如果微信服务号或者订阅号一旦接入了开发者模式，微信的后台自动回复后台的配置就会消失，菜单配置也会消失，这时候就需要开发人员写代码来维护！第一步：填写服务器配置
1.可以参照微信官方文档点击打开链接 基本上不会错唯一注意的是url 一定要是外网的地址而且端口是80或者443
![]()
第二步：验证消息的确来自微信服务器
@RequestMapping(value="/service",method={RequestMethod.GET})
@ResponseBody
public void index(HttpServletRequest request,HttpServletResponse response) throws Exception{
request.setCharacterEncoding("UTF-8");
response.setCharacterEncoding("UTF-8");
String signature = request.getParameter("signature");
String timestamp = request.getParameter("timestamp");
String nonce = request.getParameter("nonce");
String echostr = request.getParameter("echostr");
String result = "";
if(StringUtil.isNotEmpty(echostr)){
String[] arr = new String[] {TOKEN, timestamp, nonce};
StringBuilder content = new StringBuilder();
for (int i = 0; i < arr.length; i++) {
content.append(arr[i]);
}
Arrays.sort(arr);
Boolean checkFlag = content ==null ? false : signature.equals(EncryptUtils.SHA1(content.toString()));
result = echostr;
}else{
Map<String,String> map = WeixinFormatXmlProcess.parseXml(request);
String content = map.get("Content");
String ToUserName = map.get("ToUserName");
String FromUserName = map.get("FromUserName");
String replayMessage = WeixinFormatXmlProcess.formatXmlAnswer(ToUserName, FromUserName,content);
result = replayMessage;
}
PrintWriter pw = response.getWriter();
response.setContentType("text/plain");
pw.write(result);
pw.flush();
pw.close();
}第三步：依据接口文档实现业务逻辑

if(StringUtil.isNotEmpty(replayMessage)){

}
}

}
}
}
}
return replayMessage ;
}

}这个方法是第一步里面配置的url 这时候只要用户和公众号交互就会进入这个方法这时候用户就可以在这个方法里面写用户关注、关键字回复的消息。这个方法也可以拿到用户的openid 拿到用户open_id特别需要注意这是微信的服务端的方法。所以拿到open_id不能存在session里面需要存到数据库里面。获取open_id 有两种方式第一种是在这个方法里面，第二种是通过网页授权获取后面会讲到。怎么通过网页授权拿到open_id。这里基本上可以回复图文消息、文字消息、图片消息。
文字消息
图文消息（这里需要注意最多只能八条图文一次性）
至此基本上完成了微信的消息服务。基本上这些回复做成后台可配置的附上一些后台的截图
