title: Run a same Spring boot Project with multiple server context path
body: <p>Hi Spring Boot Experts,
   I am trying to run/build a spring boot project in such a way that it can run under multiple context paths (localhost:8080/external-portal &amp; localhost:8081/internal-portal ).I have a application like internal &amp; external portal, Code is exactly same for both applications with some conditional checks in the code to differentiate between internal &amp; external app.I don't want to duplicate code base, but both applications will run as separate instance on different ports like localhost:8080/external-portal &amp; localhost:8081/internal-portal.I have idea about maven overlays, but it seems they wont work with spring boot.</p>
