Java如何集成支付宝即可到账接口

Java如何集成支付宝？

需要支付宝【合作者身份ID和安全校验码KEY】；如何这个你都搞不定，就没有必要在继续往下看了！！！！！！！！！！！

首先我们需要来先下载支付宝集成即时到帐接口文件，如下图。
这里写图片描述

我们用到的当然是

create_direct_pay_by_user-JAVA-UTF-8

打开目录

这里写图片描述

里面的文件跟我们的Java Web项目类似吧？，其实它就是一个普通的java项目，不妨我们先将它导入到Myeclipse中。

如下图：

这里写图片描述

没必要先研究里面都是什么东西，我们先把这个项目加入到tomcat容器里，让他跑起来，让我们去看看里面究竟是一些什么东西。通过页面去了解代码。

这里写图片描述

打开浏览器，先访问下index.jsp

这里写图片描述

发现这是一个支付宝提供给我们的集成支付宝的测试页面，那么我们先来测试一下。

先配置一些东西。

这时候就需要我们的合作者ID和安全密钥啦。打开/alipay/src/com/alipay/config/AlipayConfig.java类。配置三个信息即可，如何配置？注释已经说的够明确了吧？

这里写图片描述

配置完毕后，就可以测试了。打开index.jsp页面。这个页面的表单是要提交到alipayapi.jsp中处理的。从index.jsp下面这个代码就可以看出来了。

1 <code class="hljs oxygene has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;"><form name=alipayment action=alipayapi.jsp <span class="hljs-function" style="box-sizing: border-box;"><span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">method</span>=<span class="hljs-title" style="box-sizing: border-box;">post</span> <span class="hljs-title" style="box-sizing: border-box;">target</span>="_<span class="hljs-title" style="box-sizing: border-box;">blank</span>"></span></code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li></ul>

我们打开index.jsp页面之后，按照要求输入信息点击确定即可。

，开始提交。

，就可以看到支付页面了，我们来支付一下，1分钱嘛还是有的，

支付之后。
这里写图片描述

，然后就是这个页面

这里写图片描述
，支付成功后，回调了return_url.jsp，

就是这个页面

看看里面的代码把

看完之后，里面就是接受了一些参数，然后验证一下支付是否成功，成功之后，我们要对自己网站的数据库进行操作。

这个return_url.jsp就是一个同步回调的的页面。

我们还看到了notify_url.jsp这个页面。这个是异步回调。是支付成功后，支付宝向我们的网站主动发生请求，所有这个只能在服务器端调试完成。
它的结构，和return_url.jsp一样。

然后就是这个alipayapi.jsp，当我们冲index.jsp提交请求到alipayapi.jsp的时候。让我们看看它做了那些事情？

我么发现他就是接受了index.jsp的数据，然后结合/alipay/src/com/alipay/config/AlipayConfig.java的配置信息打包成map集合建立了一次请求，返回了String。这个返回无关紧要，关键是他的这个请求，然后我们看到了结果，即到达付款页面。

集成就这么简单。当然代码没必要用支付宝的代码，我们可以拓展我们的思维，把它的关键代码，加入到我们的业务类中。进行调用。
