Spring MVC Plugin Architecture

Question

I am a novice with JavaEE but have some experience with ASP.NET MVC. With ASP.NET MVC, I know we can make a plugin architecture with ASP.NET MVC web app so you can make a dll with MVC structure and put it into the existing ASP.NET MVC web app to make it work without compiling the web app. http://www.wynia.org/wordpress/2008/12/05/aspnet-mvc-plugins/

I wonder if this kind of architecture is possible with Spring MVC. For example, when I make a jar (or war) file with MVC structure and put it into existing Spring MVC web app, it should work without recompiling the web app. If this is possible, how can I achieve that? Any reference would be appreciated.

Answer 1

It is possible without recompiling, but probably not without restarting. You could create a .jar which you drop into the WEB-INF/lib directory. By using classpath scanning you should be able to deploy your new controllers on start-up. You can skip the view entirely and directly output data to the ServletResponse. Rendering a view from a jar may or may not be possible, I don't know.
