KEEP_MOVING 人气:0想了解基于Java代码实现支付充值的通用流程的相关内容吗,KEEP_MOVING在本文为您仔细讲解java支付充值的相关知识和一些Code实例,欢迎阅读和指正,我们先划重点:java支付充值,支付充值流程,下面大家一起来学习吧。
废话不多说了,直接给大家贴java代码了。
具体代码如下所示:
/*支付流程*/ /****Controller.java 代码如下:*/ @RequestMapping(value = "/paySubmit.htm", method = RequestMethod.POST) public ModelAndView paySubmit(HttpServletRequest request, HttpServletResponse response, @RequestParam Map<String, Object> maps){ ModelAndView model = new ModelAndView("***/submit");
