阿里云短信签名机制实现[java]

公司要求用阿里云短信进行开发，由于网上教程比较少，先整理下代码，如下：

import java.io.UnsupportedEncodingException;

import java.net.URLEncoder;

import java.security.InvalidKeyException;

import java.security.NoSuchAlgorithmException;

import java.util.Arrays;

import java.util.Calendar;

import java.util.GregorianCalendar;

import java.util.HashMap;

import java.util.Map;

import javax.crypto.Mac;

import javax.crypto.spec.SecretKeySpec;

import sun.misc.BASE64Encoder;
