基于springboot+mybatis的微信公众号开发第四篇-自定义菜单的查询、创建、删除及菜单事件响应

菜单这部分相对来说是简单的，所以做起来很快。

一、看公众号的文档可知有些接口调用可能要https请求，所以这里我们在util包中创建一个书信任管理器类

package com.util;

import java.security.cert.CertificateException;
import java.security.cert.X509Certificate;

import javax.net.ssl.X509TrustManager;

/**
 * 证书信任管理器（用于https请求）
 *
 */
public class MyX509TrustManager implements X509TrustManager {

    public void checkClientTrusted(X509Certificate[] chain, String authType) throws CertificateException {
    }

    public void checkServerTrusted(X509Certificate[] chain, String authType) throws CertificateException {
    }

    public X509Certificate[] getAcceptedIssuers() {
        return null;
    }
}

**二、我们在同个包下的WeixinUtil类，加入用于通用的https请求方法
这里罗列整个类的代码（加上了获取AccessToken的固定方法）**

package com.util;

import com.model.AccessToken;
import net.sf.json.JSONException;
import net.sf.json.JSONObject;
import java.io.BufferedReader;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.io.OutputStream;
import java.net.ConnectException;
import java.net.URL;

import javax.net.ssl.HttpsURLConnection;
import javax.net.ssl.SSLContext;
import javax.net.ssl.SSLSocketFactory;
import javax.net.ssl.TrustManager;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;


/**
 * Created by Administrator on 2016/11/7.
 */
public class WeixinUtil {
    private static Logger log = LoggerFactory.getLogger(WeixinUtil.class);

    /**
     * 发起https请求并获取结果
     *
     * @param requestUrl 请求地址
     * @param requestMethod 请求方式（GET、POST）
     * @param outputStr 提交的数据
     * @return JSONObject(通过JSONObject.get(key)的方式获取json对象的属性值)
     */
    public static JSONObject httpRequest(String requestUrl, String requestMethod, String outputStr) {
        JSONObject jsonObject = null;
        StringBuffer buffer = new StringBuffer();
        try {
            // 创建SSLContext对象，并使用我们指定的信任管理器初始化
            TrustManager[] tm = { new MyX509TrustManager() };
            SSLContext sslContext = SSLContext.getInstance("SSL", "SunJSSE");
            sslContext.init(null, tm, new java.security.SecureRandom());
            // 从上述SSLContext对象中得到SSLSocketFactory对象
            SSLSocketFactory ssf = sslContext.getSocketFactory();

            URL url = new URL(requestUrl);
            HttpsURLConnection httpUrlConn = (HttpsURLConnection) url.openConnection();
            httpUrlConn.setSSLSocketFactory(ssf);

            httpUrlConn.setDoOutput(true);
            httpUrlConn.setDoInput(true);
            httpUrlConn.setUseCaches(false);
            // 设置请求方式（GET/POST）
            httpUrlConn.setRequestMethod(requestMethod);

            if ("GET".equalsIgnoreCase(requestMethod))
                httpUrlConn.connect();

            // 当有数据需要提交时
            if (null != outputStr) {
                OutputStream outputStream = httpUrlConn.getOutputStream();
                // 注意编码格式，防止中文乱码
                outputStream.write(outputStr.getBytes("UTF-8"));
                outputStream.close();
            }

            // 将返回的输入流转换成字符串
            InputStream inputStream = httpUrlConn.getInputStream();
            InputStreamReader inputStreamReader = new InputStreamReader(inputStream, "utf-8");
            BufferedReader bufferedReader = new BufferedReader(inputStreamReader);

            String str = null;
            while ((str = bufferedReader.readLine()) != null) {
                buffer.append(str);
            }
            bufferedReader.close();
            inputStreamReader.close();
            // 释放资源
            inputStream.close();
            inputStream = null;
            httpUrlConn.disconnect();
            jsonObject = JSONObject.fromObject(buffer.toString());
        } catch (ConnectException ce) {
            log.error("Weixin server connection timed out.");
        } catch (Exception e) {
            log.error("https request error:{}", e);
        }
        return jsonObject;
    }

    // 获取access_token的接口地址（GET） 限200（次/天）
    public final static String access_token_url = "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=APPID&secret=APPSECRET";

    /**
     * 获取access_token
     *
     * @param appid 凭证
     * @param appsecret 密钥
     * @return
     */
    public static AccessToken getAccessToken(String appid, String appsecret) {
        AccessToken accessToken = null;

        String requestUrl = access_token_url.replace("APPID", appid).replace("APPSECRET", appsecret);
        JSONObject jsonObject = httpRequest(requestUrl, "GET", null);
        // 如果请求成功
        if (null != jsonObject) {
            try {
                accessToken = new AccessToken();
                accessToken.setToken(jsonObject.getString("access_token"));
                accessToken.setExpiresIn(jsonObject.getInt("expires_in"));
            } catch (JSONException e) {
                accessToken = null;
                // 获取token失败
                log.error("获取token失败 errcode:{} errmsg:{}", jsonObject.getInt("errcode"), jsonObject.getString("errmsg"));
            }
        }
        return accessToken;
    }

}

三、接下来要写实体类了

1、写个AccessToken的实体类吧，以后要用到。

package com.model;

/**
 * 微信通用接口凭证
 *
 */
public class AccessToken {
    // 获取到的凭证
    private String token;
    // 凭证有效时间，单位：秒
    private int expiresIn;

    public String getToken() {
        return token;
    }

    public void setToken(String token) {
        this.token = token;
    }

    public int getExpiresIn() {
        return expiresIn;
    }

    public void setExpiresIn(int expiresIn) {
        this.expiresIn = expiresIn;
    }
}

2、然后是菜单的实体类。在model包下创建一个menu包，包下创建Menu类（主要是为了好看）

package com.model.menu;

import java.sql.Timestamp;

public class Menu {

    private String id;

    private String accountId;

    private String parentId;

    private String parentName;

    private String name;

    private String type;

    private String key;

    private String url;

    private Integer sort;

    private String createdBy;

    private Timestamp createdTime;

    public String getId() {
        return id;
    }

    public void setId(String id) {
        this.id = id;
    }

    public String getAccountId() {
        return accountId;
    }

    public void setAccountId(String accountId) {
        this.accountId = accountId;
    }

    public String getParentId() {
        return parentId;
    }

    public void setParentId(String parentId) {
        this.parentId = parentId;
    }

    public String getParentName() {
        return parentName;
    }

    public void setParentName(String parentName) {
        this.parentName = parentName;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getType() {
        return type;
    }

    public void setType(String type) {
        this.type = type;
    }

    public String getKey() {
        return key;
    }

    public void setKey(String key) {
        this.key = key;
    }

    public Integer getSort() {
        return sort;
    }

    public void setSort(Integer sort) {
        this.sort = sort;
    }

    public String getCreatedBy() {
        return createdBy;
    }

    public void setCreatedBy(String createdBy) {
        this.createdBy = createdBy;
    }

    public Timestamp getCreatedTime() {
        return createdTime;
    }

    public void setCreatedTime(Timestamp createdTime) {
        this.createdTime = createdTime;
    }

    public String getUrl() {
        return url;
    }

    public void setUrl(String url) {
        this.url = url;
    }
}

四、写菜单的逻辑层

1、在service包创建menu包，并在下面创建MenuService

package com.service.menu;

import net.sf.json.JSONObject;
import java.util.Map;


public interface MenuService {
    public JSONObject getMenu(String accessToken);
    public int createMenu(Map<String, Object> menu, String accessToken);
    public int deleteMenu(String accessToken);




}

然后再创建实现类MenuServiceImpl

package com.service.menu;

import com.model.menu.Menu;
import com.util.WeixinUtil;
import net.sf.json.JSONObject;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;

/**
 * 对订阅号的菜单的操作
 */
@SuppressWarnings("SpringJavaAutowiringInspection")
@Service("menuService")
public class MenuSeviceImpl implements MenuService {


    private static Logger log = LoggerFactory.getLogger(MenuSeviceImpl.class);

    // 菜单创建（POST） 限1000（次/天）
    public static String menu_create_url = "https://api.weixin.qq.com/cgi-bin/menu/create?access_token=ACCESS_TOKEN";

    // 菜单查询（POST） 限10000（次/天）
    public static String menu_get_url = "https://api.weixin.qq.com/cgi-bin/menu/get?access_token=ACCESS_TOKEN";

    // 菜单删除（POST） 限1000（次/天）
    public static String menu_delete_url = "https://api.weixin.qq.com/cgi-bin/menu/delete?access_token=ACCESS_TOKEN";



    /**
     * 查询菜单
     *
     * @param accessToken 有效的access_token
     * @return
     */
    public JSONObject getMenu(String accessToken) {

        // 拼装创建菜单的url
        String url = menu_get_url.replace("ACCESS_TOKEN", accessToken);
        // 调用接口查询菜单
        JSONObject jsonObject = WeixinUtil.httpRequest(url, "GET", null);

        return jsonObject;
    }
    /**
     * 创建菜单(替换旧菜单)
     *
     * @param accessToken 有效的access_token
     * @return 0表示成功，其他值表示失败
     */
    public int createMenu(Map<String, Object> menu,String accessToken) {
        int result = 0;

        // 拼装创建菜单的url
        String url = menu_create_url.replace("ACCESS_TOKEN", accessToken);
        // 将菜单对象转换成json字符串
        String jsonMenu = JSONObject.fromObject(menu).toString();
        // 调用接口创建菜单
        JSONObject jsonObject = WeixinUtil.httpRequest(url, "POST", jsonMenu);

        if (null != jsonObject) {
            if (0 != jsonObject.getInt("errcode")) {
                result = jsonObject.getInt("errcode");
                log.error("创建菜单失败 errcode:{} errmsg:{}", jsonObject.getInt("errcode"), jsonObject.getString("errmsg"));
                log.error("****"+jsonMenu+"****");
            }
        }
        return result;
    }

    /**
     * 删除菜单
     *
     * @param accessToken 有效的access_token
     * @return 0表示成功，其他值表示失败
     */
    public int deleteMenu(String accessToken) {
        int result = 0;

        // 拼装创建菜单的url
        String url = menu_delete_url.replace("ACCESS_TOKEN", accessToken);

        // 调用接口创建菜单
        JSONObject jsonObject = WeixinUtil.httpRequest(url, "POST", null);

        if (null != jsonObject) {
            if (0 != jsonObject.getInt("errcode")) {
                result = jsonObject.getInt("errcode");
                log.error("删除菜单失败 errcode:{} errmsg:{}", jsonObject.getInt("errcode"), jsonObject.getString("errmsg"));
            }
        }
        return result;
    }
}

五、在com包下创建一个thread包，再创建AccessTokenThread类，用来定时获取access_token

1、首先在启动类中加入注解@EnableScheduling

package com;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.scheduling.annotation.EnableScheduling;

@SpringBootApplication
@EnableScheduling // 这里，启用定时任务
public class WeixinMpApplication {

    public static void main(String[] args) {
        SpringApplication.run(WeixinMpApplication.class, args);
    }
}

2、在AccessTokenThread类中加入

package com.thread;

import com.model.accesstoken.AccessToken;
import com.util.WeixinUtil;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Component;

/**
 * 定时获取微信access_token的线程
 *在WechatMpDemoApplication中注解@EnableScheduling，在程序启动时就开启定时任务。
 * 每7200秒执行一次
 */
@Component
public class AccessTokenThread {
    private static Logger log = LoggerFactory.getLogger(AccessTokenThread.class);

    // 第三方用户唯一凭证
    public static String appid = "wx1dd7aa8ed2be67e7";

    // 第三方用户唯一凭证密钥
    public static String appsecret = "ae9d55c58f0d87208f63eb229eb74926";
    // 第三方用户唯一凭证
    public static AccessToken accessToken = null;

    @Scheduled(fixedDelay = 2*3600*1000)
    //7200秒执行一次
    public void gettoken(){
        accessToken= WeixinUtil.getAccessToken(appid,appsecret);
        if(null!=accessToken){
            log.info("获取成功，accessToken:"+accessToken.getToken());
        }else {
            log.error("获取token失败");
        }
    }
}

六、在controller包下创建MenuController类,这里是直接组装固定菜单。

package com.controller;


import com.model.menu.Menu;
import com.service.menu.MenuService;
import com.thread.AccessTokenThread;
import net.sf.json.JSONObject;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;

import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;

/**
 *
 * 对订阅号的菜单的操作
 *
 */
@RestController
@RequestMapping("/menu")

public class MenuController {
    @Autowired
    private MenuService menuService;


    private static Logger log = LoggerFactory.getLogger(MenuController.class);

    //查询全部菜单
    @RequestMapping(value = "/get",method = RequestMethod.GET)
    public String getMenu() {
        // 调用接口获取access_token
        String at = AccessTokenThread.accessToken.getToken();
        JSONObject jsonObject =null;
        if (at != null) {
            // 调用接口查询菜单
            jsonObject = menuService.getMenu(at);
            // 判断菜单创建结果
            return String.valueOf(jsonObject);
        }
        log.info("token为"+at);
        return "无数据";
    }

    //创建菜单
    @RequestMapping(value = "/create",method = RequestMethod.POST)
    public int createMenu() {
        // 调用接口获取access_token
        String at = AccessTokenThread.accessToken.getToken();
        int result=0;
        if (at != null) {

            // 调用接口创建菜单
            result = menuService.createMenu(getFirstMenu(),at);
            // 判断菜单创建结果
            if (0 == result) {
                log.info("菜单创建成功！");
            } else {
                log.info("菜单创建失败，错误码：" + result);
            }
        }
        return result ;
    }

    //删除菜单
    @RequestMapping(value = "/delete",method = RequestMethod.POST)
    public int deleteMenu() {
        // 调用接口获取access_token
        String at = AccessTokenThread.accessToken.getToken();
        int result=0;
        if (at != null) {
            // 删除菜单
            result = menuService.deleteMenu(at);
            // 判断菜单删除结果
            if (0 == result) {
                log.info("菜单删除成功！");
            } else {
                log.info("菜单删除失败，错误码：" + result);
            }
        }
        return  result;
    }




        /**
         * 组装菜单数据
         */
    public static Map<String, Object> getFirstMenu(){
        //第一栏菜单
        Menu menu1=new Menu();
        menu1.setId("1");
        menu1.setName("第一栏");
        menu1.setType("click");
        menu1.setKey("1");

        Menu menu11=new Menu();
        menu11.setId("11");
        menu11.setName("第一栏的第一个v3");
        menu11.setType("click");
        menu11.setKey("11");

        Menu menu12=new Menu();
        menu12.setId("12");
        menu12.setName("第一栏的第二个");
        menu12.setType("click");
        menu12.setKey("12");

        //第二栏
        Menu menu2=new Menu();
        menu2.setId("2");
        menu2.setName("第二栏");
        menu2.setType("click");
        menu2.setKey("2");

        Menu menu21=new Menu();
        menu21.setId("21");
        menu21.setName("第二栏的第一个");
        menu21.setType("click");
        menu21.setKey("21");



        Menu menu3=new Menu();
        menu3.setId("3");
        menu3.setName("第三栏");
        menu3.setType("view");
        menu3.setUrl("http://www.baidu.com");

        //最外一层大括号
        Map<String, Object> wechatMenuMap = new HashMap<String, Object>();

        //包装button的List
        List<Map<String, Object>> wechatMenuMapList = new ArrayList<Map<String, Object>>();

        //包装第一栏
        Map<String, Object> menuMap1 = new HashMap<String, Object>();
        Map<String, Object> menuMap11 = new HashMap<String, Object>();
        Map<String, Object> menuMap12 = new HashMap<String, Object>();
        List<Map<String, Object>> subMenuMapList1 = new ArrayList<Map<String, Object>>();


        //第一栏第一个
        menuMap11.put("name",menu11.getName());
        menuMap11.put("type",menu11.getType());
        menuMap11.put("key",menu11.getKey());
        subMenuMapList1.add(menuMap11);

        //第二栏第二个
        menuMap12.put("name",menu12.getName());
        menuMap12.put("type",menu12.getType());
        menuMap12.put("key",menu12.getKey());
        subMenuMapList1.add(menuMap12);

        menuMap1.put("name",menu1.getName());
        menuMap1.put("sub_button",subMenuMapList1);

        //包装第二栏
        Map<String, Object> menuMap2 = new HashMap<String, Object>();
        Map<String, Object> menuMap21 = new HashMap<String, Object>();
        List<Map<String, Object>> subMenuMapList2 = new ArrayList<Map<String, Object>>();

        //第二栏第一个
        menuMap21.put("name",menu21.getName());
        menuMap21.put("type",menu21.getType());
        menuMap21.put("key",menu21.getKey());
        subMenuMapList2.add(menuMap21);

        menuMap2.put("name",menu2.getName());
        menuMap2.put("sub_button",subMenuMapList2);

        //包装第三栏
        Map<String, Object> menuMap3 = new HashMap<String, Object>();
        List<Map<String, Object>> subMenuMapList3 = new ArrayList<Map<String, Object>>();

        menuMap3.put("name",menu3.getName());
        menuMap3.put("type",menu3.getType());
        menuMap3.put("url",menu3.getUrl());
        menuMap3.put("sub_button",subMenuMapList3);


        wechatMenuMapList.add(menuMap1);
        wechatMenuMapList.add(menuMap2);
        wechatMenuMapList.add(menuMap3);
        wechatMenuMap.put("button",wechatMenuMapList);
        return  wechatMenuMap;
    }
}

六、点击菜单响应事件

因为点击菜单属于事件推送，所以要在CoreServiceImpl类中相应位置新加入对事件推送的处理方法：

1、在接收文本消息前新增菜单id属性

            //点击菜单id
            String EventKey =requestMap.get("EventKey");
            // 接收文本消息内容
            String content = requestMap.get("Content");

2、在音频消息后面加入事件推送的处理

            // 事件推送
            else if (msgType.equals(MessageUtil.REQ_MESSAGE_TYPE_EVENT)) {
                // 事件类型
                String eventType =requestMap.get("Event");
                // 自定义菜单点击事件
                 if (eventType.equals(MessageUtil.EVENT_TYPE_CLICK)) {
                    switch (EventKey){
                        case "11":{
                            respContent = "这是第一栏第一个";
                            break;
                        }
                        case "12":{
                            respContent = "这是第一栏第一个";
                            break;
                        }
                        case "21":{
                            respContent = "这是第二栏第一个";
                            break;
                        }

                        default:{
                            log.error("开发者反馈：EventKey值没找到，它是:"+EventKey);
                            respContent= "很抱歉，此按键功能正在升级无法使用";
                        }
                    }
                    textMessage.setContent(respContent);
                    // 将文本消息对象转换成xml字符串
                    respMessage = MessageUtil.textMessageToXml(textMessage);
                }
                else if(eventType.equals(MessageUtil.EVENT_TYPE_VIEW)){
                    // 对于点击菜单转网页暂时不做推送
                }

            }

3、后面我加入了对订阅消息的推送处理。

// 订阅
                else if (eventType.equals(MessageUtil.EVENT_TYPE_SUBSCRIBE)) {
                    //测试单图文回复
                    Article article = new Article();
                    article.setTitle("谢谢您的关注！");
                    // 图文消息中可以使用QQ表情、符号表情
                    article.setDescription("点击图文可以跳转到百度首页");
                    // 将图片置为空
                    article.setPicUrl("http://www.sinaimg.cn/dy/slidenews/31_img/2016_38/28380_733695_698372.jpg");
                    article.setUrl("http://www.baidu.com");
                    articleList.add(article);
                    newsMessage.setArticleCount(articleList.size());
                    newsMessage.setArticles(articleList);
                    respMessage = MessageUtil.newsMessageToXml(newsMessage);
                }
                else if(eventType.equals(MessageUtil.EVENT_TYPE_SCAN)){
                    //测试单图文回复
                    Article article = new Article();
                    article.setTitle("这是已关注用户扫描二维码弹到的界面");
                    // 图文消息中可以使用QQ表情、符号表情
                    article.setDescription("点击图文可以跳转到百度首页");
                    // 将图片置为空
                    article.setPicUrl("http://www.sinaimg.cn/dy/slidenews/31_img/2016_38/28380_733695_698372.jpg");
                    article.setUrl("http://www.baidu.com");
                    articleList.add(article);
                    newsMessage.setArticleCount(articleList.size());
                    newsMessage.setArticles(articleList);
                    respMessage = MessageUtil.newsMessageToXml(newsMessage);
                }
                // 取消订阅
                else if (eventType.equals(MessageUtil.EVENT_TYPE_UNSUBSCRIBE)) {
                    // TODO 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
                }
