spring jpa embeddable class send int instead of Object

问题

I have a little problem between my RestController response and my AngularJs Controller.

First, I'm calling my rest webservice with $http :

myModule.controller('UserDetailsCtrl',function($http, idUser){

    var self = this;

    $http.post('/get-user-details', idUser).then(
        function(response){        

            self.clients = response.data.usersClients;

            for(client of self.clients){                    
                console.log("pkUsersClients : " + client.pkUsersClients); // console display "[object Object]"
                console.log("client : " + client.pkUsersClients.client); // console display "1" instead of User Object
                console.log("keys : " + Object.keys(client.pkUsersClients)); // console display "keys : user,client"
                console.log("name : " + client.pkUsersClients.client.name); // display "undefined"
            }

        },    function(){
            // error
        }
    );

});

Then, I have my spring @RestController :

@RestController
public class UserDetailsRest {

    @Autowired
    private UserDao userDao;

    @Autowired
    private UserDatasDao userDatasDao;

    @Autowired
    private UsersClientsDao usersClientsDao;

    @RequestMapping("get-user-details")
    public UserDetailsDto getUserDetails(@RequestBody Long idUser){

        User user = userDao.findByIdUser(idUser);

        UserDatas userDatas = userDatasDao.findByIdUser(user);

        List<UsersClients> usersClients = usersClientsDao.findByPkUsersClientsUser(user);

        UserDetailsDto userDetailsDto = new UserDetailsDto(userDatas, usersClients);

        return userDetailsDto; 
        // userDetailsDto contains : List<UsersClients> (2 lines). In each line, UsersClients contains : UserClientId pkUsersClients. Which contains : User + Client.
        // But in Angular, User and Client are int and int (the id in fact).

    }

}

So, my issue is that :

my webservice return an object UserDetailsDto which contains:

private List usersClients;
each UsersClients in this List contains :

private List usersClients;

private UserClientId pkUsersClients
pkUsersClients is a @Embeddable Object which contains :

private User user;

private Client client;
in angularjs, User and Client are not Object but int.

My classes :

my DTO which is the response

public class UserDetailsDto {

    private List<UsersClients> usersClients;

    public UserDetailsDto(List<UsersClients> _usersClients) {
        super();
        this.usersClients = _usersClients;
    }

    // getters/setters
    // toString override

}

My association table :

@Entity
@Table(name="users_clients")
@AssociationOverrides(
    {
        @AssociationOverride(
            name="pkUsersClients.user",
            joinColumns = @JoinColumn(name="id_user")
        ),
        @AssociationOverride(
            name="pkUsersClients.client",
            joinColumns = @JoinColumn(name="id_client")        
        )
    }
)
public class UsersClients {

    private UserClientId pkUsersClients = new UserClientId();

    @Temporal(TemporalType.DATE)
    private Date date_begin;

    @EmbeddedId
    public UserClientId getPkUsersClients() {
        return pkUsersClients;
    }

    public void setPkUsersClients(UserClientId pkUsersClients) {
        this.pkUsersClients = pkUsersClients;
    }

    @Transient
    public User getUser() {
        return getPkUsersClients().getUser();
    }

    public void setUser(User user) {
        getPkUsersClients().setUser(user);
    }

    @Transient
    public Client getIdClient() {
        return getPkUsersClients().getClient();
    }

    public void setIdClient(Client client) {
        getPkUsersClients().setClient(client);
    }

    public Date getDate_begin() {
        return date_begin;
    }

    public void setDate_begin(Date date_begin) {
        this.date_begin = date_begin;
    }

}

to finish, my embeddable class :

@Embeddable
public class UserClientId implements Serializable{

    private static final long serialVersionUID = 1L;

    private User user;
    private Client client;

    /**
     * @return the user
     */
    @ManyToOne(cascade=CascadeType.ALL)
    public User getUser() {
        return user;
    }

    /**
     * @param user the user to set
     */
    public void setUser(User user) {
        this.user = user;
    }

    /**
     * @return the client
     */
    @ManyToOne(cascade=CascadeType.ALL)
    public Client getClient() {
        return client;
    }

    /**
     * @param client the client to set
     */
    public void setClient(Client client) {
        this.client = client;
    }
}

EDIT : With chrome developper tools, I can see that client = "1" BUT user is an object. Now, the problem is that my response contains :

{
  "avatar": null,
  "identity": "M. edith USER",
  "login": "EditUser",
  "address": "125, rue du test. testLand (testLand)",
  "email": "john.doe@gmail.com",

                  "logo": "iVBORw0KGgoAAAANSUhEUgAAAG..."
                }
              },

            {

                "user": 31,
                "client": {
                  "idClient": 1,
                  "name": "AAAAAA",

                  "logo": "/9j/4QDCRXhpZgAASUkqAAgAAAAHABIBAwABA..."
                }
              },
              "date_begin": null,
              "date_end": null,
              "enable": false,
              "user": 31,
              "idClient": 1
            }
          ]
        },
        "client": 1
      },
      "date_begin": null,
      "date_end": null,
      "enable": false,
      "user": 31,
      "idClient": 1
    },
    {
      "pkUsersClients": {
        "user": 31,
        "client": 1
      },
      "date_begin": null,
      "date_end": null,
      "enable": false,
      "user": 31,
      "idClient": 1
    },
    {
      "pkUsersClients": {
        "user": 31,
        "client": 5
      },
      "date_begin": 1464818400000,
      "date_end": 1467237600000,
      "enable": false,
      "user": 31,
      "idClient": 5
    }
  ]

You can see that it is a little disturbing :/

Please, give me some help, I don't understand where I make a mistake. Thanks in advance.
