java - ajax POST + spring controller parameter passing error -

i have strange problem passing int param in post request spring mvc controller.

the thing parameter passed through post, didn't parsed controller.

here code: spring controller:

@controller @requestmapping("user") public class usercontroller {     @requestmapping(value = "/register", method = requestmethod.post)     @responsebody     public jsonresponse adduser(@requestbody user user){         system.out.println(user.getcondoid());         system.out.println(user.getpassword());         system.out.println(user.getusername());          *** stuff *** } 

user model:

public class user {     private string username;     private string password;     private int condo_id;     private list<string> roles;      public list<string> getroles() {         return roles;     }     public void setroles(list<string> roles) {         this.roles = roles;     }      public string getusername() {         return username;     }     public void setusername(string username) {         this.username = username;     }      public string getpassword() {         return password;     }     public void setpassword(string password) {         this.password = password;     }      public int getcondoid() {         return condo_id;     }     public void setcondoid(int condo_id) {         this.condo_id = condo_id;     } } 

how send post in angular(example):

$scope.choosencondo.id = "7"; var formdata = {     "username" : $scope.registeruser.email,     "password" : $scope.registeruser.password,     "condo_id" : parseint($scope.choosencondo.id) };  var req = {     method: 'post',     url: '/api/user/register',     headers: {         'x-csrf-token': $('input[name="_csrf"]').val(),         'upgrade-insecure-requests': "1",         //'content-type': "application/x-www-form-urlencoded"         'content-type': 'application/json'     },     data: formdata }  $http(req) 

so, system.out.println(user.getcondoid()); receive "0" in log. post data looks example: {"username":"4t654y54y54y","password":"1q2w3e","condo_id":2} param sent in post. can reason of trouble?

your user model should

public class user {     private string username;     private string password;     private int condo_id;     private list<string> roles;      public list<string> getroles() {         return roles;     }     public void setroles(list<string> roles) {         this.roles = roles;     }      public string getusername() {         return username;     }     public void setusername(string username) {         this.username = username;     }      public string getpassword() {         return password;     }     public void setpassword(string password) {         this.password = password;     }      public int getcondo_id() {         return condo_id;     }      public void setcondo_id(int condo_id) {         this.condo_id = condo_id;     }      /*     public int getcondoid() {         return condo_id;     }     public void setcondoid(int condo_id) {         this.condo_id = condo_id;     }     */ } 

it didn't find actual setter method set value property "condo_id".

so, system.out.println(user.getcondoid()); receive "0" in log.  

by java nature, primitive value default initialized 0, printing 0
