I want to configure InboundChannelAdapter so that it should pop message from a redis queue and pass it to a ServiceActivator in Java based annotations(only, prefer to avoid XML). I found the code from Spring documentation: @Bean("someAdapter.source") @EndpointId("someAdapter") @InboundChannelAdapter(channel = "channel3", poller = @Poller(fixedDelay = "5000")) public MessageSource<?> source() { return () -> { ... }; } But what I do not understand here is, how can I return MessageSource by poping the data from redis queue using redisConnectionFactory? In other words, how can I do this in java

I have the following http outbound gateway. How can I do this configuration with Java Config or Spring DSL? <int-http:outbound-gateway id="test" url="http://localhost:8080/" http-method="POST" charset="UTF-8" header-mapper="soapHeaderMapper" request-factory="requestFactory" request-channel="inputChannel"/> @Bean public IntegrationFlow httpOut() { return IntegrationFlows.from("inputChannel") .handle(Http.outboundGateway("http://localhost:8080/") .charset("UTF-8") .httpMethod(HttpMethod.POST) .headerMapper(soapHeaderMapper()) .requestFactory(requestFactory()), e -> e.id("test")) .get(); } Or

I have configured CachingConnectionFactory that wraps a MQTopicConnectionFactory and MQQueueConnectionFactory with cache size set to 10 each. These are than used in several jms:outbound-channel-adapter or jms:message-driven-channel-adapter as part of various spring integration workflows that I have in my application. It is noticed that once in a while the connection count on MQ channel reaches maximum allowed (about 1000) when the process stops functioning. This is a serious problem for a production application. Bringing the application down does not reduce the connection count so looks like

We are quite happy with spring-integration except when things do not work as expected. Then it is really difficult to find out what is going on (we are using xml configuration). Can someone point me to the java components behind the spring integration components in order to debug them. For instance: If I have a headerValueRouter, where can I set a breakpoint to find out what is the actual value of the header inside the message, just before the component is doing the routing. Maybe there is even a list int:component->java class? True. The list exists, but it isn't so direct, as you may expect.

According to the documentation provided here , I am trying on a POC to get messages into a listener as mentioned in the the same documentation , Below is how I have written the configuration. @Configuration public class KafkaConsumerConfig { public static final String TEST_TOPIC_ID = "record-stream"; @Value("${kafka.topic:" + TEST_TOPIC_ID + "}") private String topic; @Value("${kafka.address:localhost:9092}") private String brokerAddress; /* @Bean public KafkaMessageDrivenChannelAdapter<String, String> adapter( KafkaMessageListenerContainer<String, String> container) {

I have a self-executable jar program that relies heavily on Spring Integration. The problem I am having is that the program is terminating before the other Spring beans have completely finished . Below is a cut-down version of the code I'm using, I can supply more code/configuration if needed. The entry point is a main() method, which bootstraps Spring and starts the import process: public static void main(String[] args) { ctx = new ClassPathXmlApplicationContext("flow.xml"); DataImporter importer = (DataImporter)ctx.getBean("MyImporterBean"); try { importer.startImport(); } catch (Exception e

I am trying to build a module to be deployed on multiple nodes using Spring boot. Due to time constraints of the specific application, I have to use UDP and cannot rely on the easier-to-use REST facilities that Spring provides. I have to be able to send datagrams to a set of nodes that may vary in time (i.e. the set may grow or shrink, or some nodes may move to new ip/port "coordinates"). Communication must be unicast . I have been reading the official documentation about TCP and UDP support TCP and UDP support , but it is rather... compact, and opaque. The javadocs on the org.springframework
