How to map Multiple controllers in Spring MVC

Question

I have two controllers in my Application; one is userController, where I have add, delete and update methods; the other one is studentController, where I also have add, delete and update methods.

All the mappings are same in my methods using @RequestMapping annotation in both controllers. I have one confusion: if we are passing the same action from the JSP, then how will the Dispatcher find the corresponding controller? If anybody could describe this using example will be appreciated.

Answer 1

You have to set a @RequestMapping annotation at the class level the value of that annotation will be the prefix of all requests coming to that controller,
for example:

you can have a user controller

@Controller
@RequestMapping("user")
public class UserController {

    @RequestMapping("edit")
    public ModelAndView edit(@RequestParam(value = "id", required = false) Long id, Map<String, Object> model) {
        ...
    }
}

and a student controller

@Controller
@RequestMapping("student")
public class StudentController {

    @RequestMapping("edit")
    public ModelAndView edit(@RequestParam(value = "id", required = false) Long id, Map<String, Object> model) {
        ...
    }
}

Both controller have the same method, with same request mapping but you can access them via following uris:

yourserver/user/edit
yourserver/student/edit
