使用md5对密码字符串进行加密

 public static String md5(String message) {
  try {
   MessageDigest md = MessageDigest.getInstance("md5");
   byte[] md5 = md.digest(message.getBytes());
 

   BASE64Encoder encode = new BASE64Encoder();
   return encode.encode(md5);
  } catch (NoSuchAlgorithmException e) {
   throw new RuntimeException(e);
  }
 }
