Java Servlet Is the approach correct?

Question

Java

Hello, I'm learning Java EE and creating a client-server project in parallel. Where the client part is written in C #, and the server part in Java. For client interaction with the server, I use a servlet (interaction occurs through API commands in json format, not http request parameters).

Question: is the approach of using only one servlet that accepts the request, passes it to the appropriate modules for processing and then sends the response back?

Answer 1

If it is so convenient for you, in the form of a proxy servlet, then yes, the approach is normal. Yes, work through json is also normal. Don't forget that there are also different methods GET/PUT/POST/DELETE/UPDATE/HEAD etc. Very often they are the most convenient to manipulate. For example, by GET we take data, by POST - we transfer, by PUT - we update, by DELETE - we delete :-)
Well, in a large project it is still more convenient to divide servlets by data types.

Yes. It works in a similar way, for example DispatcherServletfrom Spring MVC :
