Why does Spring Integration have several XML schemas, and which one should I use?

阅读更多关于 Why does Spring Integration have several XML schemas, and which one should I use?

问题 To use Spring Integration in a Spring XML configuration file, I need to declare the si namespace, and provide the schema location of the XML Schema: <?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:int="http://www.springframework.org/schema/integration" xsi:schemaLocation="http://www.springframework.org/schema/integration http://www.springframework.org/schema/integration/spring

Stopping a file inbound channel adapter after one one file is read

阅读更多关于 Stopping a file inbound channel adapter after one one file is read

问题 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

Spring Integration tcp client multiple connections

阅读更多关于 Spring Integration tcp client multiple connections

问题 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

When to use Spring Integration vs. Camel?

阅读更多关于 When to use Spring Integration vs. Camel?

As a seasoned Spring user I was assuming that Spring Integration would make the most sense in a recent project requiring some (JMS) messaging capabilities ( more details ). After some days working with Spring Integration it still feels like a lot of configuration overhead given the amount of channels you have to configure to bring some request-response (listening on different JMS queues) communications in place. Therefore I was looking for some background information how Camel is different from Spring Integration, but it seems like information out there are pretty spare, I found: http://java

问题 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

spring integration + cron + quartz in cluster?

阅读更多关于 spring integration + cron + quartz in cluster?

I have a spring integration flow triggered by the cron expression like follows: <int-ftp:inbound-channel-adapter id="my-input-endpoint" ...> <int:poller trigger="my-trigger"/> </int-ftp:inbound-channel-adapter> <bean id="my-trigger" class="org.springframework.scheduling.support.CronTrigger"> <constructor-arg value="0 * * * * *" /> </bean> It works fine. But now I have to extend the implementation to make it cluster ready (job execution on only one cluster node at the same point of time). My wish would be to use the Quartz framework in the cluster mode (persisting the job status in the database
