目录

准备工作1、定义消息转换工具类2、消息类型常量定义3、接收及回复消息说明3.1 消息接收及回复基础实体类定义3.2 接收及回复文本信息3.4 接收及回复图文信息3.5 接收及回复语音信息3.6 接收及回复视频/小视频信息3.7 接收链接信息3.8 接收位置信息4、完整示例代码

准备工作

1、调用微信公众号接口，需要实现获取AccessToken，参考《获取AccessToken接口调用凭据》

2、在本地进行联调时，为让微信端能够访问到本地服务，需要进行内网穿透，参考《本地服务器内网穿透实现（NATAPP）》

3、配置微信接口配置信息，用于告诉微信接收消息的回调地址

1、定义消息转换工具类

WeixinMessageUtil

@Componentpublic class WeixinMessageUtil {/*** 将二进制数据转换为16进制字符串** @param src* @return*/public static String byte2HexString(byte[] src) {StringBuilder stringBuilder = new StringBuilder();if (src == null || src.length <= 0) {return null;}for (byte b : src) {String hv = Integer.toHexString(b & 0xFF);if (hv.length() < 2) {stringBuilder.append(0);}stringBuilder.append(hv);}return stringBuilder.toString();}/*** 对字符串进行sha1加签** @param context* @return* @throws Exception*/public static String sha1(String context) throws Exception {// 获取sha1算法封装类MessageDigest sha1Digest = MessageDigest.getInstance("SHA-1");// 进行加密byte[] digestResult = sha1Digest.digest(context.getBytes("UTF-8"));// 转换为16进制字符串return WeixinMessageUtil.byte2HexString(digestResult);}/*** 将输入流使用指定编码转化为字符串 获取xml** @param request* @return* @throws Exception*/public static String inputStream2String(HttpServletRequest request) throws Exception {InputStream io = request.getInputStream();// 建立输入流读取类InputStreamReader reader = new InputStreamReader(io, "UTF-8");// 设定每次读取字符个数char[] data = new char[512];int dataSize = 0;// 循环读取StringBuilder stringBuilder = new StringBuilder();while ((dataSize = reader.read(data)) != -1) {stringBuilder.append(data, 0, dataSize);}return stringBuilder.toString();}public static Map<String, String> xmlToMap(HttpServletRequest request) throws IOException, DocumentException {Map<String, String> map = new HashMap<>();SAXReader reader = new SAXReader();InputStream io = request.getInputStream();Document document = (Document) reader.read(io);Element root = document.getRootElement();List<Element> elements = root.elements();for (Element element : elements) {map.put(element.getName(), element.getText());}io.close();return map;}/*** 将对象转化为xml字符串。 rootName 为根节点名称** @param obj* @return* @throws Exception*/public static String obj2Xml(Object obj) {XStream xstream = new XStream();xstream.alias("xml", obj.getClass());return xstream.toXML(obj);}}

2、消息类型常量定义

public class MessageType {/*** 请求消息类型：文本*/public static final String REQ_MESSAGE_TYPE_TEXT = "text";/*** 请求消息类型：图片*/public static final String REQ_MESSAGE_TYPE_IMAGE = "image";/*** 请求消息类型：语音*/public static final String REQ_MESSAGE_TYPE_VOICE = "voice";/*** 请求消息类型：视频*/public static final String REQ_MESSAGE_TYPE_VIDEO = "video";/*** 请求消息类型：链接*/public static final String REQ_MESSAGE_TYPE_LINK = "link";/*** 请求消息类型：地理位置*/public static final String REQ_MESSAGE_TYPE_LOCATION = "location";/*** 请求消息类型：小视频*/public static final String REQ_MESSAGE_TYPE_SHORTVIDEO = "shortvideo";/*** 请求消息类型：事件推送*/public static final String REQ_MESSAGE_TYPE_EVENT = "event";/*** 返回消息类型：文本*/public static final String RESP_MESSAGE_TYPE_TEXT = "text";/*** 消息返回类型：图片*/public static final String RESP_MESSAGE_TYPE_IMAGE = "image";/*** 消息返回类型:语音*/public static final String RESP_MESSAGE_TYPE_VOICE = "voice";/*** 消息返回类型：音乐*/public static final String RESP_MESSAGE_TYPE_MUSIC = "music";/*** 消息返回类型：图文*/public static final String RESP_MESSAGE_TYPE_NEWS = "news";/*** 消息返回类型：视频*/public static final String RESP_MESSAGE_TYPE_VIDEO = "video";/*** 事件类型:订阅*/public static final String EVENT_TYPE_SUBSCRIBE = "subscribe";/*** 事件类型：取消订阅*/public static final String EVENT_TYPE_UNSUBSCRIBE = "unsubscribe";/*** 事件类型：scan(关注用户扫描带参二维码)*/public static final String EVENT_TYPE_SCAN = "SCAN";/*** 事件类型：location(上报地理位置)*/public static final String EVENT_TYPE_LOCATION = "LOCATION";/*** 事件类型：CLICK(点击菜单拉取消息)*/public static final String EVENT_TYPE_CLICK = "CLICK";/*** 事件类型：VIEW(自定义菜单URl视图)*/public static final String EVENT_TYPE_VIEW = "VIEW";}
