解决angular的$http.post()提交数据时后台接收不到参数值问题的方法

$.ajax({
  url:'/carlt/loginForm',
  method: 'POST',  
  data:{"name":"jquery","password":"pwd"},
  dataType:'json',
  success:function(data){
    //...
  }
});

@Controller
public class UserController {
  @ResponseBody
  @RequestMapping(value="/loginForm",method=RequestMethod.POST)
  public User loginPost(User user){
    System.out.println("username:"+user.getName());
    System.out.println("password:"+user.getPassword());
    return user;
  }
}
model（不要忘记get、set方法）：
public class User {
  private String name;
  private String password;
  private int age;
  
  //setter getter method

}

<div ng-app="myApp" ng-controller="formCtrl">
 <form novalidate>
 UserName:<br>
 <input type="text" ng-model="user.username"><br>
 PassWord:<br>
 <input type="text" ng-model="user.pwd">
 <br><br>
 <button ng-click="login()">登录</button>
 </form>
</div>

var app = angular.module('myApp', []);
app.controller('formCtrl', function($scope,$http) {
 $scope.login = function() {
  $http({
   url:'/carlt/loginForm',
   method: 'POST',   
   data: {name:'angular',password:'333',age:1}  
  }).success(function(){
   console.log("success!");
  }).error(function(){
   console.log("error");
  })
 };
});

var app = angular.module('myApp', []);
app.controller('formCtrl', function($scope,$http) {
  $scope.login = function() {
    $http({
      url:'/carlt/loginForm',
      method: 'POST',      
      data: {name:'angular',password:'333',age:1}   
    }).success(function(){
      console.log("success!");
    }).error(function(){
      console.log("error");
    })
  };
});
