AndroidのJsonObjectRequestのエラー500

Question

My ServerにJSONオブジェクトを送信中にエラー500が発生しました。私はデータベースにユーザーを保存する必要があるので、POSTメソッドを使用しています。出力が印刷されない（onResponseメソッドで）何かが間違っていると思っています。サーバー側では、データは印刷されませんが、例外は処理されず、エラーもありません。すべて正常に処理されますが、データはまだそこにはありません！

アンドロイドレジスタ方法：

public class RegisterIndividualActivity extends AppCompatActivity { 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_register_individual); 
     setListeners(); 
    } 

    private void setListeners() { 
     final EditText loginField = (EditText) findViewById(R.id.loginField); 
     final EditText passwordField = (EditText) findViewById(R.id.passwordField); 

     Button registerButton = (Button) findViewById(R.id.registerButton); 

     registerButton.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View v) { 
       register(
         loginField.getText(), 
         passwordField.getText(), 
       ); 
      } 
     }); 
    } 

    private void register(final Editable login, 
          final Editable password){ 
     final ProgressDialog progressDialog = new ProgressDialog(this); 
     progressDialog.setMessage("Creating new acc..."); 
     progressDialog.show(); 

     RequestQueue queueAcc = Volley.newRequestQueue(this); 
     String urlAcc = getResources().getString(R.string.server_address)+"android/user/register?login=" 
       + login.toString() + "&password=" + password.toString(); 


     JSONObject newUser = new JSONObject(); 
     try { 
      newUser.put("login", login.toString()); 
      newUser.put("password", password.toString()); 
     } catch (JSONException e) { 
      e.printStackTrace(); 
     } 
     System.out.println("USER TO SAVE: " + newUser.toString()); 
     JsonObjectRequest urlAccStringRequest = new JsonObjectRequest(Request.Method.POST, urlAcc, newUser, new Response.Listener<JSONObject>() { 
      @Override 
      public void onResponse(JSONObject response) { 
         System.out.println("Good morning " + login.toString()); //doesnt print 

        } 
       }, new Response.ErrorListener() { 
      @Override 
      public void onErrorResponse(VolleyError error) { //i got this error 
       progressDialog.dismiss(); 
       Toast.makeText(RegisterIndividualActivity.this, "Connection error", Toast.LENGTH_SHORT).show(); 
      } 
     }); 

     queueAcc.add(urlAccStringRequest); 

     queueAcc.start(); 
    } 
} 

サーバ側のコントローラ（これは@ControllerのadnotationとAndroid /ユーザである必要マッピングに適切なクラスである）：

@RequestMapping(value = "/register", method = RequestMethod.POST) 
public void register(
     @RequestParam("login") String login, 
     @RequestParam("password") String password, 
     HttpServletRequest request, HttpServletResponse response, Model model 
){ 
    System.out.println("\nIn Register method.."); 
    UserModel uM = new UserModel(); 
    HttpSession session = request.getSession(true); 
    response.setContentType("application/json"); 
    response.setCharacterEncoding("UTF-8"); 
    uM.setAccountType("Client"); 
    JsonParser parser = new JsonParser(); 
    try { 
     System.out.println("\nTrying to save.."); 
     JsonObject jsonObject = (JsonObject) parser.parse(request.getReader()); 
     System.out.println(jsonObject.get("login").toString()); //event this doesnt print 
     uM.setLogin(jsonObject.get("login").toString()); 
     uM.setPassword(jsonObject.get("password").toString()); 
     System.out.println(uM.toString()); //doesnt print 
     userDAO.save(uM); 
    } catch (IOException e) { // doesnt throw exception 
     e.printStackTrace(); 
    } 


    System.out.println(uM.toString()); // doesnt print 

}

@EDIT 2

これは、これにtry-catchブロックを変更した後、サーバーのログです：

try { 
     System.out.println("\nTrying to save.."); 
     JsonObject jsonObject = (JsonObject) parser.parse(request.getReader()); 
     System.out.println(jsonObject.get("login").toString()); //event this doesnt print 

    } catch (IOException e) { // doesnt throw exception 
     e.printStackTrace(); 
    }

@EDIT 3 !!!!それと間違って何

JsonObject jsonObject = (JsonObject) parser.parse(request.getReader()); 

：私は、この行がエラーをcousingされていることを考え出し

は、第2のサーバログにありましたか？

@EDIT 4

これはJSONを読み取るための私の現在のコードです：

try { 
      System.out.println("\nTrying to save..."); 
      InputStream inputStream = request.getInputStream(); 
      JsonReader reader = Json.createReader(inputStream); //this is were error is 
      reader.close(); 
//   JsonObject jsonObject = reader.readObject(); 
//   reader.close(); 
//   System.out.println(jsonObject.get("login").toString()); 
////   uM.setLogin(jsonObject.get("login").toString()); 
//   uM.setPassword(jsonObject.get("password").toString()); 
//   System.out.println(uM.toString()); 
//   userDAO.save(uM); 
     } catch (IOException e) { 
      e.printStackTrace(); 
     }

Answer 1

com.google.gson.JsonObject cannot be cast to javax.json.JsonObject

あなたは輸入しているようです編間違ったJsonObjectクラス

あなたはGsonを使用している場合、これはhow to parse JSON with it

JsonObject jsonObject = (JsonObject) parser.parse(request.getReader());
