Robospice ()未触发

Question

我有个奇怪的问题。我已经使用robopsice大约一个月了，它工作得很好，但是今天吃完午饭回来后，我的SpiceRequest的loadDataFromNetwork停止了调用。我不认为这是应用程序代码的问题，但我不确定其他人是否可以查看。我的sql api运行良好，并且可以在浏览器中正常工作。下面是我得到的错误，SpiceRequest和调用它的活动：

我的SpiceRequest类

public class SessionRequest extends SpringAndroidSpiceRequest<UserSession>
{
    public enum OPERATION {LOGIN,LOGOUT,SIGNUP};

    private User user = new User ();
    private boolean operation;
    private String token;
    OPERATION op = null;
    Session toSend = new Session();
    Config config = new Config();
    public SessionRequest(Session s,String tok, OPERATION op) 
    {
        super(UserSession.class);
        toSend = s;
        this.token = tok;
        this.op = op;
    }

    @Override
    public UserSession loadDataFromNetwork() throws Exception 
    {
        HttpHeaders headers = new HttpHeaders();
        RestTemplate restTemplate = new RestTemplate();
        restTemplate.getMessageConverters().add(new MappingJacksonHttpMessageConverter());
        ResponseEntity<UserSession> response = null;
        HttpEntity<?> postEntity;
        switch(op)
        {
            case SIGNUP:
                try{
                    User send = new User ();
                    send.setUsername(toSend.getEmail());
                    send.setPassword(toSend.getPassword());
                    send.setPasswordConfirmation(toSend.getPasswordConfirmation());
                    restTemplate.getMessageConverters().add(new MappingJacksonHttpMessageConverter());
                    //MultiValueMap<String, User> body = new LinkedMultiValueMap<String, User>();
                    //body.add("user", send);
                    postEntity = new HttpEntity<Object>(send,headers);
                    Log.i("Request", new Gson().toJson(postEntity.getBody()));
                    response = restTemplate.exchange(config.WEB_SERVICE_URL + "/users/", HttpMethod.POST,postEntity,UserSession.class);
                    Log.i("Response", new Gson().toJson(response));
            }
            catch (RestClientException e) {
                Log.d("REST", ((HttpStatusCodeException)e).getResponseBodyAsString());
            }
            break;


            case LOGIN:
                restTemplate.getMessageConverters().add(new MappingJacksonHttpMessageConverter());
                postEntity = new HttpEntity<Object>(toSend,headers);
                response = restTemplate.exchange(config.WEB_SERVICE_URL + "/sessions/", HttpMethod.POST,postEntity,UserSession.class);
                Log.d("Response", new Gson().toJson(response));
                break;

            case LOGOUT:
                headers.add("Authorization", "Token token=" +token);
                restTemplate.getMessageConverters().add(new MappingJacksonHttpMessageConverter());
                HttpEntity<?> deleteEntity = new HttpEntity<Object>(headers);
                response = restTemplate.exchange(config.WEB_SERVICE_URL+ "sessions/" + token, HttpMethod.DELETE,deleteEntity,UserSession.class);
                return(null);

        }

      UserSession resp = response.getBody();
      Log.d("request","connected");
      return (resp);
    }

    /**
     * This method generates a unique cache key for this request. In this case
     * our cache key depends just on the keyword.
     * @return
     */
    public String createCacheKey() {
        return "followers." + user;
    }
}

来自执行请求的活动的块：

 private void performRequest() 
    {
        SessionRequest request = new SessionRequest (getCurrentSession(),"",SessionRequest.OPERATION.LOGIN);
        lastRequestCacheKey = request.createCacheKey();
        spiceManager.execute(request, lastRequestCacheKey, DurationInMillis.ONE_MINUTE, new UserRequestListener());
    }

    public void callPerformRequest(){
        performRequest();
    }

@Override
protected void onSaveInstanceState(Bundle outState) {

    super.onSaveInstanceState(outState);
}

@Override
protected void onRestoreInstanceState(Bundle savedInstanceState) {
    super.onRestoreInstanceState(savedInstanceState);
    if (savedInstanceState.containsKey(KEY_LAST_REQUEST_CACHE_KEY)) {
        lastRequestCacheKey = savedInstanceState
            .getString(KEY_LAST_REQUEST_CACHE_KEY);
        spiceManager.addListenerIfPending(UserSession.class,
            lastRequestCacheKey, new UserRequestListener());
        spiceManager.getFromCache(UserSession.class,
            lastRequestCacheKey, DurationInMillis.ONE_MINUTE,
            new UserRequestListener());
    }

}



private class UserRequestListener implements RequestListener <UserSession> 
{
    @Override
    public void onRequestFailure(SpiceException e) 
    {
        TextView error = (TextView) findViewById(R.id.errorText);
        error.setTypeface(Typeface.createFromAsset(getAssets(), "fonts/MYRIADPRO-REGULAR.OTF"));
        error.setText("Invalid Username or Password");

    }

    @Override
    public void onRequestSuccess (UserSession returnedSession) 
    {
        if (returnedSession == null) 
        {
            return;
        }
        returnedSession.getUser().setToken(returnedSession.getSession().getAuthToken());
        Bundle b = new Bundle();
        b.putParcelable("user", returnedSession.getUser());
        Intent i = new Intent (MainActivity.this,Dashboard.class);
        i.putExtras(b);
        startActivity(i);
    }
}

}

通过调试，我可以看到我们构造了请求，并且到达了execute调用，但是loadDataFromNetwork()方法没有触发，过了一会儿它就转到了onRequestFailure。这可能是我的RoboSpice jar有问题吗？这真的很奇怪，它会突然停止工作。我甚至试着重启我的电脑。我唯一能想到的另一件事是，也许缓存以某种方式阻止了它。如有任何帮助，我们不胜感激！

谢谢
