spring-integration

问题 This looks like a beginner question to me. For the sake of easy reproduction, I have stripped out virtually all of my logic from this flow. The reason it looks like it does nothing is because it, quite literally, fetches data from a JDBC endpoint and does exactly nothing. setupAdapter = new JdbcPollingChannelAdapter(dbprx.getDatasource(), sql.getSql()); setupAdapter.setRowMapper(rowMapper); StandardIntegrationFlow flow = IntegrationFlows .from(setupAdapter, c -> c.poller(Pollers.fixedRate

问题 I have a scenario to split a large files to small chunks using File Inbound, Splitter, Transformer and File Outbound adapter. I would like to know how long it took to process the file starting from read to split to write back. How do I achieve this functionality? Any help is appreciated. <file:inbound-channel-adapter directory="/Documents" filename-pattern="test.txt" channel="inputFiles"> <int:poller fixed-delay="0"/> </file:inbound-channel-adapter> <int:channel id="inputFiles"> <int

问题 I've a TCP client which was built using spring integration TCP and the server supports a keep alive message (ping/pong style). The connections were configured using a CachingClientConnectionFactory and I'd like to take advantage on this server feature.

问题 Sometimes, when we are stopping the application abruptly exception occurs that unlocking has been failed. Then the same group will never gets the messages. Other groups are getting messages.

问题 On my gateway, I have a method @Gateway String commsTest(); The idea is that I can call commsTest from the bean and use spring integration to wire it up to the service activator that will check comms. When I do that I get a receive is not supported, because no pollable reply channel has been configured error. I realise that this is because a method with no params means "I am trying to poll a message from the channel" This is a two part question. What does it mean to poll a message from the

问题 I am using Spring Batch Integration as I have to perform certain works before invoking the batch. I have done the work using Spring Integration and invoke the batch using job-launching-gateway and it works like a charm. Now the question is how to pass the data from Spring Integration to Batch? Suggestions please. 回答1: The message sent to the JobLaunchingGateway has a JobLaunchRequest payload. When you build the request in your Spring Integration flow, you can add JobParameters which are then
