解密URL不工作

Question

的问题，我面对的是，当我把这个REST服务，我无法得到解密电子邮件：http://localhost:8080/RestWebService/MM/decryptEmail

更多细节我也低于添加图像。 我希望我已经解释了我的问题以及

喜谢谢你，我对于你们的盛情建议解决的问题。我想告诉你，如果我正在计算正确加密所需的时间：这是我的代码

//   //**********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);
