使用JSP MVC的单页应用程序

Question

I'm pretty new to Angular and jsp and I have a question about general architecture of a single-page system. I understand that jsp mvc has it's own security features that some of course related to conditionally delivering static/dynamic pages to the clients.

How can that feature work with Angular? Obviously in a single page application, working with partials, the server does not need to pass pages to the client.

My specific question is about the login page. Do I need to separate my login html from my main 'single-page' index.html with all my routes? Will I have a 'login.jsp' file which is a stand-alone file handled by jsp and only after login routing to the single-page part of the application?

Thanks!!!

Answer 1

Regarding the login part:

My recommendation is that as an application developer you should not be thinking in how to implement your login page. This would bind your application to a specific authentication mechanism, and its a sign of getting into troubles (implementing the whole app security by your own)

It is preferable that this binding is performed in a pluggable (declarative) way, like it is done in JEE by the container or in Spring security by a dedicated framework.

So answering your question: you should no have a login.jsp at all, this page would be automatically generated once you have properly configured your application security with a 'login form' authentication mechanism. (Both JEE and Spring provide also mechanisms for customizing this pages).

The framework/container would intercept the request to your web app, identify if the user is authenticated, redirect to the login page and finally redirect to the original url, if authentication succeeds.
