Spring Integration - programmatically create / teardown channels

阅读更多关于 Spring Integration - programmatically create / teardown channels

问题 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

Spring Integration - Inbound vs Outbound Channel Adapters

阅读更多关于 Spring Integration - Inbound vs Outbound Channel Adapters

What is the fundamental difference between inbound and outbound channel adapters? Any examples would be very helpful. I have reviewed the Spring docs and this "directional" distinction is not clear to me. I support an application that has an outbound-channel-adapter configured, but I find the behavior counter intuitive with the outbound label. This adapter gets an external file, then brings it in to the application where we parse the file and persist the data. This is similar to this question, but I wanted to focus more generally on channel adapters, and hopefully get more feedback! Thanks!

How to control the number of parallel Spring Batch jobs

阅读更多关于 How to control the number of parallel Spring Batch jobs

I have a report generating application. As preparation of such reports is heavyweight, they are prepared asynchronously with Spring Batch. Requests for such reports are created via REST interface using HTTP. The goal is that the REST resource simply queues report execution and completes ( as described in documentation ). Thus a TaskExecutor has been provided for the JobLauncher: <bean id="jobLauncher" class="org.springframework.batch.core.launch.support.SimpleJobLauncher"> <property name="jobRepository" ref="jobRepository" /> <property name="taskExecutor"> <bean class="org.springframework.core

Move file after successful ftp transfer using Java DSL

阅读更多关于 Move file after successful ftp transfer using Java DSL

问题 I've defined a flow using spring-integration java dsl to ftp transfer a file, handle it, then transfer it back in an "archive" dir, and at last move it in a local archive dir. Which is something "quite easy" as: @Bean public IntegrationFlow ftpInboundFlow() { if (ftpProperties.getEnabled() == false) { return null; } logger.trace("Starting ftp flow"); return IntegrationFlows .from(source -> source.ftp(ftpSessionFactory()).deleteRemoteFiles(true).preserveTimestamp(true) .filter

问题 I have a gradle project in my Eclipse with a number of spring-integration context XMLs. These context XML files used to validate okay against the spring-integration schemas but now, for some reason, they are showing 'cvc-complex-type' errors. e.g. I have an element with an error-channel attribute. But on validation, it has started saying: "cvc-complex-type.3.2.2: Attribute 'error-channel' is not allowed to appear in element 'int:gateway'." Now, looking in my Eclipse preferences' General ->

阅读更多关于 how to plug a TCP-IP client server in a spring MVC application

问题 I wonder if it is possible to plug a bidirectional connection between a spring mvc application and a legacy system working with TCP-IP connections. as mentionned the legacy system works with TCP/ip and not http , so no need to talk about how HTTP is better , thanks ! 回答1: See Spring Integration. You can simply wire an SI flow into your MVC controller using a messaging gateway Controller->gateway->{optional filtering/transforming}->tcp outbound gateway The gateway is injected into the

阅读更多关于 Spring Integration Control Bus configuration via annotations

问题 Just a simple question: Is there any way to configure Spring Integration Control Bus via annotations (without any xml) <control-bus input-channel="operationChannel"/> ? 回答1: @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
