1.WeChatController

2.SignUtil

public class SignUtil {private static String token = "123321";// 与微信公众号上的token一致，是服务器令牌（token），这里写什么。服务器就填什么/*** 校验签名** @param signature 签名* @param timestamp 时间戳* @param nonce随机数* @return 布尔值*/public static boolean checkSignature(String signature, String timestamp, String nonce) {String checktext = null;if (null != signature) {//对ToKen,timestamp,nonce 按字典排序String[] paramArr = new String[]{token, timestamp, nonce};Arrays.sort(paramArr);//将排序后的结果拼成一个字符串String content = paramArr[0].concat(paramArr[1]).concat(paramArr[2]);try {MessageDigest md = MessageDigest.getInstance("SHA-1");//对接后的字符串进行sha1加密byte[] digest = md.digest(content.toString().getBytes());checktext = byteToStr(digest);} catch (NoSuchAlgorithmException e) {e.printStackTrace();}}//将加密后的字符串与signature进行对比return checktext != null ? checktext.equals(signature.toUpperCase()) : false;}/*** 将字节数组转化我16进制字符串** @param byteArrays 字符数组* @return 字符串*/private static String byteToStr(byte[] byteArrays) {String str = "";for (int i = 0; i < byteArrays.length; i++) {str += byteToHexStr(byteArrays[i]);}return str;}/*** 将字节转化为十六进制字符串** @param myByte 字节* @return 字符串*/private static String byteToHexStr(byte myByte) {char[] Digit = {'0', '1', '2', '3', '4', '5', '6', '7', '8', '9', 'A', 'B', 'C', 'D', 'E', 'F'};char[] tampArr = new char[2];tampArr[0] = Digit[(myByte >>> 4) & 0X0F];tampArr[1] = Digit[myByte & 0X0F];String str = new String(tampArr);return str;}}
