Spring Web projects multi module

Question

Regarding modern multi-module constructions.

Can many Spring Web projects be imported into one another?

 - Project 1 ==> have some endpoints 
 - Project 2 ==> have some other
   endpoints

I tried, but only Project 1's endpoints are exposed. and the other project 2 endpoints provide the following error

 The origin server did not find a current representation for the target resource or is not
        willing to disclose that one exists.

Answer 1

I was expecting this will include project 2 packages as it's the main runner

@ComponentScan(basePackages="project1.*")

but, regrettably, it doesn't.

so it should be

@ComponentScan(basePackages="project1.*","project2.*")
