Our application uses a Spring Integration file:inbound-channel-adapter to poll a directory to listen to when a file is dropped there. Spring Integration then starts a Spring Batch job, handing over to the job the path and name of the file to process. Obviously, the file poller continues to run even after a file has been processed by the Spring Batch job. So, the Spring context remains open and the application does not terminate. Is there a way, programatically or through configuration (preferable), to stop the poller after one file has been read? Thanks Gary Russell You can use a

I use Spring Integration tcp-outbound-adapter and tcp-inbound-adapter in order to communicate with a third party external system through TCP. The connection factory I use is of type "client" and has single-use="false", because the nature of communication with the external system is a session of several dozens requests and replies. The external system expects I will open a new TCP connection for each session. Is there any way to do that with Spring Integration? My code uses SI successfully for one such session. But I want my system to open several such connections so I can handle several

I have developed asynchronous Spring Cloud Stream services, and I am trying to develop an edge service that uses @MessagingGateway to provide synchronous access to services that are async by nature. I am currently getting the following stack trace: Caused by: org.springframework.messaging.core.DestinationResolutionException: no output-channel or replyChannel header available at org.springframework.integration.handler.AbstractMessageProducingHandler.sendOutput(AbstractMessageProducingHandler.java:355) at org.springframework.integration.handler.AbstractMessageProducingHandler.produceOutput

I have a web application that has a Spring Integration logic running with it in a separated thread. The problem is that at some point my Spring Integration logic tries to use a request scoped bean and then i get the following errors: Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'scopedTarget.tenantContext': Scope 'request' is not active for the current thread; consider defining a scoped proxy for this bean if you intend to refer to it from a singleton; nested exception is java.lang.IllegalStateException: No thread-bound request found: Are

Is it possible in Spring integration to keep the channels synchronous (get acknowledgement after sending the message) but process more messages at the same time (process in parallel) without creating own code with threads (i.e. ExecutorService execute and submit worker) and awaiting on them? I would like to upload files through FTP using but uploading more at the same time without creating own threads in the code. I need to know when all files are uploaded (that is why I want it to be synchronous). Is it possible via Spring integration configuration and, if so, how? Well, looks like you need

I am new to Spring batch and couldn't figure out how to do this.. Basically I have a spring file poller which runs every N mins to look for files with some name (ex: A.txt & B.txt) in certain directory. At any moment in time, there could be max 2 files in this directory (A and B). Through Spring Batch Job, these two files will be processed and persisted to 2 different DB tables. These files are somewhat similar, so the same processor/writer is used. Right now the way I set up, every polling cycle 1 file is picked up and job is ran. Let's say there are 2 files in the directory (A.txt and B.txt)
