Payment Treasure Interface Demo document download

https://doc.open.alipay.com/doc2/detail.htm?spm=a219a.7629140.0.0.qAEbso&treeId=62&articleId=103566 &doctype=1 Create feedback table payment business logic processing

1, the payment interface of "partner ID" and "key" to apply for their own, here skipped

After downloading the demo document, choose the language and coding format for your project, which is Java-utf-8
Then import into your project (the directory structure itself is free to compose, I use the format provided by the document)

Then go to the alipayconfig to fill in the requested partner ID and key.

2, the Alipayparams of feedback information table
(The table is also not created, primarily to be able to record information about each transaction's information recording details)
Refer to the document contents of the instant to account transaction interface-"Server asynchronous notification parameter description"
Create a Alipayparams table

DROP TABLE IF EXISTS m_alipayparams; CREATE TABLE m_alipayparams (payid int UNSIGNED not NULL auto_increment PRIMARY KEY, PayType Int (one) DEFAULT 0 comme NT ' Order: 0-paid, 1-refund, 2-present, 3-top-up ', sign VARCHAR (MB) default null COMMENT ' signature ', Sign_type VARCHAR ($) default NULL COMM  ENT ' signature method ', Paymethod VARCHAR (MB) default null COMMENT ' payment method: DirectPay (Balance Payment) ', notify_id VARCHAR (MB) default null COMMENT ' notification checksum ID ', notify_type VARCHAR default NULL COMMENT ' notification type dsa/rsa/md5 ', Notify_time DATETIME DEFAULT NU LL COMMENT ' notification time ', Trade_no VARCHAR (MB) default null COMMENT ' Alipay transaction number ', Out_trade_no VARCHAR (MB) default NULL comme NT ' Merchant website unique order number ', subject VARCHAR (257) default null COMMENT ' commodity name ', Payment_type VARCHAR (one) default null COMMENT ' Payment class

Next step in the consolidation implementation
in the download Alipay demo document, you can see that alipayapi.jsp and notify_url.jsp

Translate the code from these two pages into Java writing Alipayaction.ja VA
