问题 I have following configuration: flow -> flow.handle(myHandler) .filter(p -> { log.warn("FILTER IS INVOKED"); return p != null; } In case if myHandler#handle returns null - filter is not invoked. How could I achieve passing null value to the filter ? 回答1: I came up with workaround: create wrapper over handler return type: class Wrapper { Foo foo; ... } At this case I can do following: flow -> flow.handle(myHandler) .filter(p -> { log.warn("FILTER IS INVOKED"); return p.getFoo() != null; } 来源：

问题 I'm new to Spring integration. Working with Spring 4, Only java anotations. The project where i'm working now we set up tcp connection in a property file. At the momet it is hardcoded to only 2 different connections and it must be changed to a more dynamic approach where we can set up a variable amount of them in the property file and be able to add new ones at runtime. I'm aware of the existence of dynamic tcp client example and tried to base my work on it. First we set up the following bean

问题 I am trying to check the status of my TCP Adapter whether it is connected or not. For this Spring provides a control bus command i.e @adapter_id.isConnected() for this purpose reference spring Documentation --> 32.6 TCP Adapters. The below code flow that provides the Id to the adapter: IntegrationFlow flow = IntegrationFlows.from(Tcp.inboundAdapter(Tcp.nioClient(hostConnection.getIpAddress(),Integer.parseInt(hostConnection.getPort())) .serializer(customSerializer) .deserializer

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 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 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 am trying to create a TCP server and client by reading the property files which contains the detail of the connections.
