You would follow the MVC pattern for each Spring Boot application you want to deploy on the servers. I recommend this [LINK] tutorial. Your Angular application would send HTTP requests for the corresponding SpringBoot application's endpoint (app1/getUsers) for example. Check here [this video] . You can use the classic Servlet architecture with the synchronous blocking module of thread per request. Or, you can use Spring's new Reactor stack for asynchronous handling of requests. Check here [LINK] for comparison.

I am following a tutorial on how to do a login authentication using spring security and angular but whenever I'm running the angular program and try to login I get a 401 error. I feel like it's a cors issue and created a cors filter class which was a solution to a similar question but i'm still getting the same error. The login details are correct as I use the same credentials to login to localhost:8080 for the backend but when I try to login using the front-end I get the following error in the index. Error: Request URL: [LINK] Request Method: GET Status Code: 401 Remote Address: [::1]:8080 Referrer Policy: no-referrer-when-downgrade Access-Control-Allow-Headers: access_token, authorization,
