“still I am not sure whether this is realy the way to go”

Well it is the way to go and the old way is being deprecated in Spring 3.0.

A good articles on the topic is:

Even better is the slides from his presentation at Spring One 2008. They really help clarify things. I hope he puts them up on the web. Here you’re doing what he’s talking about and just adapting the annotations to the old style controllers. Works for backwards compatibility, but it’s not the best approach going forward.

Think of the @Controller as a MultiActionController with methods for the different associated methods. Combine it with the convention over configuration stuff like ControllerClassNameHandlerMapping and you get more restful URLs …/employee/show, …/employee/edit, …/employee/find which correspond to methods on an EmployeeController. I’ve definitely come around to his way of thinking. I’ll admit I was on the fence myself before I understood the new approach.

You saved my life! I spent all the day long trying to put the SpringMvc to work. Now it is just running well with the SessionAttribute…
Thanks for sharing this knowledge.

Check page 352 of the reference manual (2.5.1) section “13.12.3. Mapping requests with @RequestMapping”. You can add parameters to your method of type ServletRequest (or PortletRequest). There is also a special class from the springframework called WebRequest. I must admit I have not used it before, but is seems pretty easy.

good luck

Hi
How can I retreive the web request in the controler? let say I have the controller defined like this:
@Controller
@RequestMapping(“/*.hmtl”)
public class MyController{}

So I want to retrieve home.hml from the controller in case that ressource was required.

Thanks

I think you can (If I understand you correct). You can find more information in the reference documentation of the springmodules project. The annotation looks like this:

@Validator(PersonValidator.class)

You can do more advanced validations with this class. The easy validations on field level are done using other annotations. Check out the code, mainly the domain objects. There you can find examples like this:

@NotNull
@Length(min = 3, max = 50 )
private String name;

Great post on using Spring with annotations! Is it possible to declare a validation class with annotations?
