在线支付功能
不得不说今天做出了在线支付，从内而外的好开森呐，真的是在线支付啊，还花了我一分钱呢，刚开始我还有点不相信
一、在线支付方式：分为两种，并且他们都各自有优缺点
第一种方式：网站与各个银行的网银进行对接
第二种支付方式：网站先与第三方支付公司进行对接，第三方支付公司再与各个银行的网银系统进行对接
二、在线支付的流程分析（这里用到的是与第三方支付公司易宝对接）
网站重定向到第三方支付公司，再重定向跳转到网银系统，在网银中付款完成再次重定向到第三方支付公司，然后通知你的网站支付成功，回到你的网站。期间各种重定向需要传递很多数据信息，如何保证数据安全，这里就有了电子签名（账号，加密算法，秘钥）。
第三方支付产品接口文档是很关键的：1.支付请求参数说明，需要向易宝提交的数据；2.支付结果参数说明，网银支付成功之后，第三方支付公司带回网站的信息
三、业务分析
订单付款的功能:
* 在线支付的方式：
*与第三方支付公司对接：（易宝）
*在线支付的流程：
*付款功能代码实现：
*修改订单数据：（收货人，地址，电话）
*完成付款的功能
四、代码实现
order.jsp页面传递一些网站页面的信息，如收货人，地址电话，然后转到要执行action的方法

OrderAction类中接收支付通道编码，也就是选择哪个银行；为订单付款包括修改订单（传入收货人，地址，电话）到数据库。为订单付款（调用第三方公司的接口，传入所需要的参数）。付款成功后的转向：修改订单状态为已经付款。在页面显示付款成功信息。交易结果返回类型r9_BType有两种：为“1”：浏览器重定向（浏览器重定向到第三方再重定向到网站），为“2”：服务器点对点通讯（网银通知第三方支付公司，收到钱以后，向固定ip地址的网站上输出“2”）

小结：在线支付功能在以后做电商类的项目中是肯定少不了的，调用第三方确实方便了好多，只需要调用第三方接口按照第三方文档传入对应的参数即可，算法工具类的一些加密算法是少不了的，数据传输过程中的安全问题才是最重要的，数据重定向返回时的一些判断这里没有写，以后一定要注意一些判断和支付安全问题。
