Deployment error while using Spring Integration with Spring MVC - spring

Question

I had done a poc on SI in a spring boot application where I was able to send and receive mesages from TcpOutBoundGateway. Now I'm trying to merge my sample spring integration module to my actual enterprise spring application.
To do this, I added spring-integration.xml in the enterprise application and imported it in spring-core.xml
<import resource="classpath:rx/spring-integration.xml" />
Also added, spring-integration-ip and spring-integration-core to build.gradle file.
In my service class, autowired my SI bean
<bean id="rxService" class="com.api.services.RxService"/>
which will create payload to be sent to gateway as well as receive the response and parse the result and return the model object.
But on starting tomcat, I am getting the below error.

Here is my SI configuration, which is a request response model, where the client is my application

FYI - We are using a common jar, which has a bean named buildDetails with a property - apiVersion. It's gradle multiflat project and the module I'm working on has a buildDetails.properties files which has a key-apiVersion and value.
Now the confusing part is - I get this deployment error only if I just import SI xml in spring-core.xml, don't even have to autowire its service bean.
It would be helpful if you could validate the steps I have done to integrate SI into my application is correct.

Answer 1

The web context is a child of the root application context; if the properties are in the web context, beans in the root context can't use them.
Move the properties to the root context so they are visible to both.
