Spring uses paid treasure sweep code to pay _java

The previous paragraph has been studying Alipay's sweep code to pay, I have to say, Alipay's documentation is really a rotten (at least at the beginning of the first time is MENGBI). The example above in the document is quite different from the example in the demo. Often the document above the example is very simple, and the demo code is very complex, so at the beginning did not know which code to use, and then took a closer look at the demo of those packets inside the code, found also called the document example of those interfaces, this just understand that they are a thing, Only demo to the interface of the document to do some packaging.

First to apply for an enterprise's Alipay account, this account has a PID, you need to add the application to this account, each application has a appid, and a public key and private key. Public and private keys can be generated from the tools provided by Alipay, and Java developers need to use the private key in PKCS6 format. If the application needs to use the Sweep code function, you need to add in the application in person to pay the option, this need to sign. Signed a face-to-face pay function, can not be used directly, because the application needs to be on-line to use, so the development can use the sandbox version of the application, Alipay provided with a sandbox version of the gateway, Alipay Public key, PID and AppID, in the configuration needs to be modified.

Code can directly use the code inside the demo, first in the project to import Alipay provided by the API (note is not the demo code), and then import the demo code, as shown in the figure:

This com.alipay.demo.trade.Main file can be run directly, but you need to configure a resource file:

The

is then run to run the Main.java file. As for our actual application of the sweep code payment code can be directly copy Main.java file in the Test_trade_precreate () function, in the controller to establish a function:

@RequestMapping (value = "/pay/alipay", method = requestmethod.post) public map<string, string> Alipay (@RequestPar

    Am String amount, @RequestParam int userid) {map<string, string> Map = new hashmap<string, string> ();  (required) Merchant website Order system in the unique order number, 64 characters, can only contain letters, numbers, underscores,//need to ensure that the merchant system can not repeat, the proposed database sequence generation, String Outtradeno = "xxxxx" +

    ;

    Extendparams.setsysserviceproviderid ("2088100200300400500");

Payment timeout, defined as 120-minute String timeoutexpress = TIMEOUT;
Product detail list, need to fill in the purchase details,//list<goodsdetail> goodsdetaillist = new arraylist<goodsdetail> (); Create a commodity information, parameter meaning is the commodity ID (use GB), name, Unit price (unit is divided), quantity, if need to add commodity category, see Goodsdetail//Goodsdetail GOODS1 = Goodsdetail.newinst

    Goodsdetaillist.add (GOODS2); Create a sweep code payment request BuiLder, set request parameters Alipaytradeprecreaterequestbuilder Builder = new Alipaytradeprecreaterequestbuilder ().

    Setgoodsdetaillist (goodsdetaillist);
    Alipayf2fprecreateresult result = Tradeservice.tradeprecreate (builder);
        Switch (Result.gettradestatus ()) {case SUCCESS:log.info ("Alipay success:)");

        System.out.println ("Payment PO Pre-single success:)");
Alipaytradeprecreateresponse response = Result.getresponse ();
Dumpresponse (response); System.out.println (Response.getboDY ()); Need to be modified to run the path on the machine//String FilePath = String.Format ("/users/liuyangkly/qr-%s.png", Response.getouttradeno
());
Log.info ("FilePath:" + FilePath);
Zxingutils.getqrcodeimge (Response.getqrcode (), 256, FilePath);

        System.out.println (Response.getqrcode ());  Generate orders, insert database Baobiaoorder order = new Baobiaoorder (userid, Outtradeno, "", double.parsedouble (amount), New Date (),
        1);

        Baobiaoorderservice.insertorder (order);
        Map.put ("Status", "true"); Map.put ("QRCode", Response.getqrcode ());

        Returns to the client two-dimensional code map.put ("Outtradeno", Outtradeno);

      return map;
        Case FAILED:log.error ("Payment PO Pre-Failure!!!");
        System.out.println ("Pay treasure to advance a single failure!!!");
        System.out.println (Result.getresponse (). GetBody ());

      Break
        Case UNKNOWN:log.error ("system exception, pre-single State unknown!!!");
        SYSTEM.OUT.PRINTLN ("System exception, pre-order status unknown!!!");

      Break
 Default:log.error ("Unsupported transaction status, transaction return anomaly!!!");       SYSTEM.OUT.PRINTLN ("Unsupported transaction status, transaction return anomaly!!!");
    Break
    } map.put ("Status", "false"); Map.put ("MSG", "system abnormal, please try again later!")
    ");
  return map;

 }

Then the logic is that the user will use the mobile phone scan code to pay Alipay payment, and then Alipay received will send a payment to the success of the message to our set of Notify_url, as follows:

@RequestMapping (value = "/pay/notify", method = requestmethod.post) public String notifyresult (HttpServletRequest reque St, httpservletresponse response) {Log.info ("receive an asynchronous notice of Alipay!")
    ");

    map<string, string> params = new hashmap<string, string> ();
    All parameters are removed to verify the signature enumeration<string> parameternames = Request.getparameternames ();
      while (Parameternames.hasmoreelements ()) {String parametername = parameternames.nextelement ();
    Params.put (ParameterName, Request.getparameter (parametername));
    Boolean signverified;
    try {signverified = Alipaysignature.rsacheckv1 (params, Configs.getalipaypublickey (), "UTF-8");
      catch (Alipayapiexception e) {e.printstacktrace ();
    Return "Failed";
      } if (signverified) {String Outtradeno = params.get ("Out_trade_no"); Log.info (Outtradeno + "order callback notification.)
"); System.out.println ("Verify signature successful!")
      "); Log.info ("Verify signature successful!")

      "); If the AppID in the parameter is not the same as the AppID filled in, the exception is notified if (! Configs.getappid (). Equals (Params.get ("app_id"))) {Log.warn ("Unlike the AppID at the time of payment, this is an exception notification and should be ignored!")
        ");
      Return "Failed"; ///Find the order number in the database and compare the amount to the amount in the database, and if not, also notify baobiaoorder order = Baobiaoorderservice.findorderbyouttraden
      O (Outtradeno); if (order = = null) {Log.warn (Outtradeno + ") Check no such orders!"
        ");
      Return "Failed"; } if (Order.getamount ()!= double.parsedouble (Params.get ("Total_amount"))) {Log.warn ("unlike the amount at the time of payment, this is an exception notification, should be ignored!")
        ");
      Return "Failed"; if (order.getstatus () = = baobiaoorder.trade_success) return "SUCCESS";
      If the order has been paid successfully, simply ignore this notification String status = Params.get ("Trade_status"); if (Status.equals ("Wait_buyer_pay")) {//If status is waiting for user payment if (order.getstatus ()!= Baobiaoorder.wait_buyer_pay) Baobi
      Aoorderservice.modifytradestatus (Baobiaoorder.wait_buyer_pay, Outtradeno); else if (status.equals ("trade_closed")) {//If the status is unpaid transaction timeout closed, or payment completed after full refund if (Order.getstatus ()!= BaobiaoorDer.
      trade_closed) Baobiaoorderservice.modifytradestatus (baobiaoorder.trade_closed, Outtradeno); else if (status.equals ("trade_success") | | | status.equals ("trade_finished")) {//If the status is already paid successfully if (Order.getstatus (
      )!= baobiaoorder.trade_success) baobiaoorderservice.modifytradestatus (baobiaoorder.trade_success, Outtradeno);
      else {baobiaoorderservice.modifytradestatus (baobiaoorder.unknown_state, Outtradeno);
    Log.info (Outtradeno + "The status of the order has been modified to" + status);
    else {//If the verification signature does not pass return "failed";
  Return to "success";

 }

This is probably the case, but less to the client to send payment successful notification, there are some security issues.

Finally, summarize the problems encountered in this process:

1. Alipay returned two-dimensional code can not be opened directly in the browser, but to use two-dimensional Code conversion tool to generate two-dimensional code, or through cli.im this site to view
2. Pay treasure sandbox environment generated two-dimensional code can only use the sandbox version of the mobile phone Alipay to sweep the code, the normal version of the payment of the treasure sweep will appear this two-dimensional code expiration and so on error
3. If the payment is not received after the payment PO sent asynchronous notification, you can use postman and other tools to check the completion of the Notify_url can be used public network IP access to
4. If the problem with the ISV's lack of permissions is because there is no sign or application does not add the corresponding function, the application is not online and can not be used, the development of the time to choose the sandbox application
5. Sandbox version of the mobile phone payment treasure when the registration can not receive text messages, contact customer service to ask for an account

The above is the entire content of this article, I hope to help you learn, but also hope that we support the cloud habitat community.
