1、訊息轉發地址填寫，需要注意的是token和encodingaeskey要和專案中配置一致

2、URL要實現兩個路由相同的方法但是一個需要時GET另一個是POST，如下，其中TOKEN引數需要與微信後臺配置一致；

  @ResponseBody
  @RequestMapping(method=RequestMethod.GET,produces= "text/plain;charset=utf-8")
  public void authGet(@RequestParam(name = "signature", required = false) String signature,
      @RequestParam(name = "timestamp", required = false) String timestamp,
      @RequestParam(name = "nonce", required = false) String nonce,
      @RequestParam(name = "echostr", required = false) String echostr,HttpServletResponse response) throws Exception {
    this.logger.info("\n接收到來自微信伺服器的認證訊息：[{}, {}, {}, {}]", signature, timestamp, nonce, echostr);

    if (StringUtils.isAnyBlank(signature, timestamp, nonce, echostr)) {
      throw new IllegalArgumentException("請求引數非法，請核實!");
    }
    
    String[] str = { TOKEN, timestamp, nonce };
    Arrays.sort(str); // 字典序排序
    String bigStr = str[0] + str[1] + str[2];
    // SHA1加密
    SHA1 sha1= new SHA1();
    String digest =sha1.gen(str);

    // 確認請求來至微信
    if (digest.equals(signature)) {
        response.getWriter().print(echostr);
    }
   }
 

  /**
   * POST請求：
   * 接收客服訊息； 
   * 此處的value值也就是往微信公眾平臺要配置的請求的地址
   */
  @ResponseBody
  @RequestMapping(method=RequestMethod.POST)
  public JSONObject doMessagePost(HttpServletRequest request,HttpServletResponse response) {
      try {
          ServletInputStream stream = request.getInputStream();
           BufferedReader reader = new BufferedReader(new InputStreamReader(stream));
           StringBuffer buffer = new StringBuffer();
           String line = new String("");  
           while((line = reader.readLine()) != null){
               buffer.append(line);
           }
			JSONObject jsonObject = JSONObject.fromObject(buffer.toString());

			String to=jsonObject.getString("ToUserName");
			String from=jsonObject.getString("FromUserName");
			String time=jsonObject.getString("CreateTime");
			String sessionFrom=jsonObject.getString("SessionFrom");
			String msgType=jsonObject.getString("MsgType");
			
			PrintWriter out=response.getWriter(); 
			
			String msg="<xml>\r\n" +

					"     <CreateTime>"+time+"</CreateTime>\r\n" + 
					"     <MsgType><![CDATA[transfer_customer_service]]></MsgType>\r\n" + 
					" </xml>";

			out.print(msg);
			
			if("event".equals(msgType)&&"follow".equals(sessionFrom)) {
				pushService.setSendCustomerMsgLink(from);
			}
      } catch (Exception e) {
          e.printStackTrace();
      }
      return null;
  }
 

<MsgType><![CDATA[transfer_customer_service]]></MsgType>
