解密URL不工作

Question

的問題，我面對的是，當我把這個REST服務，我無法得到解密電子郵件：http://localhost:8080/RestWebService/MM/decryptEmail

更多細節我也低於添加圖像。 我希望我已經解釋了我的問題以及

喜謝謝你，我對於你們的盛情建議解決的問題。我想告訴你，如果我正在計算正確加密所需的時間：這是我的代碼

//   //**********AES Encryption 
      //checking time in msec 
      long startTime=System.currentTimeMillis(); 
      //System.out.println(startTime); 
      //   // Create key and cipher 
      SecretKey aesKey = KeysGeneration.getKeys(keypass); 

      Cipher cipher = Cipher.getInstance("AES"); 
      //    // encrypt the text 
      cipher.init(Cipher.ENCRYPT_MODE, aesKey); 
      byte[] encrypted = cipher.doFinal(email.getBytes()); 
      System.out.println("checking encryption "+new String(encrypted)); 

      BASE64Encoder encoder = new BASE64Encoder(); 
      email = encoder.encode(encrypted); 
      System.out.println("Encoded Encrypted Value="+email); 

      // text="&email="+URLEncoder.encode(new String(encrypted), "UTF-8"); 
      writer.write("&email="+email); 
      //Calculating Encryption Time 
      long stopTime = System.currentTimeMillis(); 
      Duration ms=Duration.ofMillis(stopTime); 

      //System.out.println(stopTime); 
      long elapsedTime = stopTime - startTime; 
      System.out.println("Time required for encryption (milliseconds)= "+elapsedTime);
