How to secure a service REST with spring3?

I just made a we开发者_运维百科b service with spring 3 using MVC annotations (@Controller, @RequestMapping) and now I'm looking for a way to secure it. Does someone know how to do it?

Thanks,

I recommend this video to learn about Spring-Security. Ben Alex is the founder, so well qualified to teach it.

Disclaimer: while Spring-Security will provide some authentication and access control, it won't guarantee your system is secure!
