spring-integration

问题 NOTE WELL: I am NOT running eclipse. I am running a standalone Spring application from the command line with maven. When I attempt to send a message to an outbound channel adapter created with IoC using spring-integration-mqtt 4.3.8, I get java.lang.ExceptionInInitializerError at org.springframework.integration.mqtt.core.DefaultMqttPahoClientFactory.getAsyncClientInstance(DefaultMqttPahoClientFactory.java:147) at org.springframework.integration.mqtt.outbound.MqttPahoMessageHandler

问题 I am using Spring Integration DSL configs. Is it possible to add a method reference handler such that the handler is invoked only when the message payload matches the handler argument type? For example: in the following code, if the payload is MyObject2 , Spring will throw ClassCastException at handleMessage . Instead, what I want to do is to bypass handleMessage and get picked up by handleMessage2 . @Bean public IntegrationFlow myFlow() { return IntegrationFlows .from("myChannel") .handle

问题 I am getting InstanceAlreadyExistsException while trying to deploy in tomcat 8 in linux server the code with Spring Integration having 2 separate flows.

问题 I am new to Spring Boot but have been requested by my job to implement a small web service using spring boot. The web service needs to accept SSL TCP connections (an external system will connect to my web service using a custom protocol - NOT HTTP). Also, I would like to handle these connections in a background task (or multiple background tasks). After looking at the official documentation (http://docs.spring.io/spring-integration/reference/html/ip.html), I still don't understand (where do I

问题 I'me using Spring Integration and java dsl specifications to implement my IntegrationFlow. I want to use an custom header enricher to add some file names to the header, it will be something like : public class FileHeaderNamingEnricher { public Message<File> enrichHeader(Message<File> fileMessage) { // getting some details fom the database ... return messageBuilder .setHeader("filename", "somestuff") .build(); } } And my Integration flow will look like : public IntegrationFlow myflow() {

问题 I want to be able to process more than 10 SQS messages at a time using a Spring Integration Workflow. From this question, the recommendation was to use an ExecutorChannel . I updated my code but still have the same symptoms. How execute Spring integration flow in multiple threads to consume more Amazon SQS queue messages in parallel? After making this update, my application requests 10 messages, processes those, and only after I make the call to amazonSQSClient.deleteMessage near the end of

问题 i am using spring-integration to develop a customized two-way tcp socket server. the server will process request / response tasks but i am not able to send an arbitrary message to specific connection-Id also i know maybe using TcpSendingMessageHandler and TcpReceivingChannelAdapter is the solution , but i was not able to find any sample code about how to use that. here is my code : public class SocketServer { private Logger logger = LoggerFactory.getLogger(SocketServer.class); @Bean public

问题 Followup question for https://stackoverflow.com/a/47136941/1776585 I can't make my integration handler to run in parallel threads while using Flux + split() + FluxMessageChannel . Consider the following snippet: // ... .handle(message -> Flux.range(0, 10) .doOnNext(i -> LOG.info("> " + i)) .subscribeOn(Schedulers.parallel())) .split() .channel(new FluxMessageChannel()) .handle(message -> LOG.info(" -> " + message.getPayload()))) // ... All logs are output in one thread: [ parallel-1] d.a

问题 I have setup File poller with task executor ExecutorService executorService = Executors.newFixedThreadPool(10); LOG.info("Setting up the poller for directory {} ", finalDirectory); StandardIntegrationFlow standardIntegrationFlow = IntegrationFlows.from(new CustomFileReadingSource(finalDirectory), c -> c.poller(Pollers.fixedDelay(5, TimeUnit.SECONDS, 5) .taskExecutor(executorService) .maxMessagesPerPoll(10) .advice(new LoggerSourceAdvisor(finalDirectory)) )) //move file to processing first

问题 I've got an integration flow that looks like the following: @Bean public IntegrationFlow auditFlow(@Qualifier("eventLoggingConnectionFactory") ConnectionFactory connectionFactory, @Qualifier("writeChannel") MessageChannel messageChannel, @Qualifier("parseErrorChannel") MessageChannel errorChannel) { return IntegrationFlows .from(Amqp.inboundAdapter(connectionFactory, auditQueue) .errorChannel(errorChannel) .concurrentConsumers(numConsumers) .messageConverter(new MongoMessageConverter())) //
