Spring Integration input channel for Service Activator

Question

I am learning Spring Integration and trying to build small small applications. I have been stuck in my new application. Actually I am trying to get data from 2 different table and compare them. For that i have created 2 different service which individuality are getting data from different different tables.

Now my question.

1. Can i use one gateway and one input channel for calling both the Service Activator which are calling my service methods.If not how shall i approach.

2. How shall i gather both the data for comparison. I mean to say. How shall i send data from 2 different service activator to One end point(say Aggregator) where i can compare.

Answer 1

You need to consider to use a Scatter-Gather component for this kind of tasks: https://docs.spring.io/spring-integration/docs/5.1.1.RELEASE/reference/html/messaging-routing-chapter.html#scatter-gather
