How to access HttpServletResponse in Spring Component?

Question

I have a spring-boot app with swagger code generator. Since the controllers are autogenerated from swagger yaml I don't think I can modify the controllers to access the HttpServletResponse.

Is there a way to access the HttpServletResponse from a class annotated with @Component?

I am trying to access the HttpServletResponse instance in order to set a cookie.

If you don't want to touch the controller at all would be to make your bean a spring filter bean. This article here gives you details how to declare such bean. Once declare you need to bind it to url pointing to your controller method.

It depends on What your final goal is.
