Configure as above, the code is as follows

@Controller @requestmapping (value= "user/") public class Usercontroller {@RequestMapping (value= "login") public @ Responsebody  Model Login (final model) {Model.addattribute ("1", "2"); return model;}}

With the model of this return, always mapped to the URL, I do not know where the problem, but also can return JSON. If any of the great gods come across, please help me look.
