调用解密手机号接口，经常第一次失败，重新调用才会成功 解密代码如下： try { Cipher cipher = Cipher.getInstance("AES/CBC/PKCS7Padding");    Key sKeySpec = new SecretKeySpec(keyByte, "AES");    cipher.init(Cipher.DECRYPT_MODE, sKeySpec, generateIV(ivByte));// 初始化    byte[] result = cipher.doFinal(content);    return  new String(result,"UTF-8"); } catch (NoSuchAlgorithmException e) { e.printStackTrace(); } catch (NoSuchPaddingException e) { e.printStackTrace(); } catch (InvalidKeyException e) { e.printStackTrace(); } catch (IllegalBlockSizeException e) { e.printStackTrace(); } catch (BadPaddingException e) { e.printStackTrace(); } catch (NoSuchProviderException e) { // TODO Auto-generated catch block    e.printStackTrace(); } catch (Exception e) { // TODO Auto-generated catch block    e.printStackTrace(); }
