import com.util.QuickWriter;
import com.thoughtworks.xstream.io.HierarchicalStreamWriter;
import com.thoughtworks.l.PrettyPrintWriter;
import com.thoughtworks.l.XppDriver;
import com.winxin.pojo.Article;
import com.winxin.pojo.MusicMessage;
import com.winxin.pojo.NewsMessage;
import com.winxin.pojo.TextMessage;
import org.dom4j.Document;
import org.dom4j.Element;
import org.dom4j.io.SAXReader;import javax.servlet.http.HttpServletRequest;
import java.io.InputStream;
import java.io.Writer;
import java.util.HashMap;
import java.util.List;
import java.util.Map;/*** 微信事件消息处理* @author cdj* @date 2018年8月3日 上午9:26:27*/
public class MessageUtil {/*** 解析微信发来的请求（XML）* * @param request* @return* @throws Exception*/public static Map<String, String> parseXml(HttpServletRequest request) throws Exception {// 将解析结果存储在HashMap中Map<String, String> map = new HashMap<String, String>();// 读取输入流SAXReader reader = new SAXReader();// 从request中取得输入流InputStream inputStream = InputStream();Document document = ad(inputStream);// 得到xml根元素Element root = RootElement();// 得到根元素的所有子节点@SuppressWarnings("unchecked")List<Element> elementList = root.elements();// 遍历所有子节点for (Element e : elementList) {map.Name(), e.getText());}// 释放资源inputStream.close();inputStream = null;return map;}/*** 文本消息对象转换成xml* * @param textMessage*            文本消息对象* @return xml*/public static String textMessageToXml(TextMessage textMessage) {xstream.alias("xml", Class());XML(textMessage);}/*** 音乐消息对象转换成xml* * @param musicMessage*            音乐消息对象* @return xml*/public static String musicMessageToXml(MusicMessage musicMessage) {xstream.alias("xml", Class());XML(musicMessage);}/*** 图文消息对象转换成xml* * @param newsMessage*            图文消息对象* @return xml*/public static String newsMessageToXml(NewsMessage newsMessage) {xstream.alias("xml", Class());xstream.alias("item", new Article().getClass());XML(newsMessage);}/*** 扩展xstream，使其支持CDATA块* */private static XStream xstream = new XStream(new XppDriver() {public HierarchicalStreamWriter createWriter(Writer out) {return new PrettyPrintWriter(out) {// 对所有xml节点的转换都增加CDATA标记boolean cdata = true;@Overrideprotected void writeText(QuickWriter writer, String text) {if (cdata) {writer.write("<![CDATA[");writer.write(text);writer.write("]]>");} else {writer.write(text);}}};}});}

6、消息类型

package com.winxin.util;public enum MsgType {text("文本"),image("图片"),location("地理位置"),link("连接"),event("事件"),news("图文信息") ;private String value;public String getValue() {return value;}private MsgType(String value) {this.value = value;}
}

7、信任管理器

package com.winxin.util;import javax.ssl.X509TrustManager;
import CertificateException;
import X509Certificate;/*** 描述: 信任管理器** @description* @time 2019/3/18*/
public class MyX509TrustManager implements X509TrustManager {/*** 检查客户端证书** @param chain* @param authType* @throws CertificateException*/@Overridepublic void checkClientTrusted(X509Certificate[] chain, String authType) throws CertificateException {}/*** 检查服务器端证书** @param chain* @param authType* @throws CertificateException*/@Overridepublic void checkServerTrusted(X509Certificate[] chain, String authType) throws CertificateException {}/*** 返回受信任的X509证书数组** @return*/@Overridepublic X509Certificate[] getAcceptedIssuers() {return null;}
}

8、请求校验工具类

package com.winxin.util;import java.security.MessageDigest;
import java.security.NoSuchAlgorithmException;/*** 请求校验工具类*/
public class SignUtil {// 与公众接口配置信息中的Token要一致private static String token = "wsx";public static boolean checkSignature(String signature, String timestamp, String nonce) {// 从请求中（也就是微信服务器传过来的）拿到的token, timestamp, nonceString[] arr = new String[] { token, timestamp, nonce };// 将token、timestamp、nonce三个参数进行字典序排序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 = Instance("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.String().getBytes());// 将字节数组转成字符串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return tmpStr != null ? tmpStr.UpperCase()) : false;}// 将加密后的字节数组变成字符串private static String byteToStr(byte[] byteArray) {String strDigest = "";for (int i = 0; i < byteArray.length; i++) {strDigest += byteToHexStr(byteArray[i]);}return strDigest;}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;}// 用于字典排序public static void sort(String a[]) {for (int i = 0; i < a.length - 1; i++) {for (int j = i + 1; j < a.length; j++) {if (a[j]pareTo(a[i]) < 0) {String temp = a[i];a[i] = a[j];a[j] = temp;}}}}
}

四、微信公众号请求项目的主要controller

package ller;import com.alibaba.fastjson.JSON;
import com.winxin.util.SignUtil;
import com.wx.service.WxEventService;
import org.apachemons.logging.Log;
import org.apachemons.logging.LogFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
import java.io.PrintWriter;
import java.util.Map;/*** 微信相关接口* * @author cdj**/
@Controller
@RequestMapping("/WxUser")
public class WxUserController {@Autowiredprivate WxEventService wxEventService;private static final Log LOG = Log(WxUserController.class);@RequestMapping("/HandleWxEvent")public void HandleWxEvent(HttpServletRequest req, HttpServletResponse resp) throws IOException {req.setCharacterEncoding("UTF-8");resp.setCharacterEncoding("UTF-8");Map<String, String[]> parameterMap = ParameterMap();System.out.println("requestData:" + JSONString(parameterMap));LOG.info("requestData:" + JSONString(parameterMap));// 微信加密签名String signature = Parameter("signature");// 时间戳String timestamp = Parameter("timestamp");// 随机数String nonce = Parameter("nonce");// 随机字符串String echostr = Parameter("echostr");System.out.println("signature=" + signature + ";timestamp=" + timestamp + ";nonce=" + nonce + ";echostr=" + echostr);LOG.info("signature=" + signature + ";timestamp=" + timestamp + ";nonce=" + nonce + ";echostr=" + echostr);PrintWriter out = Writer();// 通过检验signature对请求进行校验，若校验成功则原样返回echostr，表示接入成功，否则接入失败LOG.info("checkSignature:" + SignUtil.checkSignature(signature, timestamp, nonce));System.out.println("checkSignature:" + SignUtil.checkSignature(signature, timestamp, nonce));// 首次请求申请验证,返回echostrif (echostr != null) {out.println(echostr);if (out != null) {out.close();}return;}if (SignUtil.checkSignature(signature, timestamp, nonce)) {System.out.println("success");LOG.info("success");String message = "success";try {message = wxEventService.processRequest(req);} catch (Exception e) {e.printStackTrace();} finally {out.println(message);if (out != null) {out.close();}}} else {System.out.println("The request signature is invalid");LOG.info("The request signature is invalid");}}}

五、还有一个定时任务，因为token的有效期只有7200秒

package com.wx.util;import com.winxin.util.CommonUtil;
import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Component;/*** 创建定时任务实现类* @description* @time 2019/3/19*/
@Component
public class ScheduledTasks {/*** 每7100秒执行一次*/@Scheduled(fixedRate = 7100000)public void reportCurrentTime() {//这个调用的是上面工具类的第一个类中的获取token的方法Token();}}

六、
1、serviceImpl层(自己写一下service)

package com.wx.service.impl;import com.winxin.pojo.Article;
import com.winxin.pojo.NewsMessage;
import com.winxin.pojo.TextMessage;
import com.winxin.util.EventConstant;
import com.winxin.util.MessageUtil;
import com.wx.service.WxEventService;
import org.springframework.stereotype.Component;
import org.springframework.stereotype.Service;import javax.servlet.http.HttpServletRequest;
import java.util.ArrayList;
import java.util.List;
import java.util.Map;/*** @className:WxEventServiceImpl* @description: TODO* @author: WX* @date: 2019-03-20 13:01*/
@Component
@Service
public class WxEventServiceImpl implements WxEventService {@Overridepublic String processRequest(HttpServletRequest req) {String respMessage = null;try {// 默认返回的文本消息内容String respContent = "请求处理异常，请稍候尝试！";// xml请求解析Map<String, String> requestMap = MessageUtil.parseXml(req);// 发送方帐号（open_id）String fromUserName = ("FromUserName");// 公众帐号String toUserName = ("ToUserName");// 消息类型String msgType = ("MsgType");// 回复文本消息TextMessage textMessage = new TextMessage();textMessage.setToUserName(fromUserName);textMessage.setFromUserName(toUserName);textMessage.setCreateTime(System.currentTimeMillis());textMessage.setMsgType(EventConstant.RESP_MESSAGE_TYPE_TEXT);textMessage.setFuncFlag(0);// 文本消息if (msgType.equals(EventConstant.RESP_MESSAGE_TYPE_TEXT)) {respContent = "您发送的是文本消息！";}// 图片消息else if (msgType.equals(EventConstant.REQ_MESSAGE_TYPE_IMAGE)) {respContent = "您发送的是图片消息！";}// 地理位置消息else if (msgType.equals(EventConstant.REQ_MESSAGE_TYPE_LOCATION)) {respContent = "您发送的是地理位置消息！";}// 链接消息else if (msgType.equals(EventConstant.REQ_MESSAGE_TYPE_LINK)) {respContent = "您发送的是链接消息！";}// 音频消息else if (msgType.equals(EventConstant.REQ_MESSAGE_TYPE_VOICE)) {respContent = "您发送的是音频消息！";}// 事件推送else if (msgType.equals(EventConstant.REQ_MESSAGE_TYPE_EVENT)) {// 事件类型String eventType = ("Event");// 订阅if (eventType.equals(EventConstant.EVENT_TYPE_SUBSCRIBE)) {respContent = "谢谢您的关注！";}// 取消订阅else if (eventType.equals(EventConstant.EVENT_TYPE_UNSUBSCRIBE)) {// 取消订阅后用户再收不到公众号发送的消息，因此不需要回复消息}// 自定义菜单点击事件else if (eventType.equals(EventConstant.EVENT_TYPE_CLICK)) {// 事件KEY值，与创建自定义菜单时指定的KEY值对应String eventKey = ("EventKey");if (eventKey.equals("11")) {respContent = "天气预报菜单项被点击！";} else if (eventKey.equals("12")) {respContent = "公交查询菜单项被点击！";} else if (eventKey.equals("13")) {respContent = "周边搜索菜单项被点击！";} else if (eventKey.equals("14")) {respContent = "历史上的今天菜单项被点击！";} else if (eventKey.equals("21")) {respContent = "歌曲点播菜单项被点击！";} else if (eventKey.equals("22")) {respContent = "经典游戏菜单项被点击！";} else if (eventKey.equals("23")) {respContent = "美女电台菜单项被点击！";} else if (eventKey.equals("24")) {respContent = "人脸识别菜单项被点击！";} else if (eventKey.equals("25")) {//聊天唠嗑菜单项被点击NewsMessage newsMessage = new NewsMessage();newsMessage.setToUserName(fromUserName);newsMessage.setFromUserName(toUserName);newsMessage.setCreateTime(System.currentTimeMillis());newsMessage.setMsgType(EventConstant.RESP_MESSAGE_TYPE_NEWS);newsMessage.setFuncFlag(0);List<Article> articleList = new ArrayList<Article>();Article article = new Article();article.setTitle("我是一条单图文消息");article.setDescription("我是描述信息，哈哈哈哈哈哈哈。。。");article.setPicUrl(".jpg");article.setUrl("");articleList.add(article);//多图文的话,新建多个article 放入articleList 中即可实现// 设置图文消息个数newsMessage.setArticleCount(articleList.size());// 设置图文消息包含的图文集合newsMessage.setArticles(articleList);// 将图文消息对象转换成xml字符串respMessage = wsMessageToXml(newsMessage);return respMessage;} else if (eventKey.equals("32")) {respContent = "会员中心菜单项被点击！";} else if (eventKey.equals("33")) {respContent = "注册会员菜单项被点击！";}}}textMessage.setContent(respContent);respMessage = MessageToXml(textMessage);return respMessage;} catch (Exception e) {throw new Message());}}
}

2、我自己写的自定义菜单

package com.wx.service.impl;import com.alibaba.druid.support.logging.Log;
import com.alibaba.druid.support.logging.LogFactory;
import com.winxin.pojo.Token;
import com.winxin.util.CommonUtil;
import com.winxin.util.Constant;
import com.wx.service.MenuService;
import com.wx.util.WeiXinUtil;
import net.sf.json.JSONObject;
import org.springframework.stereotype.Service;@Service
public class MenuServiceImpl implements MenuService {public static Log log = Log(MenuService.class);@Overridepublic JSONObject createMenu(String outputStr) {Object(Constant.POST_CREATE_MENU, outputStr);}
}

3、还有一个工具类

package com.wx.util;import com.alibaba.druid.support.logging.Log;
import com.alibaba.druid.support.logging.LogFactory;
import com.winxin.pojo.*;
import com.winxin.util.CommonUtil;
