ExpressionControlBusFactoryBean controlBus = new ExpressionControlBusFactoryBean(); return controlBus; } Note that any outputChannel on the annotation will be ignored; it is defined on the bus itself. Typically the output channel of a control bus is omitted with the result of normal request/reply
