因为认证问题，所以就先用测试账号，点击开发者工具，进入公众平台测试帐号
域名验证：
1.服务器验证，修改接口配置信息：
注意，接口配置信息中，url为你服务器下验证token合法所在的地址的绝对路径，此处为hello/start在服务器下的绝对路径，token为一个约定的钥匙，服务器验证时，微信会用token加密一段字符串，它会把加密字符串用到的其它参数发送到服务器，用服务器定义的token进行加密并拿到结果，随后它会对比两次结果，如果相同则通过验证，所以微信后台的token和服务器上token必须一致，用相同加密方法加密后才能得到相同结果。
验证方法如下：方法为GET
@RequestMapping(value="Start",method=RequestMethod.GET)public void start(HttpServletRequest request, HttpServletResponse response) throws IOException {System.out.println("开始签名校验");//得到服务器传过来的4个参数String signature = request.getParameter("signature");String timestamp = request.getParameter("timestamp");String nonce = request.getParameter("nonce");String echostr = request.getParameter("echostr");ArrayList<String> array = new ArrayList<String>();array.add(signature);array.add(timestamp);array.add(nonce);// 1.将token、timestamp、nonce三个参数进行字典序排序String sortString = sort(token, timestamp, nonce);// 2. 将三个参数字符串拼接成一个字符串进行sha1加密String mytoken = Decript.SHA1(sortString);// 3.将sha1加密后的字符串可与signature对比，标识该请求来源于微信if (mytoken != null && mytoken != "" && mytoken.equals(signature)) {System.out.println("签名校验通过。");response.getWriter().println(echostr); //如果检验成功输出echostr，微信服务器接收到此输出，才会确认检验完成。} else {System.out.println("签名校验失败。");}}
sort方法：
/*** 排序方法* @param token* @param timestamp* @param nonce* @return*/public static String sort(String token, String timestamp, String nonce) {String[] strArray = { token, timestamp, nonce };Arrays.sort(strArray);StringBuilder sbuilder = new StringBuilder();for (String str : strArray) {sbuilder.append(str);}return sbuilder.toString();}
SHA1加密
/*** * @param decript待加密字段* @return*/public static String SHA1(String decript) {try {MessageDigest digest = MessageDigest.getInstance("SHA-1");digest.update(decript.getBytes());byte messageDigest[] = digest.digest();// Create Hex StringStringBuffer hexString = new StringBuffer();// 字节数组转换为 十六进制 数for (int i = 0; i < messageDigest.length; i++) {String shaHex = Integer.toHexString(messageDigest[i] & 0xFF);if (shaHex.length() < 2) {hexString.append(0);}hexString.append(shaHex);}return hexString.toString();} catch (NoSuchAlgorithmException e) {e.printStackTrace();}return "";}
与微信服务器上利用token生成的字符串相同后，则通过验证。
自定义菜单：
利用在线接口调试工具可以直接生成：
首先用公众号账号密码拿到一个基础token，拿到基础接口的一个调用凭证，用于创建菜单，然后自定义菜单
body示例如下：
{"button":[{ "type":"view","name":"一键申请","url":"http://Scanhandle?Page=1"},{"type":"view","name":"进度查询","url":"http://Scanhandle?Page=2"},{"type":"view","name":"个人中心","url":"http://Scanhandle?Page=3"}]}
还可以生成子菜单，自行查阅官方文档。
消息推送：
在微信用户和公众号产生交互的过程中，用户的某些操作会使得微信服务器通过事件推送的形式通知到开发者在开发者中心处设置的服务器地址，此处为验证签名的地址，hello/start在服务器下的绝对路径,方法为POST:，因为消息要符合微信推送XML数据包结构比如：
<xml><ToUserName><![CDATA[toUser]]></ToUserName><FromUserName><![CDATA[fromUser]]></FromUserName><CreateTime>1348831860</CreateTime><MsgType><![CDATA[text]]></MsgType><Content><![CDATA[this is a test]]></Content><MsgId>1234567890123456</MsgId></xml>
所以消息发送要经过一定的格式处理，首先按着格式规范解析订阅用户发送的信息，然后进行相应的回复。
@RequestMapping(value="Start",method=RequestMethod.POST)public void messageRecieve(HttpServletRequest request, HttpServletResponse response) throws IOException {//消息的接受、处理、响应request.setCharacterEncoding("utf-8");response.setCharacterEncoding("utf-8");String respMessage = null;//调用核心业务类型接受消息、处理消息，消息需要进行相应的格式封装respMessage = EastnetService.processRequest(request, response);//响应消息PrintWriter out = response.getWriter();out.print(respMessage);out.close();}

至此基本消息交互和自定义菜单完成，随后为网页授权，订阅用户点击菜单后如果要携带信息进入第三方网站，开发者必须经过用户同意拿到授权token才能进行，用户同意后，开发者就可以拿到用户独一无二的openid，利用网页授权的token和用户id，则可以获取到用户的详细信息。
首先是设置授权回调页面域名，允许网页授权获取用户基本信息。
注意，此处为服务器域名，如果你代码放到baidu服务器下则此处为,不要添加其他内容，否则会出错。
之前自定义菜单点击后就会跳转到scandle这个controller，controller代码如下：

网页只需要进行相应的接收即可得到用户信息并返回相关页面。微信对接基本功能全部实现。
