发布带有角度2到jee json网络服务的表单数据

Question

我正在尝试使用Angular 2中的Http post方法发布我的表单数据，并在Java EE后端Web服务中接收该数据，因此这是我UserComponent的代码：

  export class UserComponent{
  form : FormGroup;
  output: string ;
  public pro: Client[]=[];
 constructor(private http: Http,public fb: FormBuilder,private ClientService: ClientService) {
this.form=this.fb.group({
  userName : '',
  password : '',
  nom : '',
  email : '',
  phone : '',
  adress : '',

});

}

这是我UserComponent的模板代码：

<md-card>
<form [formGroup]="form" class="form-group">
<md-input placeholder="Name" formControlName="name"></md-input><br>
<md-input placeholder="userEmail" formControlName="email"></md-input><br>
  <md-input placeholder="userPhone" formControlName="phone"></md-input><br>
<md-input placeholder="username" formControlName="userName"></md-input><br>
<md-input placeholder="shippingAddress" formControlName="adress"></md-input><br>
<md-input placeholder="password" formControlName="password"></md-input><br>
</form>

<md-card>
<button (click)="onSubmit(form.value);" md-raised-button ">Create User</button>
</md-card>

代表userService：

  sendInfo(value){
const body = new URLSearchParams(value);
body.set('Email', value.email);
body.set('name', value.name);
body.set('Address', value.adress);
body.set('Phone', value.phone);
body.set('password', value.password);
body.set('username', value.userName);

let headers = new Headers();
//headers.append('Content-Type', 'application/json');
headers.append('Content-Type', 'application/x-www-form-urlencoded');
return this.http.post('http://localhost:8080/BCWEB/AddUser',body.toString(), {
  headers : headers
}).map(res => res.json());

}

现在为后端Java EE Web服务：

    @POST
    @Path("/AjouterClient")
    @Consumes("application/x-www-form-urlencoded")
    public void post(
        @FormParam(value="Clientnom")String nom ,
        @FormParam(value="ClientEmail")String email,
        @FormParam(value="ClientPhone")String tel ,
        @FormParam(value="username")String adress ,
        @FormParam(value="password")String username ,
        @FormParam(value="shippingAddress")String password) {

     metier.ajouterClient(new     Client(nom,email,tel,username,password,adress));

       }
