微信第三方平台消息后台处理
1 一、微信消息请求路由
2 //注入，处理微信推送消息的处理器接口
3 @Autowired
4 @Qualifier("textHandler")
5 private WxMpMessageHandler textHandler;
6 @Autowired
7 @Qualifier("viewHandler")
8 private WxMpMessageHandler viewHandler;
9 @Autowired
10 @Qualifier("clickHandler")
11 private WxMpMessageHandler clickHandler;
12 @Autowired
13 @Qualifier("subscribeHandler")
14 private WxMpMessageHandler subscribeHandler;
15 @Autowired
16 @Qualifier("unsubscribeHandler")
17 private WxMpMessageHandler unsubscribeHandler;
18
19 /**
20 * 初始化路由过滤规则
21 */
22 @PostConstruct
23 public void init() {
24 wxMpService = new WxMpServiceImpl();
25 wxMpMessageRouter = new WxMpMessageRouter(wxMpService);
26 wxMpMessageRouter
27 .rule()
28 .async(false)
29 .msgType(WxConsts.XML_MSG_EVENT).event(WxConsts.EVT_SUBSCRIBE) // 微信推送过来的消息的类型，和发送给微信xml格式消息的消息类型
30 .handler(subscribeHandler)
31 .end()
32 .rule()
33 .async(false)
34 .msgType(WxConsts.XML_MSG_EVENT).event(WxConsts.EVT_UNSUBSCRIBE)
35 .handler(unsubscribeHandler)
36 .end()
37 .rule()
38 .async(false)
39 .msgType(WxConsts.XML_MSG_EVENT).event(WxConsts.EVT_VIEW)
40 .handler(viewHandler)
41 .end()
42 .rule()
43 .async(false)
44 .msgType(WxConsts.XML_MSG_EVENT).event(WxConsts.EVT_CLICK)
45 .handler(clickHandler)
46 .end()
47 .rule()
48 .async(false)
49 .msgType(WxConsts.XML_MSG_TEXT)
50 .handler(textHandler)
51 .end();
52 }
53 /**
54 * 消息处理
55 */
56 public String getHandlePost(String xmlMsg,String appid) {
57 logger.info("消息处理：{}{}",xmlMsg,appid);
58 WxMpXmlMessage message = XStreamTransformer.fromXml(WxMpXmlMessage.class, xmlMsg);
59 WxMpXmlOutMessage outMessage = wxMpMessageRouter.route(message,appid);
60 // TODO
61 //日志记录
62 // WXJTransLog WXJTransLog = new WXJTransLog();
63 // WXJTransLog.setLogid(IDUtils.getMsgId());
64 // WXJTransLog.setPlatformid(message.getToUserName());
65 // WXJTransLog.setEvent(message.getEvent());
66 // WXJTransLog.setEventkey(message.getEventKey());
67 // WXJTransLog.setFromusername(message.getFromUserName());
68 // WXJTransLog.setMsgtype(message.getMsgType());
69 // WXJTransLog.setCreagetime(DateUtil.getDate());
70 // WXJTransLog.setTextcontext(message.getContent());
71 // if(message.getMsgType().equals(WxConsts.XML_MSG_EVENT)&&message.getEvent().equals(WxConsts.EVT_TEMPLATESENDJOBFINISH)){
72 //
73 // }else{
74 // iWXJTransLogMapper.insertTransLog(WXJTransLog);
75 // }
76 return outMessage.toXml();
77 }
二、处理微信推送消息的处理器接口
1 /**
2 * 处理微信推送消息的处理器接口
3 *
4 * @author Daniel Qian
5 */
6 public interface WxMpMessageHandler {
7
8 /**
9 * @param wxMessage
10 * @param context 上下文，如果handler或interceptor之间有信息要传递，可以用这个
11 * @param wxMpService
12 * @param sessionManager
13 * @return xml格式的消息，如果在异步规则里处理的话，可以返回null
14 */
15 public WxMpXmlOutMessage handle(WxMpXmlMessage wxMessage,
16 Map<String, Object> context,
17 WxMpService wxMpService,
18 WxSessionManager sessionManager,String appid) throws WxErrorException;
19
20 }
三、处理微信消息
1 /**
2 * 处理微信消息
3 * @param wxMessage
4 */
5 @SuppressWarnings("rawtypes")
6 public WxMpXmlOutMessage route(final WxMpXmlMessage wxMessage,final String appid) {
7 if (isDuplicateMessage(wxMessage)) {
8 // 如果是重复消息，那么就不做处理
9 // return null;
10 return WxMpXmlOutMessage.TEXT().build();
11 }
12
13 final List<WxMpMessageRouterRule> matchRules = new ArrayList<WxMpMessageRouterRule>();
14 // 收集匹配的规则
15 for (final WxMpMessageRouterRule rule : rules) {
16 if (rule.test(wxMessage)) {
17 matchRules.add(rule);
18 if(!rule.isReEnter()) {
19 break;
20 }
21 }
22 }
23
24 if (matchRules.size() == 0) {
25 WxMpXmlOutMessage res = null;
26 return res;
27 }
28
29 WxMpXmlOutMessage res = null;
30 final List<Future> futures = new ArrayList<Future>();
31 for (final WxMpMessageRouterRule rule : matchRules) {
32 // 返回最后一个非异步的rule的执行结果
33 if(rule.isAsync()) {
34 futures.add(
35 executorService.submit(new Runnable() {
36 public void run() {
37 rule.service(wxMessage, wxMpService, sessionManager, exceptionHandler,appid);
38 }
39 })
40 );
41 } else {
42 res = rule.service(wxMessage, wxMpService, sessionManager, exceptionHandler,appid);
43 }
44 }
45 return res;
46 }
四、处理微信推送过来的消息rule.service
1 /**
2 * 处理微信推送过来的消息
3 *
4 * @param wxMessage
5 * @return true 代表继续执行别的router，false 代表停止执行别的router
6 */
7 protected WxMpXmlOutMessage service(WxMpXmlMessage wxMessage,
8 WxMpService wxMpService,
9 WxSessionManager sessionManager,
10 WxErrorExceptionHandler exceptionHandler,String appid) {
11
12 try {
13
14 Map<String, Object> context = new HashMap<String, Object>();
15 // 如果拦截器不通过
16 for (WxMpMessageInterceptor interceptor : this.interceptors) {
17 if (!interceptor.intercept(wxMessage, context, wxMpService, sessionManager)) {
18 return null;
19 }
20 }
21
22 // 交给handler处理
23 WxMpXmlOutMessage res = null;
24 for (WxMpMessageHandler handler : this.handlers) {
25 // 返回最后handler的结果
26 res = handler.handle(wxMessage, context, wxMpService, sessionManager,appid);
27 }
28 return res;
29 } catch (WxErrorException e) {
30 exceptionHandler.handle(e);
31 }
32 return null;
33
34 }
五、此时再将之前的handler实现，处理，即可完成微信消息处理
1 /**
2 * 关注公众号事件处理
3 * @author gll
4 * @version 1.0
5 */
6 @Service("subscribeHandler")
7 public class SubscribeHandler extends BaseHandler implements WxMpMessageHandler{
8
9 private static final Logger logger = LogManager.getLogger(SubscribeHandler.class);
10
11 @Autowired
12 private WxdResMessageMapper resMessageMapper;
13 @Autowired
14 private WxdMessageMapper messageMapper;
15 @Autowired
16 private WxbUserMapper userMapper;
17 @Autowired
18 private WxAuthService wxAuthService; //获取accesstoken接口
