未设置Alamofire参数

Question

在下面的代码中，我试图传递这4个参数，但是未发送“源”和“广告系列”。当呼叫在Controller.java由输出是

“电子邮件：MYemail用户名：MYusername来源：空广告系列：空”

任何帮助将不胜感激！

快捷代码：

var params = [String: AnyObject]()
params = ["email":"MYemail" as AnyObject,
          "username":"MYusername" as AnyObject,
          "source":"MYsource" as AnyObject,
          "campaign":"MYcamp" as AnyObject]

var url = "http://localhost:5000/makeCall"

Alamofire.request(url, method: .post, parameters: params, encoding: JSONEncoding.default, headers: headers).validate().responseJSON { response in
    print(" ==> jsonResone \(response)")
    let jsonResponse = JSON(response.result.value!)
    print(" ==> jsonResponse \(jsonResponse)")
}

后端Java代码：

Controller.java：

@RequestMapping(value = {"/makeCall"}, method = RequestMethod.POST , produces = MediaType.APPLICATION_JSON_VALUE , consumes = MediaType.APPLICATION_JSON_VALUE)
public ResponseEntity makeCall(@RequestBody MyModel myModel, HttpServletRequest request, HttpServletResponse response) throws ServiceException{

    System.out.println("email: "+myModel.getEmail()+" username: "+myModel.getUsername()+" source: "+myModel.getSource()+" campaign: "+myModel.getCampaign());

    ResponseEntity responseEntity = new ResponseEntity();
    responseEntity.setResponse("this is the response");
    responseEntity.setMessage("Success.");
    responseEntity.setSuccess(true);
    responseEntity.setStatusCode(200);

    return responseEntity;
}

MyModel.java：

public class MyModel {

    private String email;
    private String username;
    private String source;
    private String campaign;

    public String getEmail() {
        return email;
    }
    public void setEmail(String email) {
        this.email = email;
    }
    public String getUsername() {
        return username;
    }
    public void setUsername(String username){
        this.username = username;
    }
    public String getSource(){
        return source;
    }
    public void setSouce(String source){
        this.source = source;
    }
    public String getCampaign(){
        return campaign;
    }
    public void setCampaign(String campaign){
        this.campaign = campaign;
    }
}
