MD5 / SHA 加密 ， 和 url参数的值有中文问题

MD5摘要：

/**
     * MD5加密
     * @param str
     * @return
     */
     public static String encode(String str) {
            MessageDigest digest;
            try {
                digest = MessageDigest.getInstance("MD5");
                try {
                    digest.update(str.getBytes("utf-8"));
                } catch (UnsupportedEncodingException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }
                return new BigInteger(1, digest.digest()).toString(16);
            } catch (NoSuchAlgorithmException e) {
                e.printStackTrace();
                return null;
            }
        }

解决url参数的值有中文：

    
     /**
      * 解决url参数的值有中文
      * @param url
      * @return
      * @throws UnsupportedEncodingException
      */
        public static String constructParam(String url) throws UnsupportedEncodingException{
            StringBuilder sb = new StringBuilder("");
            if(url == null) {
                return url;
            }else {
                String[] entry = url.split("&");
                for(int i=0;i<entry.length;i++) {
                    String key = entry[i].split("=")[0];
                    String value = entry[i].split("=")[1];
                    String encodeValue = URLEncoder.encode(value, "UTF-8");
                    sb.append(key).append("=").append(encodeValue).append("&");
                }
            }
            
            return sb.toString().substring(0, sb.lastIndexOf("&"));
        }
