OTO Food App Real-time push order to store program detailed implementation (II)

The article "Oto Catering app real-time order tracking System Architecture Design" article.

After the user generates a takeaway order, you can send a text message to inform the store to have an order, but the shortcomings of the SMS method is very obvious, if you want to let users and websites know that the store to accept orders and other operations need site human intervention, which is not available before the smartphone, those takeout sites such operations are understandable, But the smartphone has been out for so many years, and now some of the takeout sites are still operating so I am difficult to understand. The last time I used "hungry" the next takeaway orders, after the order, hungry customer service immediately call to confirm the order, I do not know whether the customer service after confirmation call to the store to notify the order. I am also very dissatisfied with this experience, not satisfied with the process, not the service.

It's a little far away.

5.2.1 User app submits order business logic layer:

				Order.sethowmuch (total);
				Order.setmenu (menulist);
				Order.setordertype (0x001);  The representative is the takeaway order
				Order.setpaytype (0x002);    Alipay Online Payment	
				order.setuser_id (1/*integer.parseint (Mapplication.getmuser () getId ()) */);
				Send the order out
				orderserver orderserver = new Orderserver ();
				Orderserver.dealorder (order,new Asynchttpresponsehandler () {
					 @Override public
					 void Onsuccess (String Response) {
					    	if (!response.equals ("0"))
					    	{
					    	    log.i ("takeawaycommitactivity", "Submit order succeeded" + response);
					    	    StartActivity (New Intent (Takeawaycommitactivity.this,paysuccessactivity.class));
					    	    Finish ();
					    	}
					 }
					@Override public
					void OnFailure (throwable error, String content) {

					}
				});

5.2.2 Web server receive orders

The Web server receives the order, generates the order sequence number, writes to the database, and forwards the necessary information for the order to the store app.

The Web server uses the Java EE SSH framework. Originally e-Commerce Web site with PHP should be better.

Package cmyy.web.action.user;

Import java.io.IOException;
Import Org.apache.struts2.ServletActionContext;
Import Org.ddpush.im.util.StringUtil;
Import Org.ddpush.im.v1.client.appserver.Pusher;
Import Com.google.gson.Gson;

Import Com.google.gson.reflect.TypeToken;
Import Cmyy.domain.bussiness.BussinessOrder;
Import Cmyy.domain.bussiness.Order;
Import Cmyy.utils.MD5Utils;
Import cmyy.web.action.base.BaseAction;
Import Javax.servlet.http.HttpServletRequest;
	Order submission public class Orderaction extends baseaction{private httpservletrequest req;
        public void Ordersubmit () {req = Servletactioncontext.getrequest ();
        Gson Gson = new Gson ();
        Order order = Gson.fromjson (Req.getparameter ("req"), new Typetoken<order> () {}.gettype ());
		Forward to the tracking server to push to the corresponding store byte[] bussinessid = null;
		try {bussinessid = Stringutil.md5byte (string.valueof (Order.getbussiness (). GetId ())); } catch (Exception E1) {//TODO auto-generated catch block E1.printstacktrace ();
		}//Store id pusher pusher = null;
        Bussinessorder Bussinessorder = new Bussinessorder ();
 
		Bussinessorder.setorder_uuid ("Dajldahgiahlajl");
			The try {//push server IP address can be placed in the configuration file, where the value is temporarily written pusher = new Pusher ("127.0.0.1", 9999, 1000*5); 
	        Boolean result = Pusher.push0x20message (Bussinessid,gson.tojson (Bussinessorder). GetBytes ());  
	        if (result) {System.out.println ("Common Information sent successfully"); }else{System.out.println ("Send failed.  
	        Format is incorrect ");
		}} catch (Exception e) {//TODO auto-generated catch block E.printstacktrace ();
		}//Generate order number information try {outprint (Req.getparameter ("req"));
		} catch (IOException e) {//TODO auto-generated catch block E.printstacktrace ();
 }
