'What is DDD's Aggregate in SpringBoot MVC?
Suppose I've a bunch of microservices, each written on SpringBoot MVC (REST, Controller, Service, etc..)
Can anybody explain what is DDD's Aggregate in SpringBoot MVC? is it a controller? Or is it a specific microservice which is a root for some other microservices?
In other words, is aggregate something within a service with a controller's endpoint as a root? or is aggregate a sub-set of microservices with a particular SpringBoot application/service as an entry point to them?

Two things here.
Spring MVC is a boundary layer to translate between HTTP and internals of the app. The internals are where all the DDD happens, not the boundary itself
Spring Boot is for bootstrapping an application with all the common tools and making a runnable deployment unit.
So, in case of DDD an HTTP request comes to Spring MVC layer, there a domain request is instantiated and passed to domain core for execution. Domain response then comes back and is translated into HTTP response by Spring MVC layer.
