Spring MVC validation with Annotations

Question

I'm having quite some trouble since I migrated my controllers from classical inheritance to use the annotations like @Controller and @RequestMapping. The problem is that I don't know how to plug in validation like in the old case. Are there any good tutorials about this?

Answer 1

Have a look at §13.11.x of the Spring MVC documentation. It covers annotation-based controller configuration, including data binding. It should be very useful to you.

Good luck!

Answer 2

At a pinch, there's always this thing: http://annovalidator.sourceforge.net/ - it's all tooled around using annotations for validation, and is designed to work with Spring.

Answer 3

Spring 3 includes improved support for validation, and in particular, JSR-303 validation. You can validate form beans using the @Valid annotation and . See
