配置服务器 提示验证token失败 【已解决】

最近在学习微信小程序，遇到的第一个问题就是需要配置服务器

关于这个服务器的配置我也是绕了好多弯路，说白了腾讯就是想通过你填的这个URL和Token去验证你有一个自己的服务器(外网可以访问的服务器)，其实就是想让你证明你是你自己，呵呵....
关于这个token随便填不要纠结，下面直接看JAVA代码

package com.base.action;

import java.io.PrintWriter;
import java.security.MessageDigest;
import java.security.NoSuchAlgorithmException;
import java.util.Arrays;
import java.util.Enumeration;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.apache.log4j.Logger;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

@RequestMapping("/wechat")
@Controller
public class WechatController {
    private static Logger logger = Logger.getLogger(WechatController.class);
     
    private static String token = "xuejp";
 
    @RequestMapping(value = "/wx.do")
    public void get(HttpServletRequest request, HttpServletResponse response) throws Exception {
        System.out.println("========WechatController========= ");
        logger.info("-----来自微信的请求----");
 
        Enumeration pNames = request.getParameterNames();
        while (pNames.hasMoreElements()) {
            String name = (String) pNames.nextElement();
            String value = request.getParameter(name);
            //查看微信的请求都带了哪些参数
            String log = "name =" + name + "     value =" + value;
            logger.error(log);
        }
 
        String signature = request.getParameter("signature");/// 微信加密签名
        String timestamp = request.getParameter("timestamp");/// 时间戳
        String nonce = request.getParameter("nonce"); /// 随机数
        String echostr = request.getParameter("echostr"); // 随机字符串
        PrintWriter out = response.getWriter();
 
        if (checkSignature(signature, timestamp, nonce)) {
            out.print(echostr);
        }
 
        out.print(token);
 
        out.close();
        out = null;
 
    }
    
    /**
     * 校验签名
     */
    public static boolean checkSignature(String signature, String timestamp, String nonce) {
        System.out.println("signature:" + signature + "timestamp:" + timestamp + "nonc:" + nonce);
        String[] arr = new String[] { token, timestamp, nonce };
        // 将token、timestamp、nonce三个参数进行字典序排序
        Arrays.sort(arr);
        StringBuilder content = new StringBuilder();
        for (int i = 0; i < arr.length; i++) {
            content.append(arr[i]);
        }
        MessageDigest md = null;
        String tmpStr = null;
 
        try {
            md = MessageDigest.getInstance("SHA-1");
            // 将三个参数字符串拼接成一个字符串进行sha1加密
            byte[] digest = md.digest(content.toString().getBytes());
            tmpStr = byteToStr(digest);
        } catch (NoSuchAlgorithmException e) {
            e.printStackTrace();
        }
 
        content = null;
        // 将sha1加密后的字符串可与signature对比，标识该请求来源于微信
        System.out.println(tmpStr.equals(signature.toUpperCase()));
        return tmpStr != null ? tmpStr.equals(signature.toUpperCase()) : false;
    }
 
    /**
     * 将字节数组转换为十六进制字符串
     * 
     * @param byteArray
     * @return
     */
    private static String byteToStr(byte[] byteArray) {
        String strDigest = "";
        for (int i = 0; i < byteArray.length; i++) {
            strDigest += byteToHexStr(byteArray[i]);
        }
        return strDigest;
    }
 
    /**
     * 将字节转换为十六进制字符串
     * 
     * @param mByte
     * @return
     */
    private static String byteToHexStr(byte mByte) {
        char[] Digit = { '0', '1', '2', '3', '4', '5', '6', '7', '8', '9', 'A', 'B', 'C', 'D', 'E', 'F' };
        char[] tempArr = new char[2];
        tempArr[0] = Digit[(mByte >>> 4) & 0X0F];
        tempArr[1] = Digit[mByte & 0X0F];
 
        String s = new String(tempArr);
        return s;
    }
}

将以上代码部署到服务器上就可以了，在微信配置界面点击提交就会显示提交成功了，提交成功后一定要点击右上方的启用按钮
