Spring MVC design help

[Ravi Shankar Mukkavilli]

Hello All,

I'm new to Spring MVC and trying out a simple project.It will contain a simple adding, viewing, updating and deleting user work flows. It will have login page and once authenticated the user will be taken to a welcome screen which will have links to add, view, update and delete users. Clicking on any of the links will take to individual pages where the user can do the specific tasks. What I'm doing here is, I'm using a MultiActionController to group together all requests related to User work flow. As the user cannot directly access the addUser.jsp file which is inside the WEB-INF folder, so the request from "Add User" link will handled by the addUser method in the UserController which will redirect the user to the "Add User" page, and the user can then fill in the details and save the new user. Now here is where I'm getting confused. Where should I put the save process of the new user, should I put that in new method inside UserController, or use the same "addUser" method. What is the best way to handle this kind of scenario. Can you provide me with some sample code. Thanks

I hope I was able to clear my question.

I would make separate methods for each action. For example, one called "show", which would show the form, and one called "save", used to save to information.

If you started learning Struts, the developing a simple CRUD application wouldn't be a problem.

Better you avoid MultiActionController and stickwith Annotations to map the methods with corresponding to the path.

Thanks guys.

@Rajkumar: I don't have much idea about Spring annotations, but I'm interested in trying it. Can you direct me to a simple example. I did wrote a SimpleFormController (without annotations) in which I configured the Command name ,class, the form view and success view in the constructor something like this

   
public LoginController(){
        setCommandName("employee");
        setCommandClass(Employee.class);
        setFormView("login");
        setSuccessView("welcome");
    }

Can you provide me with a sample code/tutorial for the about code in annotations. Thanks for your help.

Ravi

You'll find some examples in the official reference.

Although christopher provide the link, i'll post a simple equivalent code for yours.

@RequestMapping(name=RequestMethod.POST)
public ModelAndView doThis(Employee emp)
{
 List<Employee> arg = someService.callMethod(emp);
 return new ModelAndView("success","passthis",arg);
}
