springmvc 整合微信

 方式一： ① 配置验证 @RequestMapping(value = "/into", method = RequestMethod.GET, produces = "application/json;charset=UTF-8") public void validate(WeChat wc, PrintWriter out) { String signature = wc.getSignature(); // 微信加密签名 String timestamp = wc.getTimestamp(); // 时间戳 String nonce = wc.getNonce();// 随机数 String echostr = wc.getEchostr();// 随机字符串 System.out.println("加密的签名字符串:" + signature); System.out.println("时间戳:" + timestamp); System.out.println("随机数:" + nonce); System.out.println("随机字符串:" + echostr); // 验证请求确认成功原样返回echostr参数内容，则接入生效，成为开发者成功，否则接入失败 if (ValidationUtil.checkSignauer(signature, timestamp, nonce)) { // 随机字符串 System.out.println("我进来了"); out.print(echostr); } else { System.out.println("不是微信服务器发来的请求,请小心!"); } out.flush(); out.close(); }② 数据处理 @RequestMapping(value = "/into", method = RequestMethod.POST, produces = "application/xml;charset=UTF-8") public void dispose(HttpServletRequest req, HttpServletResponse resp) throws IOException { // 调用核心业务类接收消息、处理消息 // 从请求中读取整个post数据 // 将请求、响应的编码均设置为UTF-8（防止中文乱码） req.setCharacterEncoding("UTF-8"); resp.setCharacterEncoding("UTF-8"); PrintWriter out = resp.getWriter(); InputStream inputStream = req.getInputStream(); String datapacket = IOUtils.toString(inputStream, "UTF-8"); String respMessage = CoreService.processRequest(datapacket); log.info(respMessage); // 响应消息 out.print(respMessage); out.close(); }方式二：@RequestMapping(value = "/into", method = RequestMethod.GET, produces = "text/html;charset=UTF-8") @ResponseBody public String validate(WeChat wc) { String signature = wc.getSignature(); // 微信加密签名 String timestamp = wc.getTimestamp(); // 时间戳 String nonce = wc.getNonce();// 随机数 String echostr = wc.getEchostr();// 随机字符串 System.out.println("加密的签名字符串:" + signature); System.out.println("时间戳:" + timestamp); System.out.println("随机数:" + nonce); System.out.println("随机字符串:" + echostr); // 验证请求确认成功原样返回echostr参数内容，则接入生效，成为开发者成功，否则接入失败 if (ValidationUtil.checkSignauer(signature, timestamp, nonce)) { // 随机字符串 System.out.println("我进来了"); return echostr; } else { System.out.println("不是微信服务器发来的请求,请小心!"); return "error"; } } @RequestMapping(value = "/into", method = RequestMethod.POST, produces = "application/xml;charset=UTF-8") public void dispose(HttpServletRequest req, WeChat wc, HttpServletResponse resp) throws IOException { String signature = wc.getSignature(); // 微信加密签名 String timestamp = wc.getTimestamp(); // 时间戳 String nonce = wc.getNonce();// 随机数 String echostr = wc.getEchostr();// 随机字符串 System.out.println("加密的签名字符串:" + signature); System.out.println("时间戳:" + timestamp); System.out.println("随机数:" + nonce); System.out.println("随机字符串:" + echostr); // 验证请求确认成功原样返回echostr参数内容，则接入生效，成为开发者成功，否则接入失败 resp.setCharacterEncoding("UTF-8"); PrintWriter out = resp.getWriter(); if (ValidationUtil.checkSignauer(signature, timestamp, nonce)) { // 调用核心业务类接收消息、处理消息 // 从请求中读取整个post数据 InputStream inputStream = req.getInputStream(); String datapacket = IOUtils.toString(inputStream, "UTF-8"); String respMessage = CoreService.processRequest(datapacket); log.info(respMessage); // 响应消息 out.print(respMessage); } out.flush(); out.close(); }方式三：（推荐使用）@RequestMapping(value = "/into", method = RequestMethod.GET, produces = "text/html;charset=UTF-8") @ResponseBody public String validate(WeChat wc) { String signature = wc.getSignature(); // 微信加密签名 String timestamp = wc.getTimestamp(); // 时间戳 String nonce = wc.getNonce();// 随机数 String echostr = wc.getEchostr();// 随机字符串 if (ValidationUtil.checkSignauer(signature, timestamp, nonce)) { // 随机字符串 log.info("我进来了"); return echostr; } else { log.error("不是微信服务器发来的请求,请小心!"); return "error"; } } @RequestMapping(value = "/into", method = RequestMethod.POST, produces = "application/xml;charset=UTF-8") @ResponseBody public String dispose(HttpServletRequest req, WeChat wc) throws IOException { String signature = wc.getSignature(); // 微信加密签名 String timestamp = wc.getTimestamp(); // 时间戳 String nonce = wc.getNonce();// 随机数 if (ValidationUtil.checkSignauer(signature, timestamp, nonce)) { // 调用核心业务类接收消息、处理消息 // 从请求中读取整个post数据 InputStream inputStream = req.getInputStream(); String datapacket = IOUtils.toString(inputStream, "UTF-8"); String respMessage = CoreService.processRequest(datapacket); log.info(respMessage); // 响应消息 return respMessage; }else{ log.error("数据处理失败!"); return "error"; } }
