Spring Integration Migration from 3 to 4

Question

I have multiple services (serviceA, ServiceB ..)using spring integration . Each service is dependent upon other submodules(which again is using spring integration).

In most of our config xml files we have hard coded the version like below : http://www.springframework.org/schema/integration/ws http://www.springframework.org/schema/integration/ws/spring-integration-ws-3.0.xsd

I have a task to migrate one service (ServiceA) from spring integration 3 to 4. I changed the config files to use versionless aliases (e.g. spring-integration.xsd), but as this service is dependent on other services, it looks like I have to change all the dependent services also to spring integration 4.

Is there any other option ?

Answer 1

I'm afraid it isn't possible if the dependency is on the code level. Spring Integration 3.0 is compatible with Spring Framework 4.x, but only if you don't use Messaging. In that case an old org.springframework.integration.Message isn't compatible with new org.springframework.messaging.Message.

See more info about migration in the Migration Guide.
