Angular在浏览器中给出400错误请求

Question

I am getting a 400 Bad request while inserting values in the database. The new data is successfully inserted but in the browser it is giving bad request. For back end I am using Spring controller and mongoDB, using angularJs controller. Please see the below code for the same. Can anybody tell what is the problem ?

Spring controller code -

@RequestMapping(value="/users/update/{id}/{firstName}/{lastName}/{email}/{mobile}/{creation_time}/{status}",method = RequestMethod.POST,headers="Accept=application/json")
public List<User> updateUser(@PathVariable int id,@PathVariable String firstName,@PathVariable String lastName,@PathVariable String email,@PathVariable String mobile,@PathVariable long creation_time,@PathVariable String status) throws ParseException { 
             Date date = new Date(creation_time); 
             User user = new User();
               user.setFirstName(firstName);
               user.setLastName(lastName);
               user.setEmail(email);
               user.setMobile(mobile);
               user.setLast_update_time(new Date());
               user.setCreation_time(date);
               user.setStatus(status);
               userService.updateUserService(user);
             return userService.getAllUserService();
         }

Angular Js controller -

$scope.updateUser=function(user){           $http.post(urlBase+'users/update/'+user.id+'/'+user.firstName+'/'+user.lastName+'/'+user.email+'/'+user.mobile+'/'+user.creation_time+'/'+user.status)
                .success(function(data) {
                    $scope.users = data;
                     $scope.selected = {};
                }); 
        };

Answer 1

You're missing the annotation @ResponseBody in your method header. Try :

@RequestMapping(value="/users/update/{id}/{firstName}/{lastName}/{email}/{mobile}/{creation_time}/{status}",method = RequestMethod.POST,headers="Accept=application/json")
public @ResponseBody List<User> updateUser(.....){
    ....
}

I got the solution to this, was sending 'id' field in the path, have removed the same and it seems to be working fine. Thanks everyone all for your answers.
