Java搭建微信公众号的服务器配置

代码文件：

package com.dhrtec.utils;

import java.security.MessageDigest;

import java.security.NoSuchAlgorithmException;

import java.util.Arrays;

/**

*/

public class SignUtil {

private static String token = Global.getConfig("WeChatToken");// 与微信公众号上的token一致

/**

* 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

*/

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;

}

}

调用方法：

@RequestMapping(value = "/serial", method = RequestMethod.GET)

public String checkSign(HttpServletRequest request,HttpServletResponse response){

String signature=request.getParameter("signature");

String timestamp=request.getParameter("timestamp");

String nonce=request.getParameter("nonce");

String echostr=request.getParameter("echostr");

System.out.println("本身"+signature);

if(SignUtil.checkSignature(signature,timestamp,nonce)) {

return echostr;

}

return null;

}
