        // 解密
  String DeString = AES.Decrypt(enString, cKey);
        System.out.println("解密后的字串是：" + DeString);
    }
}

PHP加解密方法：

public static function WeDecrypt($input, $securityKey) {
  $input = urldecode($input); 
  $input = openssl_decrypt($input, 'AES-128-ECB', $securityKey);    
  if (!$input) {
    return false;
   }  
   return $input; 
 }

public static function WeDoctorEncrypt($input, $securityKey) {
  
  $inputArr = json_decode($input, true);//转为数组
  if (!is_array($inputArr) || empty($inputArr)) {
    return false;
   }    
   $input = json_encode($inputArr, JSON_UNESCAPED_UNICODE);//转为json字符串   
   //进行Aes加密  
   $data = openssl_encrypt($input, 'AES-128-ECB', $securityKey);
    return urlencode($data); 
 }
