Java implementation Micro-letter payment (service side) _java

Do not say much nonsense, directly look at the code.

RequestHandler RequestHandler = new RequestHandler (Super.getrequest (), Super.getresponse ());
 
Get Token//Two hours in effect, two hours later regain
 
Token = Requesthandler.gettoken ();
 
Update token to the application
 
requesthandler.gettokenreal ();
 
SYSTEM.OUT.PRINTLN ("micro-credit payment acquisition token=======================:" +token);
 
RequestHandler Initialization of
 
requesthandler.init ();
 
Requesthandler.init (Appid,appsecret, Appkey,partnerkey, key);

Code: Local System Build Order

Set Package order parameters sortedmap<string, string> packageparams = new treemap<string, string> (); Packageparams.put ("Bank_type", "WX"); Payment type Packageparams.put ("Body", "xxxx"); Product Description Packageparams.put ("Fee_type", "1"); Bank currency Packageparams.put ("Input_charset", "UTF-8"); Character Set Packageparams.put ("Notify_url", "Http://xxxx.com/xxxx/wxcallback");
 
  The notification address here uses an extranet address test to see if Port 80 is open. Packageparams.put ("Out_trade_no", no); Merchant Order number Packageparams.put ("partner", Partenerid); Set up merchant number Packageparams.put ("Spbill_create_ip", Super.getrequest (). Getremotehost ()); Order generated machine IP, refers to the user browser-side IP packageparams.put ("Total_fee", String.valueof (Rstotal)); 
 
  Total amount of merchandise, to be divided into units//Set up payment parameters sortedmap<string, string> signparams = new treemap<string, string> (); 
 
  Signparams.put ("AppID", AppID); 
 
  Signparams.put ("Noncestr", noncestr); 
 
  Signparams.put ("Traceid", Propertiesutils.getorderno ()); Signparams.put ("timestamp", timestamp); 
 
  Signparams.put ("package", packagevalue);
 
 
 
  Signparams.put ("Appkey", This.appkey); 
 
  Generate payment signatures, to use the original value of Urlencoder SHA1 algorithm!
 
    String sign = "";
 
    try {sign = sha1util.createsha1sign (signparams);
 
    catch (Exception e) {e.printstacktrace (); 
 
  //Increase the extra parameter signparams.put ("Sign_method", "SHA1") for the non-participating signature;   
 
  Signparams.put ("App_signature", sign); API Payment LCL End------------------------------------//Get Prepayid String Prepayid = Requesthandler.sendprepay (signpar
 
  AMS);
 System.out.println ("Prepayid:" + Prepayid);

code: Generate prepaid Quick order complete  

 Generate prepaid Quick order completion and return the parameters required for Android,ios to drop the micro-letter. 
 
  sortedmap<string, string> payparams = new treemap<string, string> ();
 
  Payparams.put ("AppID", AppID);
 
  Payparams.put ("Noncestr", noncestr);
 
  Payparams.put ("Package", "Sign=wxpay");
 
  Payparams.put ("Partnerid", Partenerid);
 
  Payparams.put ("Prepayid", Prepayid);
 
  Payparams.put ("Appkey", This.appkey);
 
  In addition to the 1000 is because of the parameter length limit.
 
  int time = (int) (System.currenttimemillis ()/1000);
 
  
 
  Payparams.put ("timestamp", string.valueof (time));
 
  
 
  System.out.println ("timestamp:" + time);
 
  Signature String paysign = "";
 
  try {paysign = sha1util.createsha1sign (payparams);
 
  catch (Exception e) {e.printstacktrace ();
 
  
 
 } payparams.put ("sign", paysign);
 
  Spell-JSON data is returned to the client basicdbobject Backobject = new Basicdbobject ();
 
  Backobject.put ("AppID", AppID);
 
  Backobject.put ("Noncestr", Payparams.get ("Noncestr"));
 
  Backobject.put ("Package", "Sign=wxpay"); Backobject.put ("PaRtnerid ", Payparams.get (" Partnerid "));
 
  Backobject.put ("Prepayid", Payparams.get ("Prepayid"));
 
  Backobject.put ("Appkey", This.appkey);
 
  Backobject.put ("timestamp", Payparams.get ("timestamp")); 
   
  Backobject.put ("Sign", Payparams.get ("sign"));
 
  String backstr = dataobject.tostring ();
 
  System.out.println ("Backstr:" + backstr); return backstr;

So far, the prepayment order has been generated and the client has been returned to wait for the micro-server notification, and the address of the notification is the notify_url that generated the prepayment order

 ResponseHandler Reshandler = new ResponseHandler (request, response);
 
  Reshandler.setkey (Partnerkey);
 
  Create Request object//requesthandler Queryreq = new RequestHandler (request, response);
 
  Queryreq.init (); if (reshandler.istenpaysign () = = True) {//Merchant order number String Out_trade_no = Reshandler.getparameter ("Out_trade_
 
      No ");
 
      System.out.println ("Out_trade_no:" + out_trade_no);
 
      Tenpay order number String transaction_id = Reshandler.getparameter ("transaction_id");
 
      System.out.println ("transaction_id:" + transaction_id);
 
      Amount to be divided into unit String Total_fee = Reshandler.getparameter ("Total_fee");
 
      If a discount coupon is used, the discount has a value, total_fee+discount= the original request Total_fee String discount = reshandler.getparameter ("discount");
 
  
 
      Payment result String Trade_state = Reshandler.getparameter ("Trade_state");
 
        To determine the signature and result if ("0". Equals (Trade_state)) {//------------------------------//Instant to account processing business start //------------------------------System.out.println ("----------------Business logic Execution-----------------");
 
        --Write a program based on your business logic (the above code is for reference only)--system.out.println ("----------------Business logic completed-----------------"); SYSTEM.OUT.PRINTLN ("Success");
 
        Please do not modify or delete System.out.println ("Instant to account payment success");
 
   
 
       Send the success information to the Tenpay system, Tenpay the system receives this result no longer follow the notice reshandler.sendtocft ("Success");
 
     To the micro-mail server return to success otherwise 30 minutes notice 8 times returns "Success";
 
      }else{System.out.println ("Notify Signature verification failure");
 
      RESHANDLER.SENDTOCFT ("fail");
 
    Response.setcharacterencoding ("Utf-8"); 
 
  }}else {System.out.println ("Fail-md5 failed"); }

The above is the Java implementation of the micro-letter payment server to provide the code, I hope that you study carefully to achieve micro-letter payment.
