How Java integrates Alipay.

Need to pay treasure "partner ID and Security check code key"; If you can't make it, there's no need to keep looking down.

First we need to download the Alipay integrated instant to post interface file, as shown below.

What we're using is, of course,

Create_direct_pay_by_user-java-utf-8

Open Directory

The file inside is similar to our Java Web project. , in fact, it is a common Java project, we may want to first import it into the myeclipse.

The following figure:

There's no need to study what's in it first, we'll add it to the Tomcat container and let him run and let's see what's inside. Read the code through the page.

Open the browser, first access to the next index.jsp

Discover this is a PayPal offer for our integrated Alipay test page, so let's test it first.

configure some things first.

At this point, we need our partner ID and security key. Open the/alipay/src/com/alipay/config/alipayconfig.java class. Configure three information and how to configure it. The comment is clear enough.

After the configuration is complete, you can test it. Open the index.jsp page. The form of this page is to be submitted to alipayapi.jsp for processing. You can see from the code below the index.jsp.

<form name=alipayment action=alipayapi.jsp method=post target= "_blank" >

After we open the Index.jsp page, click OK to enter the information as required.

and start submitting.

, you can see the payment page, let's pay for it, 1 cents or some,

After payment.

, and then this is the page

, after a successful payment, a callback to the return_url.jsp,

This is the page.

Look at the code inside to

<% * * Function: Alipay page Jump Sync notification page version: 3.2 Date: 2011-03-17 Note: The following code is only for the convenience of merchant test sample code, merchants can according to their own website needs, according to technical documentation, not necessarily to use the code.

 The code is only for learning and research Alipay interface use, but provides a reference.

After reading, the inside is to accept some parameters, and then verify that the payment is successful, after success, we have to the database of their own website to operate.

This return_url.jsp is a page that synchronizes the callback.

We also saw the notify_url.jsp this page. This is an asynchronous callback. is paid after the success of Alipay to our website unsolicited request, all this can only be completed on the server-side debugging.
It has the same structure as return_url.jsp.

And then there's this alipayapi.jsp, when we index.jsp submit the request to alipayapi.jsp. Let's see what it does with those things.

<% * * * Function: Instant to account Transaction Interface Access page * Version: 3.3 * Date: 2012-08-14 * Description: * The following code is only for the convenience of merchant test sample code, merchants can according to their own website needs, according to technical documentation, not necessarily to use the code.

I found out that he accepted the index.jsp data, then packaged the/alipay/src/com/alipay/config/alipayconfig.java configuration information into a map collection to create a request and returned a string. This return does not matter, the key is his request, and then we see the result, that is, to reach the payment page.

Integration is as simple as that. Of course the code does not need to use Alipay code, we can expand our thinking, put its key code, add to our business class. Make a call.
